Several years ago, I had the opportunity to double the audio output of our Rodgers 990E (installed in the chapel and used primarily for weddings, funerals, and occasional services). I had two extra speakers already at my disposal - an Allen gyrophonic projector and a Leslie (don't ask where I found these, but they were FREE). I also had plenty of Rodgers speakers to work with, as the original installation contained three separate antiphonal chambers, none of which worked well because of their close proximity to the folks sitting in the balconies. I removed all of the antiphonal speakers and utilized the amplifiers, but ran the audio signal to the Allen and Leslie speakers. I was absolutely shocked at how much better the same stops sounded when played through the new speakers. My guess is that each "brand" of speakers has its strong and weak points, often showing up in particular frequency ranges. By mixing the brands, each one seems to cover the other's weak spots. This experiment was so successful that I purchased a second Leslie and found another free Allen speaker - so my organ now has four Rodgers manual speakers, one Rodgers P1 pedal cabinet with a 30" speaker cone, two Allen gyros and two Leslies! I bought a few double-pole/double-throw switches from Radio Shack and wired them to the four "rotating" speakers so I can play them stationary, slow speed "chorale" or fast trem. This is in addition to the regular tremulants on the Rodgers. The point of all this: I recommend mixing speakers if that's an option. It really improved my 990. You might even look into buying some new Rodgers tone cabinets, as they are vastly different from the old analog speakers. Tom Alderman Roswell, GA.
