Anyone know how much weight my keyboard will lose if I remove the speakers from my Sx 900 keyboard?
John C,

I've thought about doing that to a keyboard myself. If you find out, I would like to know. I would also like to know if it works normally with the speakers removed, or gives some kind of error on boot-up. (To determine if the speakers are in good working condition, the board may check the circuit for an electrical resistance. If so, you could still fool it by inserting a component in their place.)

Teds, I removed speakers from a Yamaha keyboard many years ago, no problem. I do not use the keyboard speakers on a job ---

I use one or two Bose L1: I want to hear what the people hearing. I installed outputs to feed the speakers I removed. -----

I am 92 years old, and weight is an issue. When I tried to lift the Yamaha Sx 900, it would not move. It weighs 26 ½ lbs. my 92 years was tested.
