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

Just a second pair of interconnect from the pre-amp direct into the power-amp of the high-mids tower.

This means that to able to do this you're pre-amp must have a second pair of pre-outs

I beg to differ - but I used to own the Beta's and I ran the mid/tweeter panels direcly from pre to power, bypassing the redundant Crossover. The Beta crossover did not have a high pass filter feeding the mid/tweeter amp - it only had lower and upper limits intended for the bass panels. The ribbon panels had their own internal passive crossovers, which prevented any deep bass information from being passed on to the EMIMs, EMITs, and the SEMIT. To this day, I never understood the design of the BETA crossover, it would have made much more sense to route that high pass filter to the mid panel outputs - I can't speak for the RS or RS 1B crossover. Just my two cents worth.

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.
