Is Bass Non-Directional In A Two-Channel Rig?

"You will increase the sound stage image size by roughly thirty percent with the proper implementation of time aligned stereo subs." - Theaudiotweak

Where does the 30% figure come from? There must be some science and math associated with such a statement.

I've always assumed that 45% of all statistics are made up on the spot, you can quote me.

Several first time visitors when hearing the system with their eyes closed were asked to point in both directions where the sound stage ended..it was a foot or two beyond the main stereo pair. When asked to do the same with the same recording the same volume only this time with the subs on.. they pointed with both hands in a plane that was parallel with the speakers,extending from wall to wall 21 ft. This physical description came from one person at a time having two eyes and two ears and two arms. There is also an increase in stage height as well as an increase in image stability between the stereo pair with the subs engaged. Tom

Off the rails again.

Rather than stuck in a box I will accept "off the rails" as a compliment. Thanks Tom

Have you done that same experiment with a single sub places behind the listening position? It makes sense that that having more bass will better "fill" a room and this is what I think you're describing.
