Sorry, of course 3800 CF. My house btw is about 3800 sq ft living area. lol. Sorry about any confusion my mistake may have caused.

I have a denon avr-1912 which seems to be powering the system really well for what it is. I also like the Denon app which allows me to control my reciever via my iphone. Nice.

Right now I am listening to some music with sweet string bass jazz licks and drinking a glass of wine. LIfe is good. This 'little' sub really reproduces music astonishingly well.
