Any info regarding the sound of Genelec subwoofers will be most welcome. Thanks in advance.

sorry, couldn't resist the straight line on this one, will.

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.
Thanks for the info. I've generally been impressed with Genelec monitors but had heard nothing about the subs.
