my existing room is 12 x 12...this sub looks ridiculous in there. I am seriously considering calling Dave Ellerton tomorrow to see if he can do something to get me the VTF 2. It looks like it will be plenty and with the variable tuning, and it's smaller size, i am wishing I got that one now. I had no idea these Hsu subs were as big as they are. If I can do this easily, without losing any cash on shipping etc, I will exchange it.
As for the sound, i can't really tell yet as I have to screw around with it. i am stuck leaving it where it is now, between my left speaker and the TV, against the wall. Actually is better there than on the other side of the left speaker in the corner (at least my old one was) because it's too boomy in the corner and I wanted to seperate my two fronts more for a better soundstage and better seperation... I did get some small carpets from a local carpet shop to put under it as i have hard wood floors. That made a difference...a little tighter now. I also stuffed one of the ports with a towel and did hear a loss in volume loudness, but heard a deeper, punchier sound with music.
I actually have a question if anyone can answer: If you are using the crossover on the sub and have the crossoverswitched down to "in", why do you still hear a difference sound when adjusting the crossover frequency on the Denon.....am I crossing it over twice??? Anyways, my system sounds much better and more evened out since I started using the crossover on the sub. I can fine tune it better than the Denon does going up in 20hz increments...
