Infinity Epsilon/ Beta speakers-- Classsics???

Hello, I am also an Infinity enthusiast and have a pair of Renaissance 90's that I absolutely LOVE- they are SUPERB speakers!!! If you look around and can find a pair for approx $1500, they would be a Great buy. Have you seen the site: www.bobbsyhred.com/infinity.html ?? I also very much admire the Quantum & Q models Infinity made back in the late 70's- I have a pair of Quantum 3's, Qb's and Qe's and they are all great as well. Also- the whole thing about power can be a bit exagerated- well, as far as the Ren 90's go anyway. I am also a vintage Sansui enthusiast (www.classicsansui.com) -> I have quite a few Sansui amps & receivers in my collection- and all of them can drive the Ren 90's - JUST FINE. I had a new Odyssey Stratos amp (www.odysseyaudio.com) and sold it- it was nice and all- but didnt offer anything more than the Sansui hi fi gear I already have.

I have owned the RS-1B for a long time and I had used Audio Research gear and it sounded very good. Several years ago, I bought a used pair of IRS Betas. These speakers put out a lot of bass, in fact too much even with the proper adjustments, it was just too much. I got an Accuphase D28 digital equalizer and it was magic after that. I am using an older pair of Krell KMA-200 on the bottom and Sonic Frontiers Power 3 for the top.

I have refoamed all the woofers recently. It was not particulary easy to do, but the prospect of having to spend $165.00 each or a total of $1320.00 easily made the decision for me.

If anyone is considering buying and IRS Beta or RS-1B, one does need to check the foam surrounding the woofer for cracks.

here is a link for old Infinity speakers..

The Infinity Beta is the best speaker at a reasonable price for super full range sound. The Bass uses the same 12" drivers found in the orginal Kappa speakers. The main thing to keep in mind is these speakers need a great deal of power on the bass! Infinity claimed the IRS had a 2000 watt amplifier built into the bass. That being so, I would say that something like a Bryston 7B would be the least power I would recommend.
I always liked the RS 1 and 1B better for the midrange and highs over the Beta and the Beta better for bass. Some have discussed using two bass networks, rather than one, but I think the 12" woofers in the Betas make the difference.
Both speakers are great and still today, are among the best speakers out there. The IRS is better; if you need something more than the RS1 or IRS Beta, but can't afford the IRS you can build something in between and that is where the real excitement for me begins!

i have a set of infinity IRS Betas, and the foam ring that attaches the woofer cone to the speaker has turned into dust. does anyone know who might repair them?

thanks
