Yes. Boom Boom Boom. Not much else. I cant remember the model #, but it was the one with 1 active woofer and two passive. There were two in a fairly small HT room and it was not terribly good. Very 'one notey', kinda fat and not in control. I believe it to be a function of passive woofered subs in general.
Genelec's active monitors on the other hand are rediculously good, especially for HT.
BOOM!
