What speakers play the loudest cleanly ?

Klipsch...LOUD!

For a non-horn type design, I would say that the larger ATC are the loudest and most dynamic speakers you can find. The ATC 3" midrange has a much bigger magnet than 99% of woofers (just to give you an idea). ATC woofers also use heavy magnets and have some of the largest Xmax I know of. Watching Top Gun with ATC is like being there on the deck of an aircraft carrier...either you need ear defenders or you need to turn down the volume to a comfortable level. These speakers are not suited for a condo.
