I have been using various speakers for band and we have tried other brands and set ups including the Bose systems and what we have landed with is the QSC K10's they can handle the full spectrum of sound from bass, synth, drums, backing tracks, and Guitars and sound amazing. We use the PreSonus Studio Live
16.0.2 Mixer and we just sound great. The QSC K10's really made a huge difference in the way we sound and play. They sound clear, detailed no muddiness and the fans love the way we sound. The ease of the use is great too and can be used for a solo gig with a iPod hooked up to play backing tracks. Great speaker and for our use just the best we can play louder with out feedback and the clarity of tone is just something you have to experience to understand. We got a great deal from www.hsprosound.com The regular price was $749 and we got them for $699 each. The guys at www.hsprosound.com are real pros. Thanks HS and QSC.
