[Vintage-Audio] Update On AR-4 Info

Tue Jul 8 10:33:00 2003

Well, Rudy's example sure makes sense to me.  I have always set up stereo
systems the "correct" way, but do know if you hook one speaker out of phase
with the other you certainly lose a lot of information.  The last years, I
have been working with computer and communication speakers, and there are
not a lot of bass drums in the sounds!  Hah.    And, too many years in a
stereo sound room have pretty much wiped out my high-end reception!
Duane, the speakers that plugged in the wall, would those be the
electrostatic speakers you are talking about?  My stores were dealers for
ESS, which was first known for their electrostats. As a matter of fact, I
believe ESS originally stood for Electrostatic Sound Systems.   They were
nice huge speakers, highly ineffecient and not for the rocker, in my opine.
ESS later became famous for the Heil tweeter system incorporated into their
bookshelf and floor standing speakers.  I had 2 sets of those in my home.
