Powering Old Infinity towers with Peachtree 125 sky-- with analog EQ

Running the loudspeakers in parallel might work but I'd be concerned about the low impedance at that point. Maybe call Peachtree?

You might consider wiring the speakers in series, all else being equal.

It depends on how you wire it. In series there won't be a problem.

RSIIIa easy to drive..  Try them alone first.. 

I have a few RSIIbs, RS4b and 2 pairs of the first Infinitesimals. I've always been an early RS Infinity guy..

Thanks for the response.. RS111 sound OK.. Big room has poor acoustic qualities, too much glass, tall ceilings etc.. Although I am "soundproofed out" with all necessary dampening, still in need of analog EQ which cant be hooked up with sky 125..Digital EQ programs just does not cut it. Peachtree corporate tells me to pony up for a better amp! Any suggestions?

I'm guessing you are talking about vintage Infinity RSIIIs? RS-3s, not RS 111 (one hundred and eleven)?
