I've been struggling to integrate a pair of Magnepan MC1s with an SVS PB12+ sub. The problem is that the cut-off on the MC1s is 80 Hz, and rather immediate, too. Unless my aging ears are lying to me, pretty much everything from 50ish Hz to 80 Hz seems directional and with the SVS to the side, this gets distracting very quickly. So I've been toying with the thought of adding a second sub in the front of the room to handle the upper bass frequencies and provide "some illusion" that this is coming from the Maggies. So my first question is whether this will work.

My second question is what are my options? I need a narrow sub so that it doesn't stick out of the front of the room too much, something not much deeper than 6-8 inches. I don't mind it being large or wide, but the depth is an issue. The other issue is that it will be connected with speaker-level inputs and will need cross-over adjustment, so that eliminates a lot of smaller "cute" subs. Finally, it needs to have some power behind it. The SVS will handle the deep bass, but I still think that 200W is the mid-bass is as low as I'd be willing to go. My budget is about $1000.

Any thoughts, suggestions?
