What exactly are the inner.... objects? Speakers too?

The woofers are (obviously) in the outer cabinets. The wide inner units are actually not cabinets, rather supports and "sonic reflectors" which separate the front and rear facing sound waves for the midrange planar magnetic drivers and further inner tweeter planar magnetic drivers. There is no "back" to the curved towers. The drivers are dipoles and the sound out the rear is the same as the front. As you can see, each side has six woofers, 12 midrange dipoles and 36 (24 front facing and 12 rear facing) tweeters. The woofer towers each have their own dedicated 2 KW amplifiers. The tweeter and midrange towers each have their own MC602, one channel for the midrange and the other for the tweeters. I have bypassed the passive crossovers originally in the speakers and replaced them with the silver units in the center of the picture which are the PassLabs active crossovers. The crossover points I am using are 106 Hz and 4800 Hz each with 12 dB per octave slopes.

Paul McGowan owner of PS Audio has decided to "hunt down a primo pair of IRS V and redo the reference sound room in Boulder".

Paul says "This giant loudspeaker has a number of charms but perhaps the biggest for me is that it’s the ultimate point source."

Gary, I missed your post but I caught Paul M.'s video last week. Thanks for following up with such a detailed explanation. I read they were tri-amped but I didn't see the 2KW amps in your pictures. Are they behind the speakers?

Yes, the woofer amps are behind the woofer towers.

That was quite a series of videos Paul made. I'm sure it took a lot of preparation to produce those quality videos.

I'd dare say "intimidatingly goodlooking" should that construction even exist

Spectacular pics of your system Gary, congrats and thanks for sharing.

Great sound skull!

Always fascinated by the look of the legendrary Infinity IRS. I imagine they would play big symphony pieces with power and realism.

Superb setup, Gary.
