The plan:

Powerful Sub for both Music and HT

The cabinet:

The cabinet is around 2f3 3/4 MDF sealed. I am using PE's 250w plate amp.

The results:

Tight and low. This sounds great I really enjoy listening to this sub. For music I turn the level down quit a bit it will over power my mains. For HT it sounds great. I had to re-play all my DVD’s again. There were low freq sounds that my old sub simply did not play. The only problem I have is that when I really push the sub on a bass heavy DVD the 250W Amp will clip. But I have to admit this sub is pushing very high levels when the amp clips.
