While the Dunlavys are no slouch, they don't compare, at least in respect to volume capabilities, to the larger ATC (200 or 300 model) powered speakers. They're designed for pro studio use and are highly accurate.
Loudspeakers played LOUD
I listen half the time to really loud music. I chose the Dunlavy V for this reason. They are very accurate and can handle high volume. Are there any better?
