OK all you Infinity RS 1A/1B Beta speaker owners..

Well, here's a link to the RS1/1b tech sheet I put up on my website. Please feel free to download it if it may help you.

It appears there is a variable cap in the signal path from the inputs of the xover and the mid/high outputs. I'd think twice before I ran my RS1x mid/tweet towers directly.
Have a look at the schematic for yourselves!

I enjoyed RS1x for many years, since gone on to IRS Betas. One nice thing with the Betas is you can run direct to the mid tweets, allowing me to utilize balanced equipment!

I hope the tech sheets will help.

Thanks to all.....especially the Tech sheet......I still have some questions but have e-mailed some of our "audiogoners"......my big question is what Beemer said about the need for a "cap".....some say yes and some say????
Anyone have comments that are first hand?

Great appreciation to all!

I been using my RS1b's through the crossover without any modifications for years,and I think they sound fantastic,and look great(the wife polishes them once a mounth).I run Mono blocks for the Bass columns,and a Tube amp for the mid/twt columns.One of these days I will run Mono amps for the Mid/twt columns like mabey a pair of Aragon/Palladium MK2's to finish out the system.As a matter of fact I just had the crossover opened to clean and tighten
the insides up.Will always keep these speakers.

You are correct about the need for caps on the RS 1 and 1 B, you can have caps installed, but I would not recommend this. The real deal is to rebuild the unit to modern specs. I would start with a different unit and have it redesigned, or rebuild the unit from scratch. I would use XLRs rather than going single ended. You can buy these speakers at bargan prices today, but keep in mind they require top quality amplifiers and something like Brytson 7Bs for the bass and a Krell KSA 250, or Threshold T 400 would be great. For that money, it only makes sense not to have a dated electronic crossover/ bass enhancer in the path?

Do you (ladycharnet) know of a real good tech (tri-state area NYC) that can do this type of work? I would love to put in a new power supply into my servo crossover.
