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

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.
