Subwoofer to go with Wilson Maxx II's


I'm in the market for a Sub to compliment my Maxx II's. I thought I wanted a powered Watchdog-and still may. I read a review that said it may be-choke-inadequate. Never thought I'd hear anything written about Wilson's with that word in the same sentence. In it's defense, reviewer was referring to below 20hz sound in home theater. I like movies, but my main emphasis is music. Any recommendations or comments about the Watchdog?

Assuming the Maxx 11 really need a sub I would look at the REL Studio and use it in parallel with the Maxx woofer and set to the lowest possible crossover frequency. But are you sure that you really need one, what is the Maxx 11s bottom end cut off? The smaller Wilson's I have heard do not seem bass deficient.
I've heard the MAXX2 extensively, and I can't imagine needing a subwoofer with those speakers for music or movies.

For home theater use, where you have a dedicated subwoofer channel (e.g. 5.1), a sub might be called for, though I think it would take quite a sub to mesh well with MAXX2s. In that case I like the JL Audio F212. I talked a friend into one, and the F212 can produce enough clean output with a 20hz test signal to make you truly nauseous. The F212 is a monster.

But if I owned the MAXX2s a sub would be the last thing on my mind.
31.5in fostex super woofer. Would be my suggestion a good step up from drivers used in all commercial sub-woofers or bass systems.
