What to drive my RS 2b's Infinity


I currently am trying a bryston 3b on the low end
and a SUMO nine on the mid-highs

I feel it is a bit underpowered.

Any experience out there with these speakers ?

Thanks to everyone for posting.
Due to sourcing equipment and the bargains to be had locally - I am going with bryston 4b on the bottom and
2 krell kma-100mkII on top. I will keep you posted on how they sound( I don't have everything in yet ).
I have problem find a user manual to connect my rs 1b which I bought them used. Anyone can help!!!!!!!!!!!!
For years I drove my RS-2B;s with a Bryston 4B on the woofers and a conrad-johnson MV-52 on the mids and tweets, with an ITI parametric EQ replacing the Infinity unit.

I have been collecting some gear so I can do some serious mods to these speakers. I am going to add four more EMITS to each one and run them as triamped line arrays, using Bryston 7B NRB's on the woofers, the c-j MV-52 on the EMIM's and mono'd and modded Dynaco Stereo 35's on the EMITS. The crossovers will be Bryston 10B-LR's. Infinity guru Bill Legall has reassured me that these mods should be well worth my effort.
