uberwaltz:
I use just one ML Dynamo 700w sub right now to compliment my Maggie's.
Strongly considering adding another though.
Room can really only handle two as far as placement goes.
Would a pair work diagonally opposite each other?
So say one front left, the other rear right or?
Say, does that Dynamo hum? Frank Zappa's did.
Placement is all about figuring out where to put one speaker to get the smoothest response at the sweet spot. With more subs it matters less and less where they go. You actually want them different places, particularly asymmetrically different places, because the more different sources the more different modes and they all average out to much, much smoother bass.
With my 5, one is front wall left, two on each side wall, and they are each a little bit different distance from the corners. Tim on the other hand (noble_100) took a more systematic approach and wound up with one in each corner. His room is almost exactly same as mine, like within about a foot each way. His listening is closer to the back wall, but as I recall its dual use, he sits more to the wall for movies, further out for music. Loves it either way.
Stories like his, plus my experience, and Duke's, all agrees with the early papers (Geddes, et al) conclusion of random or at least asymmetrically located is best.
With 2 I'd put the second one diagonally opposite and spaced a little closer or further from the corner than the first one. With just two you might hear a difference moving them around. The more there are, the less it matters where they are.
