The Dawn system was just 2 small drivers and a sub, there was no new design or any effort put into it, and the sound was exactly that. I had a Dawn system for a couple of days, got rid of it quickly.
The Compact and the Nano, both are using new design and technology to bring a better sound to a conventional idea. A speaker on a stick will always be a speaker on a stick, unless things are modified to address the short comings, and thats what Bose and HK are doing
