PS Audio have announced they are selling their Infinity IRSV speakers.
One of only 58 pairs ever made. Price in the $70=$80K range - a bargain
methinks.
Further particulars here: https://www.youtube.com/watch?v=oXU9xIgv_DI

Thanks! for sharing- Mike.
This particular Loudspeaker System has to be heard in order to believe.
And yes, the owner will need quite a Room.
The first 7 minutes of the linked-below video provides more information about these beasts.

GMAFB. Value and worth are in the eyes and ears of the beholder. To those people the speakers age is not relevant.
Dogmatists, of course, will disagree.

Nearly every time, the woofer surrounds had become porous or even just half there. Beyond "see-through."
Ah! That's why the bass is not as full as you remember.
Now, if PS Audio had been able to source replacement drivers and replace all the worn parts, OK!
But if that is not the case, buying a "bargain" collector car is usually marrying a money pit.
I think it's the same for loudspeakers.
There was a pair of small Wilson floorstanders. When I removed the grill, about half a cup of black dust hit the floor. It was what was left of the woofer surrounds.
For $75,000, PS Audio can give the happy new owner a 5-year guarantee.
IMHO.

"IMHO" Indeed. LOL

Due diligence on the part of the buyer is an obvious given.Do you have such little regard for Paul Mcgowan/PS Audio? Do you think that Paul will not inform potential buyers of the condition of the speakers?
Did you watch the video linked to in the OP? The IRSV woofers have been replaced with new modern woofers. Watch starting at 1:30 of the OP linked video where Paul mentioned the new woofers.
As I mentioned in a previous comment in this thread:
"Simply "rebuilt" is not the appropriate description.
This pair of IRSV speakers have a new custom outboard crossover design blessed by Arnie Nudell (as mentioned in the video) as well as the original woofers replaced with modern woofers (sans the active servo system) and with new woofer amplifiers as previously mentioned by Mike K. The EMIMs have also been rebuilt."
Additionally, information on the loudspeaker, including restoration/rebuild and modifications, is available for all to view at the PS Audio website.
Your previous comment "Does that video make the speakers younger??? Criminy GMAFB" does not mean or imply "For $75,000, PS Audio can give the happy new owner a 5-year guarantee." As I stated before, regarding the $75,000 valuation, "Value and worth are in the eyes and ears of the beholder. To those people the speakers age is not relevant.". But, you are free to go to the PS Audio website and YouTube to view information regarding the speakers, read up elsewhere on the historical context of the Infinity IRS V loudspeakers, including rarity, and give your valuation. I'll give you a start, the MSRP of the Infinity IRS V was $45,000. And, I think that only 58 pairs of IRSs, inclusive of all versions, were made.Caveat emptor is a given, but, the bottom line is still that the value and worth are in the eyes and ears of the beholder/buyer. Dogmatists, of course, will disagree.
"For $75,000, PS Audio can give the happy new owner a 5-year guarantee."Hmmm.
Please inform us of how common a "5-year guarantee" is for similar used audio gear, with referenced examples.
P.S. As should be obvious to all, Paul's Infinity IRSV are not just people's "beloved old loudspeakers".

I blanked on the new woofers.
Of course... all those little planar panels... what about them?
Anyway, I still think that Rockport speakers with SOTA TPCD drivers is the better way to spend that kind of money.

Wow I figured Paul would never sell the IRSV. So, this raises the question did Paul find something better? Or maybe it just looks bad since PS audio is making speakers now and the owner is listening to Infinity's and PS audio speakers.
Those IRSVs are what, 30+ years old?
They look like a Money Pit to me.
If you want very tall radiating surfaces, IMHO you should investigate Sound Lab electrostatics.

Heard different versions at Sea Cliff in the 1980s and indeed they were quite impressive in some regards. Bandwidth, check. Dynamics, check. Lifesize image height and soundstage, check. Unfortunately, the woofer towers sounded as though they belonged to a different speaker.
My first disappointment with hybrids blending planar dipoles with dynamic woofers.
Irecall being told by people I respect that the biggest problem with the IRS speakers was the transition from the woofer towers to mid range planars, that the midranges didn't go low enough with power and the woofers didn't go high enough so there was a significant dip in that range.
the challenge is more than a frequency response aberration that equalization might arguably *fix*.
It pertains to the difference in character between the monopole dynamic woofers attempting to blend seamlessly with the dipolar EMIMs.
I had IRS Betas, which had much larger L-EMIMs and they still didn't really go low enough to blend correctly with the woofer towers. They wanted 115Hz (or higher) and the woofers wanted 80Hz (or lower).
There wasn't a hole per se but there was a clear sonic mismatch between the two driver technologies.
Down at 80 Hz and below the woofer tower should be largely omni-directional but at 115Hz it was too directional and then you have a radiation pattern mismatch.
I also had a pair of Genesis VI speakers with metal cone woofers front an back...that blended seamlessly with dipole midbass coupler and dipole dome midrange (amazing driver). Tweeters front and back completed the dipole radiation pattern. A very good speaker, actually, as was the Genesis V.
and each driver has its own 1000wpc amp. Per the video.

for which I found starkly dissimilar to blending with the dipolar EMIMs.
The original (Bascom King designed) amps were 1.5 kW each. Power is not the challenge.
Simply "rebuilt" is not the appropriate description.
This pair of IRSV speakers have a new custom outboard crossover design blessed by Arnie Nudell (as mentioned in the video) as well as the original woofers replaced with modern woofers (sans the active servo system) and with new woofer amplifiers as previously mentioned by Mike K. The EMIMs have also been rebuilt.
Per PS AUDIO website (link below):
"Time for an upgrade to the bass system with a more modern approach. As much as I might want to preserve the IRS in its original state, I recognize it's not a museum piece.
Our senior speaker engineer, Chris Brunhaver, pulled all 12 of the IRSV's original woofers out and replaced them with a more modern, beefier, lower distortion, higher excursion, version. Once out of their box, I was reminded of just how old, tired, and lacking the original woofers are: cheap stamped frames, small magnets, short coils, conventional spiders and surrounds. The only exotic element was their graphite cones. Back in the day, they were "the bomb". Over the years much has changed.
Designer Arnie Nudell was never a fan of spending money on fancy woofers. In Arnie's view, a woofer that met minimum specs was just fine because whatever its weakness might be, it could easily be corrected with the active servo system. He and I fought endlessly over this philosophy. I wanted the best-built woofers possible so the servo system did next to nothing. Arnie felt it was a foolish waste.
I am not here to suggest either one of us is right or wrong because, unfortunately, "The Arnold" is no longer with us to defend himself.
That said, this all new woofer system is nothing short of breathtaking. Holy crap! 4,000 watts of amplification per side (compared to the original 1,200 watt amps), massive cast frame baskets, long-excursion linear coils, oversize magnets, super compliant spiders and surrounds, coupled to a stiff aluminum cone. Distortion levels sans servo are below 1%, a figure not even possible with the full servo and original woofers."

who enjoy hearing The Bass , that pair should do even better!
You need quite a room for those bad boys!
