I surfed into your site on a search for Bose L1 stuff. I am a guitarist and singer, and I play a Parker nylon string guitar. I just bought a Roland AC-60 which works great in my small bar gig. I auditioned a Bose L1 system at GC recently, and I was really impressed. The Taylor nylon string guitar sounded as clear and transparent as on any system I've heard. Very accurate reproduction. We also AB'ed the sound with and without subwoofers. There's an only slightly detectable difference, on the low (80hz) E. I know you keyboard folks need lots of good low end, still pretty impressive. We tried a duet with electric bass and 2 subwoofers, again great sound.
