How does the KP200S handle bottom end ? I had one of the Roland KC series amps and returned it because it really couldn't handle strong low end signals. Bass patches and my analog Roland JX8P really freaked it out. But the 15" horn loaded powered cabinet I am using now lacks midrange definition. Just can't win I guess. I thought the Motion Sound amps may cover low/mid/high frequencies and I like the response of 10" speaker cones as long as the box handles bass well.
