Who actually heard the Infinity IRS?

I've been looking at the very high value Arion speaker and it's called to mind a vintage speaker, the Infinity IRS.  They are not the same speakers, but honestly I never actually got to even see an Infinity IRS in real life, let alone hear one.

I'm wondering if anyone has or even owns a quad (pair would be wrong) of them could talk about the sound quality and compare to anything today.

... we had a customer who owned them. I recall he blew out the mid size ribbon drivers frequently.

There are no ribbon drivers in the IRS system. They're planars.

They are aluminum mounted on a substrate. Not true ribbons but I believe Infinity called them ribbons, IIRC. Or EMIT and EMIMS, Electromagnetic Induction Tweeter/Midrange.

Infinity was careful to not call them ribbons, because they'd used ribbons in some of their earlier speaker models (such as the Servo-Static) and those drivers were problematic.

i worked at Infinity dealer in Ohio, displayed everything but IRS. I had a few occasions to hear and tweak setup, mostly with CJ Premier electronics and SOTA / Souther / Dynavector Diamond front ends. the towers were maddening to properly integrate…perfect on one recording, abysmal on another….

One customer with a massive LP collection said “ i gave up listening to my collection, now i just listen to whatever LP HP recommend ( the late Harry Pearson of Absolute Sound fame, who i believe took his IRS to the grave…. )
