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?

The Wilson's go down to 20hz with smooth response. I've actually had people think I was using a sub when I wasn't. Best speaker I've ever heard. But believe me, there are times I may not "need" a sub, but want one and appreciate one. I had a Bag End Pro 18 and it went down to 8 hz by use of an electronic synthesizer, but lightening got it, so I'm looking for something to replace it. The Bag End was good. You could "feel" the room vibrating on tests CD's, but couldn't hear anything. Must be what an earthquake is like. Looking for something more musical and quicker. A class "A" biased amp would be good connected to something that could handle it.
I have a friend with speakers that don't really need a subwoofer.......they already do 20hz or so (Apogee Scintilla)

He added The Thigpen Rotary Woofer (Made by Eminent Technology) to his system and couldn't be more happy (5hz bass).

He says the rotary subwoofer is the best subwoofer in the world........looks like you can afford the best?

Edit: talked to my friend tonight for the first time in a while. He now has mbl 101 - MK II speakers, and two of the rotary subwoofers.

Make sure the sources your going to use go down below 20hz.CD players in the 80's used to say they went down to 5hz,but some newer high end CD's and DAC's only go to 20hz.
Oppo BDP-83& BDP-93 low limit is 20hz.So these won't work with analog out for movies.I no they're not hi-end though.
I had Maxx 2's and a REL studio 3. Now I have Alexandrias and a pair of JL Audio F113's. My current bass is FAR superior to what I had previously. I think it is important to know what you are trying to achieve. In short, I would get a pair of appropriately sized for your room JL subs. The bass on Maxx 2 is ample and good, but there is better out there. I found that the bass could get a little loose at times. Also, they usually don't go below 30hz when they are placed into the room as most of us do. The JL's room correction will improve the linearity of your bass, and they will go lower. After you buy them (get a stereo pair) and set them up, let me know if you still think the Maxx's were going down to 20hz.
