it actually doesn't have to be loud. i was almost emotionally shaken with the sound that JBL vertec produced at a recent lambchop gig i visited.... and i'm not the biggest fan of kurt wagner around!. it was the smallest vertec line array rig (4 boxes per side in a 250m2 room) that had a warmth and pulpability i can still touch, like the best SETs.... and still very dynamic and fast. with all the hiss from the tube amps on stage. scary! i wish i can have that at home.
