thanks danny not had them running long but love the tweeter no compression and clean as a wistle on high hat allways a good test of a treble unit i find, just listen to the soundtrack of shaft this sorts the men out from the boys ,mid range has a see through quality normally associated with panels, nice fast bass doesnt go down that low but the balance struck is optimal i think much better to go for quality than extension ,power handling is good also as i do tend to play them at a highish level i use four monoblocs so that helps.
