The Music Room has a mint pair of Infinity IRS Beta's for sale at only $13,999!

Admittedly, that's a lot of poundage for $14k.

But SQ-wise, how do you think they compare to current alternatives?

(My guess, having not heard them for 20 years, is that the bass would still be impressive, but the mids and highs maybe less so)

With me I'd admit it could mainly be a nostalgia type thing, a pair of speakers I almost robbed a bank to own. :)
But I'm believing there's still something to the big picture engineering of these speakers in the whole that made Paul McGowan go to the extremes he did to get a pair of IRS V's as the PS Audio's reference system. I read he did get together with Arnie Nudell to update the passive crossovers with modern components. I also swear I've read somewhere that they were also working on a digital version?
Bottom line is they sure are purdy. ;)

I was tempted at one time to think about maybe possibly changing out the caps in my speakers, but I wasn't able to get the back off, and then got laid off (2002) before I could steal a raised-computer-floor-tile-suction-grabber which I thought would do the job, and now, I don't seem to think about it any more.

They're the three on the right front corner. Scale: the crossover/bias panel is 22" x 10"

On one hand I'd love to recreate my old IRS2's days, but OTOH I remember how many EMIT's and EMIM's I repaired or replaced during that period (late 1970's - mid 1980's) for myself and others. They seemed to get blown frequently despite the overload protection and added fuses. The eyelets for attaching the planer traces to the connecting wires frequently separated from the traces. A fairly easy repair but man I got tired of doing it.

If I hit the mega million lotto Ray we'll get together and play.
Going to a DSP crossover with DRC might be really interesting.

Peter, Welcome to the forum!
I know I could never afford them, let along house them but I can dream.
I would like to comment that it is dangerous practice to post phone #'s and emails to a forum. Better to state what your selling and ask interested parties to PM you.
