Best subwoofer below 40Hz for Magnepan .7?

The title says it all! I want subwoofer bass below Magnepan's limit of 40 Hz. Magnepan will not recommend any but their own model, which does not extend beyond 40 Hz and are not true subwoofers. What subwoofers will work with my .7s?   Thanks for the personal and meaty responses on this forum!

Nothing wrong with any of the above responses, but I would recommend you get another loudspeaker rather than trying to augment the .7s.  I recommend either larger Magnepans or Eminent Technology 8b loudspeakers.  My reasoning goes that the a good sub really won't work as well or cost much less than buying a different loudspeaker.

+1drumsgreg,
Even a pair of 2w's will work wonders. And, they are built like tanks. Even my ancient pair of 2w's work as the should after 20+ years.

I have no tone controls....  dont really need them . That is until I turn the sub on.   I have a nasty room mode with a huge bump centered around 40 hz.... its bad.   I could never get large floor standers to sound good in this room because of that.   So I've used a number of different smaller speakers with a sub,  that SMS 1 really tames the peak and the two different subs I've used it with have really benefitted from it.    That said if I were buying a new sub it would have to have the same type of correction that the Velodyne Digital Drive series had  , adjustable freq, slope, EQ.

Also if you really like the Maggies, don't jump on the speaker merry go round trying to replace them , because if you like their sonic signature I think you"ll have to spend a lot more to better them.

The biggest challenge in adding any subwoofer is room integration.

I know you want to have 20 Hz response, but I wouldn't worry about that as your primary issue. The room response itself can extend or impede the behavior of a sub.

IMHO, your speakers are fine, I would keep them, and get a sub with really great room correction. You'll have a much better result than merely going with larger speakers.

When you audition a sub, you need to audition the sub and the room correction software. See how easy and comprehensive it is to use, and listen for the final results.

Since I build speakers, I do my own room correction with a MiniDSP unit, but that's beyond what most want to do. The solution for you, IMHO is to get a sub that does this for you.

Best,
