Scott, maybe you should wait until you get the Motion Sound KP100S. I just spoke with their technical support, and the man, Joan (I think), told me that the KP100S makes a great monitor when it is set up 3 feet behind the musician and propped up two feet. He told me that the system spreads the sound around 180 degrees and sounds fantastic. I asked him about the bass response, and he told me that the speakers are rated to go as low as 50htz. He told me that two 8" speakers have the same surface area and thus the same depth as one 12" speaker.

But when I asked him about this replacing my JBL Eon10 G2, he cautioned me that the JBL speaker is very efficient and high quality, and that the two 8" speakers might and might not be able to get the same depth and volume. He told me that if I needed more punch I could replace the speakers that come with the amp, but that the amp was more than adequate for small clubs.

I am using a keyboard with built-in speakers, so I don't need the KP-100S as a monitor.

I'm going to get a subwoofer for the KP-100S, so if I'm playing for a larger room I can always have enough bass.

Good luck
