Subwoofer to go with Wilson Maxx II's

We upgraded our demo theater from a Wilson Watchdog to a JL Gotham and have not looked back! Big room, and the Watchdog did not cut it at all. It was the passive model powered by a Classe CAM600.

Maybe you should get Wilson Thor's Hammer. :)

You would not really want a Class A amp as a sub amp. they are hideously inefficient and their virtues would not be important and their vices magnified in a sub application. You need a lot of power and what the amp does outside the bass region will be largely irrelevant.

Stans on the right track. 'd' amps are a natural for sub duty. Any switching artifacts or need for a Zobel on the output are simple non-starters.

That being said, and I KNOW it is not a match or real alternative...but my HSU will easily shake the house half apart. I can make the windows shake and all the china....in the hutch and on the walls vibrate in sympathy. My sub will cleanly produce the 16hz pedal tone in the Saint Sans symphony 'with organ'.

So, sheer low frequency output is not the deal maker. No, what you need is musicality. For movies? Why NOT replace the Bag End with another? That would be a real good place to start?
