I used a Bose L1 model II at a lawn party last month and got great comments from people that had heard me play before (with my yorkville pa w/sub). The sound was crisp with great sounding guitar, vocals, and amazing bass (I only use realtracks). Last week I went into Easy Music in Honolulu and plugged in my iphone with some of those tracks into the L1 compact. I was able to overdrive that fairly large store with excellent sound, so it has plenty of power. I'm thinking about getting two of them to run in stereo, as I like a stereo sound. I use a small Alan & Heath mixer with FX on the Bose.
