Hi Phillip

No matter which PA you get, I know for a fact you will want two speaker cabinets to get the best sound.

Scott Yee started a couple posts about this. It turns out that the Yamaha instruments such as the PSR2000, 2100 and the Tyros need to be heard in stereo to handle all the effects used on their keyboards to give the fullest sound quality.

There was a discussion if one wanted to perform with one speaker whether it sounded better using the R output, the L/R, or the headphone jack. There seemed to be varying opinions about that, but the consensus was that it sounds a lot better in stereo. I have proved it to myself with my two JBL Eon10G2's.

What I see most people using for your purposes are: Barbetta 32C, JBL Eon15G2, JBL 1500 with powered mixer, and ElectroVoice Sxa100.

In regards to using one speaker, there was a post a while ago about somehow crossing the wires from out of the keyboard to one amp and acheiving about the same sound as two speakers. Apparently it was a system used some years ago for car stereos. I never heard if anyone tried that, but I know I for one would be interested to find out. I am not sure if it's safe to try it, or I would have already tried it myself.

George: That sounds like a pretty nice set-up. Could you tell us how much those speakers weigh?

Best
