Woke up my subwoofers!

These KEF KASA amps surprised me. I had heard they were good, but it ended up making my two in-wall subwoofers be heard (and felt) with a punch compared to before. It's as if I changed subwoofers altogether. I ended up tuning the phase and crossover knobs on the KASA for a much improved sound. Before, I had my in-wall subs on another cheaper amp, but you get what you pay for I guess and just figured the subs were doing all they could. All I know is that the bass can now be heard. The only downside is that I now have to find the subtle "rattles" that have appeared in the room due to the vibrations from the bass (to no fault of the amp or subs). Now I want one more for two more subs for a total of 4 for movies to really rumble!
