Multipel Driver Subs

The biggest problem mating mono-pole subs with di-pole speakers, is the way that each interacts with the room.

Any "good" sub will mate well with Magnepan speakers as long as you cross over at 80hz or below.......I use 65 hz with my Apogee speakers.

"Quick" has nothing to do with it..........the Maggies are no quicker than any other good speaker on the market (if they are, they are playing the wrong freq's)

Your best bet would be to use di-pole subwoofers with the maggies?

The JL Audio Fathom F212 was the best match for my Dali Megaline. The Megaline uses a seven foot dipole ribbon (per channel) that operates from about 1000 HZ on out, similar goals of dispersion and speed as the Maggie dipole ribbon design.

The JL subs are a superb match for my twenty four 6.5" woofers which are quick and rear ported. The subs are absolutely invisible musically, except I have very low bass previously missing.

I run them as a stereo pair in my system, I bet the JL would be a super match for your Maggies too. They should cross low as Dave and I have both suggested.

Rel's, Velodyne and especially Definitive Technology (one active and 2 passive drivers) match well with Maggies.
