I have Crites speakers(similar to Cornwall). I also have subs. I can play this so loud you will cry uncle and clarity is still there. Kick drums have serious impact and will scare you if not ready. Yet this system will play vocal and acoustic recordings very nicely.
Used Klipsch speakers are easy to find. The Cornwall is 104 dB efficient. The Forte is about 100dB. Whatever you buy, if you can afford it, also buy a sub or two. This will improve clarity, impact and bass quality if setup correctly. But as others said, your ears CAN suffer.
You could use one of the amps you have on subs and one on speakers but would need a crossover
Bridging is not recommended or needed; especially with mismatched amps
