I am connecting Bose Accustimass Amp/Woofer/Satelites. They worked fine with my EA5 organ. Connection is with audio cables with RCA connections converted to Jones plugs to connect to the Keyboard. The connections are exactly the same that I use on my EA-5 Technics Organ and that works. It appears to be the keyboard. I am no electronic wiz but it should make no difference what kind of speakers you use, the signal should be received but maybe not the quality. To silence the keyboard speakers I plugged in headphones.
