@TP123 I use the Bose L1 Model II with two Bass units with my Motif XS8 (waiting for my XF8 to arrive

I play small rooms and lounges and place the Bose behind me. I stack the two Bass units on top of each other. I go mono out of the Motif into the Bose Tonematch - you don't mention this piece of equipment. I highly recommend getting the Tonematch. It's a wonderful compliment to your system. There's a General Keyboard preset and the sound is amazing.
