7 lbs(think I got that right) diff. between DBR 12 and DXR 12. Seems everyone is concerned about weight these days.
And wattage?...
Bose talks about covering a 100 folks with a Bose Compact. HK Nano 300 talks about covering 50 folks...but, from experience, the HK Nano covers much more than 50 folks.
So, it's about weight I think.
If you don't believe that(this is a keyboard forum)..folks talk about looking for the lightest keyboard..not the best sounding keyboard...can of worms here?
