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

Timlub

Back in the day when I first began to use stereo subs I also used Marcof inner connects the ones that were black. I also had the latter blue ones but the black ones sounded as if they had less phase shift so I sold those off the blues and stayed with the blacks. The battery powered pre-preamp was also excellent and worked well with my Accuphase AC2 and the Denon 103d and 103c.I also stopped by your location in the St.Louis area.
Thanks for those products. Tom

Thanks Tom,
As you might expect, I've got quite a stash of Marcof innerconnects, I also use our speaker cable. We experimented greatly with litz, different braids, wire guage etc. I am using some that we never manufactured, but they are closer to what you have than the blue (se) models. Ed still says he still has PPA-2 head amps. They were a significant step up to the PPA-1 that sold so well. I agree completely about stereo subs, I just haven't heard one crossed @ 40hz that was directional. You may be one of the select few that can recognize this.

"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.
