Subwoofers


I sold the first sub I ever owned, a Rel Strata III with the intent to upgrade, but now finding it difficult to decide what to buy. Given my system, GMA Europa Max speakers, and my orientation is for 2 channel audio, what should I buy? I am torn between the Rel Britannia B3 or the Martin Logan Depth. Are the Vandersteen 2wq subs as good as people say? Am I just being snobby towards them due to their inexpensive price?

Thanks.

One of the best ways (as described in some other threads) to set up a single sub (a bit harder to do with two subs) is to place the sub at your listening position and then walk around the room to find the spot(s) where the bass response is flattest. Then locate the sub at one of those places.
Nsgarch,

Could you elaborate on the term flat? Least boomy? I am expecting my sub on Thursday...I'll have details on my system and room by the weekend.

On another note I've always wondered how an independant sub interacts with phase coherent speakers. It seems logical that a sub would not adhere to the time aligned speaker, so how does one circumvent such an issue?
