Presentation to the San Francisco Section of the AES, February 18, 1989
Brian J. Elliott
Floyd E. Toole
At the time of the talk I was still using a single, closed box, equalized woofer with two 12" drivers, figuring that it would take a total of ten 12" drivers in open baffle configuration to replace this woofer. I could not make room for that, though I had been extremely impressed by Brian Elliotts' six drivers per side dipole woofer columns, which rendered the most real bass reproduction I had ever heard. Later I learned from Donald Barringer, recording engineer for the U.S. Marine Band, that even two drivers per side could provide quite natural bass. Thus, I followed their lead and changed to dipole bass for more realistic reproduction of acoustic instruments.
