The article is out of date. Today, receivers and processors route all subwoofer information derived from all channels that are specified as small and including the LFE channel to a common mixer. This information is at a frequency below the crossover setting and as such is not localizable by the listener. When fed to a subwoofer it will in effect make all speakers "full range".

Since the information is mixed on a common subwoofer output, it can be fed to a single subwoofer that can be placed in the best possible position in the room for an even response and it can be equalized to compensate for room resonances. If you attached subwoofers to rear or surround or center speakers the connection will not be equalizable (is that a word?).

The article makes statements such as this: "Unfortunately, the product you really want for adding bass to the front and center speakers in a single subwoofer, to the best of my knowledge, doesn’t exist: a subwoofer with three input channels.
OK, that statement alone should make you stop reading... sheesh.

You make very good points. When I think about it, 4 individual subs all being unequalized and pounding at the same time would sound terrible. I'm not going to even bother trying it now. But lets say for arguments sake, all 4 are flat to 20hz, any difference?

Thanks for the input.
