Just to prove mixing subwoofers does work (at least in theory), haven't spend that much time audibly comparing them.. basically just doing the graphs.

Here is a graph of the SVS 20-39 PC Plus in stock tune, SS to 20hz, SVS xover disabled. BM setting to 80hz. In pink.

In blue is both subwoofers switched on..

Oh yeah since the xover is set to 80hz, should 80hz> drop-off quickly (like the pink line) or should it be flat (like the blue line)?
