The legendary budget passive bookshelf speakers by Pioneer/Andrew Jones.
Very popular on audiophile forums. I believe these are discontinued, somehow Kogan has stock?
RRP $479 on Kogan.
Use 14 day Kogan first trial for free delivery, can cancel subscription afterwards.
Note that these are not powered speakers like most of the edifier's on sale. These will require a speaker amplifier to run, and speaker wire to connect them.
