Agreed, and ime another benefit is significantly smoother in-room bass response. "Smooth" bass is "fast" bass because it is the in-room peaks which take longer to decay into inaudibility. Rooms effects are far greater than the variations between different high quality subwoofers one might choose between, so addressing the room interaction issue is addressing the thing that matters by far the most, from a sound quality standpoint.
@quickjack1234 again:
"Multi-Subwoofer Set Up & Calibration...
•Place your subs wisely-in home theater rooms, nothing is more important for achieving good bass than proper placement of your subwoofers and listening seats"
Agreed, and I’d like to suggest a distributed multi-sub placement strategy.
I suggest deliberately asymmetrical positioning such that each sub is interacting with the room in a significantly different way, and the sum of their multiple dissimilar peak-and-dip patterns will be smoother bass throughout the room. The following is one possible placement strategy, drawing from Earl Geddes’ thoughts on the subject:
Place one sub in a corner; place the second and third subs along each of the two walls opposite that corner; and if there is a fourth sub, place it not too close to any of the others, and not symmetrically with respect to any of the others. Bonus points if you are able to elevate one of the subs closer to the ceiling than to the floor, as this distributes the bass sources in all three dimensions.
Two subs intelligently distributed are smoother than one; three subs intelligently distributed are smoother than two; and so forth.
