I run an amplifier that makes 5 Watts/channel, is class A and push-pull (so it has about 4.5x more usable power than SETs of the same power) in my bedroom system.
I run a set of Fritz Carbon 6’s with it. I have a sub, but the main speakers and amp are running full range. The speakers are rated 87dB. I’ve yet to run the amp out of gas.
