Bernie if a splitter means Right and left channels from the keyboard going into a splitter to a single channel (one wire) into the Bose --- I did not find any difference. Gary said that the keyboard does that internally when going out to the R/L channel.

But two Bose speakers placed on either side of you – aaaaah, now that has to be something. I used two Eon 10” powered speakers one on each side of my Kn7000. It sounded good and looked great.
