Am I understanding you to say that the fact that mine are positioned in close proximity to each other they act in a way to give 6db? And if I had positioned them say....one in front of room and one in the rear, they would be "uncorrelated" and thus only a 3db increase?
Sorry, just trying to be short and precise.
If you put the subs close together compared to the wavelength of interest, say, way less than 11ft for 100Hz, then you should measure a 6dB increase.
If you put them far apart relative to wavelength, actually, all bets are off. Depends more on the room and distances involved. This
is one of the better room mode calculators I've found.
The uncorrelated 3dB thing was a red herring, I'm afraid, due to addressing the previous post.
That's more from having two unrelated signals coming from two different points, which doesn't really apply to subs, but more to mains. Well, like I said, on average it may apply, but it's not really helpful. The room modes matter more...
