Mackie MR524 Active 2-Way 5” Studio Reference Monitors $478 for The Pair Delivered ($239 Each) @ Sounds Easy

Ok these are powered studio-monitors.
Standard price elsewhere $559 Delivered for the pair. RRP $638.
If you are looking for the coloured sound and/or ease of use of conventional powered speakers you can stop here.
(These do not have Wireless audio built-in. You will get the best sound/signal level with balanced XLR or TRS cable connection.)

If you know what you are doing and have the ability to set these up properly for mixing and/or prefer a flat sound signature, you could consider them even for casual listening with the correct dac/pre-amp.

Mackie MR524’s for $478 for the pair delivered (this deal).
Mackie CR5’s (5 inch) are $458 for the pair at JB HiFi (not available for delivery)
and around $389-$400 for the pair delivered at other stores.
(*worth noting CR series seems to have a build quality issue where heat from the amps damages circuits & switches begin to malfunction + loss of sound).

I have never owned or listened to these MR524’s.
Z reviews said they are similar in sound to JBL LSR305.
So I would say great wave-guide, flat response, with a tiny bump in the low-end, and slightly better sound than LSR305’s due to Class A/B amps (especially at lower volume levels as mentioned by Zeospantera).
For mixing, have heard they are particularly good for electronic/dance music.
Would be a possible option to the LSR305’s for casual listening (the JBL’s seem popular for casual).
They are Bi-amped, Class A/B amplified so I suggest avoiding running them extremely loud at maximum volume for long periods as the Amps produce more heat than Class D amps.

*these will only be of any use if you know what the compared speaker sounds like.

Based on the video Mackie’s sounds similar to JBL but more open/transparent high-end,
Yamaha flat overall from mids-down right to bottom of the low-end with known sibilant high-end.
