Hi Fred,


You Will hear a substanial difference if you feed each
amp into their own speakers.


Again, however, the increase is only 3 dB.



No it ain't :-) and the explanation for us tech oriented
types is quite simple and has nothing to do with the electrical
power, but with speaker efficiency: When you stack speakers
(notably woofers) close enough together, fed with the same
signal, power, and in-phase, they act (because of overlapping
wave compression effects) as a single cone with a somewhat larger
cone area and efficiency than two cones separated far enough.
The drawback is higher directivity, but this might even add
to the audible effect when you are in the "beam".

Good info here! Thanks, Tom!

Cheers,
Fred
