    $62.57 delivery? It better be delivered bya a THX certified barbershop quartet.

    • My postcode was $69.72.

      That pushes the price up past what I paid for my speakers when they were on sale at JB Hifi several years ago.

      They better be breaking out a parade for that price.

    • $62.57 Delivery? It better be delivered by John Aux himself.

      • I Googled John Aux

        • Does he look like an Ox?

        • +1

          I'm sorry for that

    Have 2 sets of these, great speakers.

    • Yes, for the price, they are really excellent.
      I use them for my HTPC/gaming system.
      Also, they have a nice little aux in on the right speaker (above the headphone jack). Recently I bought one of those $1.26 bluetooth receivers from gearbest, so now I can listen to music from my phone (even when my PC is turned off).
      All for $100.26
      Sweet!

      • what's diff between aux and headphone jack ?

        • +1

          Aux is an input, headphone is an output

  • +9

    I have a set of these and I don't recommend them. (What's the bet I get negged).

    They are slightly louder/cleaner on the bass end than 5.1 X530 and X540 speakers (Those were the previous sets of 5.1 speakers that came before the z506). But they really lack on the high end. Over all they not as loud as the 5.1s. I was a bit surprised when I compared head to head.

    I was intending to use them as party speakers for my kids' birthday parties every year as the X530 set I use requires more time due to more cables and plugs and I wanted to spend the time doing other things (like taking photos). That hasn't worked out because this speaker isn't going to be loud enough for use in a medium sized back yard where the X-530s are (just).

    The high end is definitely not just not as loud but muddier and slightly buzzy if turned up all the way on the Z623. The bass is cleaner though. That might be a good trade off if you're into doof doof I guess.

    I keep meaning to flip the z623 I bought but I never get around to it.

    Both my local office works will only price match including delivery.

    • what would you recommend at $99 then?

      • +3

        Logitech z506 is $99 at Officeworks and probably cheaper elsewhere. I'd probably try to find a special and save some money. Have bene as low as $58 on Ozbargain (via Harvey Norman) but long expired.

        I remember picking up my X-530 speakers almost 10 years ago for $59 which was a steal at the time. Walking back to work carrying 2 was comical.

    • strange to get that real world feedback.

      Z506 - 75W RMS total; sub 27, centre 16, and 4x8
      Z623 - 200W total; sub 130 and 2x35

      apples and oranges….

      I thought maybe Z623 was listed as PMPO or some other rating, BUT there is a bit that says 400 peak power, and another bit claims 200W is RMS.

      • +1

        The Z623 must have dogsh*t efficiency compared to the Z506. The watts must be going elsewhere, heat I guess - perhaps better for winter listening

        • +1

          I have the Z623. It delivers good sound for the price, as reviewed above.

          Two negatives:
          * The woofer box, which contains the amp gets warm (~35'C) when it is idling, not playing anything.
          * The tweeters are fake, there is nothing behind the THX badge, even though it is meant to look like a tweeter.

      • coz the mid and high ar directional, when u try to use it in our back yard party a 5.1 system works better.

        • Speakers sit less than 1m apart on the same desk all pointed in the same direction.

          The 5.1s have 10 cones and the 2.1s have 2 cones.

        • @syousef:
          na, thats not how it works,
          more cones gives u wider angle of coverage area, how loud you could get depends on the input power.
          let me say it this way, during the night 2 laser beams vs 5 flashlights which one could make u c ur backyard better? u think u ar pointing the flashlights in the same direction but still not the same concept as the laser beams, in an openfield area such as ur backyard, 5.1s works much more efficiently then a 2.1s.
          and btw those ar not designed for out door or large room party use, z623 sounded much better then z506 in a home theater environments.

        • @samelight:

          All I can tell you is that subjectively and also with a cheap dedicated sound meter, the 10 cones of the x-530 output more volume than the 2 cones of the z623. In my study or in the backyard.

          I'm not willing to go to the trouble of a more scientific setup or even a Youtube demo video.

        • @syousef:
          i dont know how u measure it, but it is highly regarded to how and where you place the cones and the meter.
          not to mention the sound meter receiver is directional too,

          and more importantly i don't understand the logic behind this measurement, a sound meter can only measure the noise level, you can not tell whether is peak level or RMS from the results.
          x-530's total peak=140w, 50w for the sub and 90w for the satellites,
          and
          z623's RMS only got 130w for the sub and 70w for the satellites.
          if u ar using a song but without a suitable amplifier to test it, this is most likely u will get.

        • @samelight:

          Argue with me all you like. My wife, my son, my meter and I all agree.

          As a geek I'm fascinated by the tech specs. But as a user I just don't care. Louder is louder. I bought for louder based on the tech specs and I was burnt.

          Same source btw.

        • @syousef:
          "Same source" thats the ur problem, z623 ar designed to accept higher power source to reach its much higher maximum volumes, think about headphones, u won't get the same loudness from hd598 and hd800 with the same source, not even close!!
          Louder is louder? so what u saying here is z623 got a higher maximum power and therefore it should sound louder regardless the input source?
          how u call urself a geek dude!! u just looked on the tech specs crying out loud without knowing what it means.

        • @samelight:

          So wait you are suggesting the right way to compare 2 speakers for the same job is to plug them in to different sources? Without even knowing what same source(s) I used? (There were 3). And you are then questioning my geek credentials? Two things you should look up. 1. Confitmation Bias. 2. Dunning Kruger.

          Since you understand those tech specs so well would you care to tell me how much louder in decibels you think 5W RMS is compared to 50W?

        • @syousef:
          So wait you are suggesting the right way to compare the speed of a petrol car and a diesel car is fill them both with diesel and run it?
          i dont need to know what source(s) u used for both, coz i know what happen when u plug a heaphone into an audio amp and run it with full volume! ur x-530 still got an output sound that means u ar not using a corresponded amplifier for z623, how u talk about the maximum volume without actually maximize it?
          we ar not talking about regular use here right? dont get me wrong, i got no problem with u testing it with the same soure for regular uses, but u ar talking about max volume on party speaker for god sake!

        • -1

          @syousef:
          heres what happened,
          you bought 2 flashlight on ebay,
          first one 500LM only can use aa battery,
          second one 2000Lm with 18650 battery u can also use an aa battery,
          then u test them both with aa battery and complaint about the second one not as bright as the first one, u were fascinated by the tech specs and burnt…
          i dont want to argue with u anymore, whatever u say "I all agree".

        • @samelight:

          See that's just plain insulting. You have no idea how I tested the speakers, because you weren't there and you didn't bother to ask me.

        • @samelight:

          @syousef is correct. Do you actually own these two systems?

          I have tested with multiple sources:

          1) iBasso D2 Boa+, puts out plenty of power, much more than any PC or mobile. Volume knob at 4 o'clock and the Z506 is louder.

          2) Hifimefiy sabre -> iBasso. Same results.

          3) PC out, again, louder.

          4) Headphone out on my HT receiver (TX-NR709), Z506 ahead again.

        • -1

          @syousef:
          See that's just plain insulting of my IQ, if u 18650 battery on the first flashlight it will blowup, same as what happen when u run diesel in petrol car, headphone with audio amp, do i really need to ask u?

        • +1

          @samelight:

          You have no idea of my setup. You didn't bother to ask about the specifics, and you compare it to putting too high a voltage through a circuit or putting diesel in an petrol car. THAT is what is insulting.

          You literally have no clue what I did. You didn't ask me. You assumed a bunch of things about what I did including that my source was underpowered, didn't bother to ask or verify, insulted my geek cred and now you're putting up straw men and reductio ad absurdum arguments. So far I've resisted insulting your IQ, but you're pushing.

          And to top it off someone else who owns both the systems has chimed in and agrees as above.

          Further it wouldn't even matter if the Z623 was louder with an atypical source. Most people are going to plug in a computer, phone or tablet.

        • -4

          @donnot:
          u dont even know what we talking about and u start to take sided ?
          not Z506, is "x-530" dude! open ur eyes plz!
          go google its connector first be4 u throw out the "iBasso D2 Boa".
          and btw with "iBasso D2 Boa" Volume knob at 4 o'clock either one of Z506, x-530 or z623 could make u deaf, the noise volume way pass any regular 130db sound meter can measure.
          TX-NR709 "Volume knob at 4 o'clock", they will all burned coz none of them ar designed for that amount of voltage input.

        • -3

          @syousef:
          the max input power limited the way u could set it up, i dont need to ask u anything, x-530 is designed for pc and console if u hook it up with an amp it will blowup,
          so what u want me to ask u specificly? did u hook it up with an amp and it blowup??
          or maybe i should ask u how u hook it to an amp without blowing it?

          and the "someone else who owns both the systems has chimed in and agrees as above" hes bs.
          "z506" dude! "Volume knob at 4 o'clock"… i dont know dude, he just sounded so stupid.

        • @samelight:

          Now I know you're just trolling now.

          X-530s and Z623 have the same modes of connection and the same input specs. Both include an amplifier and don't require a separate amp.

          z506 is the model that supercedes the X-540, that supercedes the x-530. All very similar speakers.

          I don't know why you've put scare quotes around "z506" or why describing the volume knob by position supposedly makes someone else "sounded so stupid", but this isn't a school yard or day care.

        • @samelight:

          Ahh…obvious troll is obvious. I stated that the iBasso's volume was at 4oC, not the Onkyo (though, it should be able to handle it). 4oC is referring to ~80-90%, as there is a bit of a jump on the top end, my apologies.

        • @donnot:
          plz dont talk, we ar not talking about "z506" here, so clearly u ar off the topic, doesn't matter 4oC or something else.
          u dont even know what we arguing but u said "@syousef is correct", i dont know wtf u doing here mate.

        • @syousef:
          now i know u don't actually own these two systems now, as the input;
          Z623 using 2xRCA (thats for the fk amp or home-theatre) and 1x3.5mm, same to the z506.
          X-530s only got 3x 3.5mm connectors connect to the back of ur pc for rear / front /center sub. if u want to connect X-530s to a console u need an adapter, if u hook it up to an amp with that adapter, it will blowup first. Same as the X-540,

          the differences between "z" and "x" series is the input connector type and how much power input they can take. they all don't require a separate amp to drive, but with "z" series u can connect it to a home-theatre system with the RCA connectors, it won't blowing it up, and of coz u could get a higher volume with a setup like this.
          with the "x" series if u try to convert those 3.5mm connectors and hook them to an amp/home-theatre, it will blowup, simple as that!
          dude i feel like im talking to a 3yrs kid, u know nothing and try to bs ur way out.

          btw we ar talking about X-530s and Z623, he jumps in and agree with u on z506 ar louder?? i dont know what else i could call that.

        • Misread his comment, sandp's comment put me off by comparing the power output of the Z506 and Z623, so I compared those two. My bad.

          No reason for syousef to lie about owning these systems, especially with his first comment in this thread.

        • @donnot:
          i got no idea why he lies too, but is so obvious when it came to the connector types. he don't even know where and what they plug into.

        • @samelight: why did you just call him a liar?

          Do you understand db vs watt?
          My lawnmower has a power output of about 1600w however its 75-80 db.

          My home theatre is about 75w per channel and will hit 115db in stereo.

        • @bigjezza:
          why did I just call him a liar? coz he don't even know whats the input connector tpye of those 2 systems ?

          Do I understand db vs watt? Do u know u ar off the topic right now ? do you know whether i understand db vs watt or not still won't change the fact that he doesn't know whats at the back of those 2 systems?

          more importantly do you know all those lawnmower and home theatre u have said won't proof or disproof anything of what me and syousef ar arguing ?

          why u here ? why u post something like this ? whats ur point ?

        • @samelight:

          Now you're calling me a liar? Not mistaken. A liar. Not hey you're wrong about that. Are you at home staring at them? No straight to "Now I know you don't own them."

          In any case you're just plain wrong. Hooking up an amplifer to the RCA jack on the z series doesn't bypass the internal amplifier. The documentation states you can connect your source to either the RCA jacks or the 3.5mm jacks. If you plug in your source to the RCA jacks and give it too much juice you'll blow up your amp just the same as through the 3.5mm jack.

          The dedicated AUX in on the z series doesn't mean you're going to get more volume out of them. EVERY review I've seen puts the volume of the X-530, X-540 and z506 at very similar levels volume wise. You don't magically get more volume out of the z series speakers using a dedicated external amp.

          In summary you're just talking complete rubbish and expecting others to eat it up.

          If you look at the thread, the message you replied to mentioned the z506. As did I. If you don't want to bother to read, that's your issue.

          And oh look. Instructions for the Z506 include reference to "nine o'clock position" and "twelve o'clock position"
          https://www.manualslib.com/manual/360183/Logitech-Z506.html?…
          Perhaps you should write to Logitech and tell them "it sounds so stupid" too. Why should only Ozbargainers receive your bile?

          Btw since you didn't bother to answer the theoretical difference between 75W and 200W is roughly 4-5 decibels. You get about 3 decibels for every doubling. If you want double the volume you need roughly 10x the power.
          https://www.cnet.com/forums/discussions/75-watts-rms-what-do…

          You know what, go troll someone else. I'm just bored with you. When you decide to stop talking to people as if they're 3 year olds, and hurling abuse as it it's proof while making no sense, look me up. I suspect I'll be waiting a while.

        • @syousef:
          who said anything about Hooking up an amplifer to the RCA jack on the z series will bypass the internal amplifier?? where u came up with that idea? what make u think u can't hook 2 amp?
          who said anything about give it too much juice it won't blowup? i said "z" can take more juice the "x", anything will blowup with too much juice .
          who said anything about "The dedicated AUX in on the z series mean you're going to get more volume out of them."?? it means it could take more juice first, then u will get more volume.
          who said anything about the "Z506"'s o'clock position? not him, not me !plz open ur damn eyes we ar talking about the Volume knob on the "iBasso D2 Boa+", now i can call u stupid too, coz u dont fk read!!!
          i didn't bother to answer the theoretical difference between 75W and 200W?? who asked ?! wow !really ?!where the hell is that from ?! and it can change the fact that u dont even know what connectors ar at teh back of those 2 systems?

          You know what, u ar running out of excuse, thats why u made up so many bs hurling abuse as it it's proof while making no sense, look me up. I suspect I'll be waiting a while.

          @samelight: as a home user that needs gigabit lan I am quite confused what your beef is.

          So we have two speaker systems. Hooked up to the same source. One is louder than the other! I don't give a rats ass about diesel or batteries.

          You need to write with more clarity. You seem to be failing at communicating with an effective point. Can you please try again at conveying your thoughts?

        • @bigjezza:
          its ok, im confused when u talk about lawnmower too,

          i did made myself clear, if u dont read or dont give a rats ass about this and that then of coz u arc onfused.
          let me get this straight, again, just for u my dear,
          syousef was complaint about z623 not as loud as X530, hes fascinated by the tech specs bought it based on the tech specs and burnt.
          my point is the maximum out put volume for z623 ar backed by the home theater/amp source, if u test them both with a pc source then z623 won't have the "fascinated" tech specs u expected,
          and if u use the home theater/amp as source to test them both, the X530 will blowup be4 the source reach its maximum level, becoz X530 only designed to be used in with pc(a special designed adaptor for the console).
          simple as that! any more questions my darling? if u got no more questions then i suggest u go get a life, wow u still remember my ID+ the gigabit lan… u ar sad dude.

        • @samelight:

          Yes I have a question, why the hell do you think I'm your darling? And another come to think of it. Why do you think repeating incorrect information in an insulting way makes it somehow correct? You have nothing new to say, other than the insults.

        • @syousef:
          if u ar not using 2 ID then im not talking to u and didn't not call u "darling". once again open ur eyes and READ !!!
          i dont want to insult u but u keep BS like this plz tell me what can i say except the word "blind"? u ar blind, thats why all u can c is "incorrect information in an insulting way", u c what u choose to c.

        • @samelight:

          Oh I'm sorry did I not read your abuse accurately?

          I can feed the z623 enough volume to make them buzz badly enough I'm afraid I'm going to blow the thing, but you think all I need to do is make it go through an amp and magically it delivers more volume.

          You're running around and calling people names like an 8 year old and accusing them of lying, and I'm suppose to work out who you're abusing.

          All the sound goes through the same drivers which can't handle any more volume, and you can't bypass the amp using the AUX in. Can I make it any clearer to you? Even if the plugs could take more juice, the speaker can't output more. Capiche?

        • @syousef:
          lets forget about the damn speaker, im more worry about the "darling" part now,
          plz plz tell me u ar not using 2 ID to reply like this! coz its just so sad, and feel so so bad of making u feel insulted or humiliated.

        • @samelight:
          Thanks bae for clarifying that. So what line input level does the z623 really shine at? 2vrms? That's approx what a nice ht should output.

          And you certain the 530 will blow on that? Most things I've played with required more effort than that to blow, sugarbuns.

        • @bigjezza:
          damn i can't talk to u 2 or u 1 right now coz of the guilt…
          i can't think straight, im sorry for u 2 or u 1, i really am. and plz forgive me with the "gigabit lan" too, i could never imagine how it harme you for so long… im srry and wish u all the best

        • @samelight: We are 2 or more ppl fyi.

          The gigabit lan was the first post I clicked on after your name. It was like striking gold while expecting to find mouldy newspaper.

          I wonder what other nuggets are there. Alas I've no time for digging.

        • @bigjezza:
          u think that make it sounded better ? no sweetheart, it doesn't.
          i still feel so so srry about all this.

        • @samelight:
          Lol what. Do you know how sound propagates?

    • That's weird, I had two pairs and I never noticed the muddier/buzzy highs when turned up high. I will say though that for movies and games such as Battlefield that they were extremely immersive due to the bass and rumble that they produce. Would definitely recommend. Only downside for me was that over time, the power button was extremely finicky and would sometimes not stay turned on, that being said my other pair was fantastic until they were replaced by the z906's.

      plus vote for you, no one should be negged for an opinion, especially an opinion as well articulated as yours, but it happens.
      I have these speakers and like them, but don't love them.
      Logitech are very hit and miss across their whole range.
      I'd consider these some of the better ones i've heard.
      As desktop PC speakers at low - med volumes the quirks you mention do exist, but in my opinion are very minor.
      I've not tried them anything above moderate volume levels.
      My 5c

      • Agree. Upvoted you as well.

        The shock for me was side by side comparison. I just couldn't deny the differences. My (at the time) 8 year old has better hearing in the high end than me. (You gradually lose the top end as you get older). He said the same. My wife has hearing issues and isn't picky and she said the same.

        I was trying to show them how much better these new fantastic speakers I bought would be at the next party and ended up with egg on my face!

    • +1

      They are budget 2.1 computer speakers. You can't expect them to cater for parties outside
      Edit: somehow clicked associated

      I thought the same when I got my pair but over time, it seems like they have "burnt in". I know theres a lot of speculation going around about "burning in speakers" being a load of crap but the mids and highs sound much more crisp on my set and the bass is less muddy.

      • Small changes are not that ridiculous really. Things getting shaken looser and thermally warming, materials aging etc. The sound changing a little with use wouldn't surprise me. But huge shifts. Yeah maybe something else is going on?

        • TBH i've only noticed it since I moved into my new home so it could just be the new environment… or it could just be psychological

    • If your TV has red and white output for audio.

      Try Harmon Kardon Soundsticks. Looks good, and sounds even better. Been using it for one of our TVs for a few years now (a friend had her for 10 years and still going strong). Can be bought for $200.

      • Such an ugly speaker imo, it would be the only reason to not buy them.

        • So you're not attracted to these speakers then?

        • +1

          I agree. They look like any moment an alien is going to hatch and burst out of them. Speakers shouldn't be distracting nevermind hideous.

    • +2

      I use them on my TV, connected via headphone out.

      Great alternative to a soundbar.

      • That's exactly my setup. I bought them as an alternative to a soundbar. I couldn't be happier, 4 years with them.

    • +2

      I use them as TV speakers and they work great

    • +1

      I use them as TV speakers from a 3.5 AUX out
      Much better than the ones built into my crappy TV
      Fills the room and bass is very strong (often need to dial it all the way down lest my apartment shakes and booms)

  • Thanks all - Question, can you use the TV Remote to reduce volume? (Set the speakers to mid range, and then let the TV volume manage up and down from there?)

    • Most definitely.

    • Thats up to the TV, nothing to do with the speakers.
      If the output of the TV is controllable then yes, if not then no.
      Sometimes RCA outs are controllable, but not always.
      Headphone out's are often controllable via the TV remote.

  • I have a pair over 7 years still going strong, even slightly covered in paint lol great set for my Computer!!

  • Planning to buy these for my Gaming PC… Which one would u guys recommend? a or b?
    a) Monitor with a nice built in speakers .. (As I got a very crap monitor which is almost dead)
    b) Buy these speakers and manage with the same old Monitor ?

    • +5

      a) Built-in monitor speakers are usually very bad.


      b) Would you have a preference for visuals or sound?

      • Well, I'll pick these @ OW and buy a decent monitor then…

        • +2

          That's the way, go all out. Get both and you won't know yourself. Enjoy.

  • I really like these speakers. I use them as computer speakers so I've never had an issue with it not being loud enough.

    The one problem I have had and continue to have is that the power button is kind of "loose". I have to push the button in and then wiggle it around a bit for it to stay on.

    This is a very good price if you can get them.

    • I got the same problem. And all my friends who got the speaker also suffer this issue.
      Used to contact Logitech when it was still under warranty. However, they just bullshit me by asking me to try it on other devices or try to unplug the aux cable and plug it in again…

      • Wow, that's such a terrible response from Logitech. It's an odd switch design too and most of the warranty claims must be for this issue seeing how widespread it is.

        I was planning on opening mine up to see if dust has gotten stuck there.

        • According to my experience(though I got none), I think it should be false welding.

      • See if this helps…bit of electronic lube.

    Wasn't able to price match at vermont office works

    • Why not?

      • +1

        Have to include delivery

  • Excellent speakers, been using mine for the last 3 years for music in my room. Couldn't ask for more for $99 which is what I paid for them.

  • They sound pretty good if they get a clean audio feed - surprisingly good. Deep in the plastic "computer stuff" box in my office I found a DAC WOW and put it between the PC and the Zs. Goes loud and clean, highs are muted but they do exist. Midrange is pretty indifferent, but unlike many small 2.1s it actually exists. $99 - bargain.

    (and yes I have the loose power button as well)

    guys its THX CERTIFIED!

  • I bought these for 10 dollars from savers lol

    They working but I dont use them, i still have z5500 from 10 years ago going sick.

  • Great price if in-store pick up was available……alas, it's not, and shipping is extortionate.

    In the absence of any price matching options (Officeworks aren't playing ball) it looks like my wait for a set of these at a decent price will continue.

  • Wait how is this a good deal when they practically charge $69.72 for delivery?

    Unless someone has better luck for delivery price or has managed to get a price match from other stores

  • +1

    Today morning I bought from Officeworks and they beat the price by 5% . Price is 94.95

  • +2

    Managed to price match at officeworks Ringwood. I think they had a couple left still. Price came to $95

  • +2

    Officeworks Chadstone honoured price match as well. Probably another 1 on the shelf.

  • These speakers are great for the pc. They won't drown out a party, but they still do get loud. Honestly can't go wrong for this price
