I have custom designed subwoofer systems that I designed and built embedded in the wall behind my Maggies. I am well satisfied with results. While this design may be impractical for most people, (eg: apartment dwellers) some of the concepts I used may be relevant.
1..Every speaker should have its own subwoofer. This might mean three if you have a multichannel rig. Five would be overkill.
2..A large area of SW cone is desirable. In each of my three subwoofers, I have a 15" and a 12" driver, stacked. The idea here is that the Maggie is a large area low excursion driver, and the subwoofer should work the same way. A line array of four 10" SW drivers would be a good choice.
3..Locate the subwoofer directly behind the Maggie(within 2 feet or less), and raised off the floor so that its center is halfway up the Maggie (centered). The idea here is that the subwoofer "plays through" the Maggie. Good "integration". I have a hunch that the subwoofer works in part by absorbing the Maggie backwave rather than projecting its own sound.
