the HK system has it's limits power wise but two can easily handle 100-150+pp and although it sounds great I couldn't use it at many of the bigger venue rooms I perform at where you need bigger speakers for usually 350-400pp. As far as a comparison to my old Bose L1 system which I never liked...I'd certainly rather use the two HK's,... first off it's Stereo and the coverage of using two HK systems is certainly has a more quality sound IMO then one MONO Bose L1 or Compact system. You just have to use it live on stage to understand what I mean.
