help buying irs beta


Hi ima newbie just trying to break into the real hifi world.i have the opportunity to get the irs beta for a steal.i need some advice on what problems to look for and also wondering if the sunfire 400wpc 7channel amp would be okay for these speakers using 4 of the channels 2 for the upper panel 2 for the woofer towers

... make sure all 8 Watkins Woofers have been re-foamed ...

The IRS Beta does not use Watkins woofers, although I do know that he’ll work on them. Watkins woofers have dual voicecoils, and were used in the RS 2.5 and 4.5 models - and probably some others - but not the IRS Beta or RS1 models
My bad, though I would trust Watkins to do a great job refurbing the drivers, as I would Bill Legall at Millersound.

Those are both very good recommendations!

How big is your listening room?  These speakers need a LOT of room to sound their best. 
I formerly owned the similar RS-1b, and unless you’re a masochist I would instead get a pair of Eminent Technology LFT-8b, which employs similar but superior drivers to the EMIM and EMIT in the Infinitys.
The later High Energy Emit and Emim drivers used in the Infinity IRS speakers such as the IRS Sigma and Epsilon were quite a bit better than the previous generation, as were the IMG bass drivers vs the old polypro bass drivers. Even the Infinity Renaissance 90’s were better sounding in many respects than the old RS-1b. I can’t speak for the Eminent Technology speakers, though I note from the TAS review they are very insensitive and not completely coherent.
