Many home sound systems today simply sum the bass energy from both
channels into a single subwoofer anyway. It doesn't matter where in the
room the subwoofer is located, because our ears are too close together
to detect a phase difference at those frequencies.
I think our home stereo is up so that the amplifier's speaker output
goes to the subwoofer, then the subwoofer splits the output to each
stereo speaker while filtering the highs out of the subwoofer signal and
the lows out of the speaker outputs. Our receiver doesn't have a
separate subwoofer output like newer ones do, I guess.
