Yes, they will "rock", or play at high volumes with a modest powered amp (tube or solid state) but that is not what they are designed for. They are a very refined speaker with great tone, clarity and detail. Bass is flat to the mid 30's and dips into the upper 20hz area. If you are looking for a speaker with lots of "slam" for the same money, I would lean towards something in the Legacy line. They are very efficient, and dig deep down in the 20hz area. They have multiple 12" or 10" woofers that move a lot of air. Best driven by solid state amps when "rocking out", but your VTL should have a pretty good grip on them.
Reference 3A Grand Veena, can they rock?
I see a lot of glowing reviews about these speakers, but not much mention of dynamics or how loudly they can play? Can they do justice to hard rock? I heard the Decappos years ago and thought they were pretty good for their size. How big do the Grand Veenas play?
