I use this subwoofer as a part of my Fun Generation PL110A Basis bundle. It's more than enough to do the the job... The sound is clean, round, well pronounced and it's just there, everywhere in the room... Where good sub-bass should be. If you turn it up, the whole house starts to quake. It's a beast for its price. The low-pass filter and phase switch is incredibly handy, you only need a sound sourse (a mixer, or an audio interface for example) and (active) speakers to start your party. Amazing!
