I recently took shipment of a pair of MMGs; they sound immaculate and I love 'em, but I would like to supplement the bass end of things.

Anyone have any recommendations for a subwoofer? Obviously I went with the MMGs because I don't have thousands to spend, so I'm looking for something pretty cheap (e.g. a few hundred dollars).

Is this reasonable, or am I just going to muck up the pristine sound of the MMGs?

I see Kilpsch makes some home theatre-oriented subwoofers for <$400, will these work OK for a two-channel musical setup?

(My amp is a Musical Fidelity A3.2 if that makes any difference.)

Thanks for any advice,
Mike
