Keep in mind I have a 8' ceiling, 7' wide, 9' long room. Heres what it kinda looks like (hopefully the picture helps). I didnt have room to put where the speakers would be, and yes the door is at the foot of my bed (where I would be listening from). (7ft wide) ___window___ |----TV---sub-| |--------------| |--------------| (9 ft long) |----------desk| |--------------| door___bed____| Neighbors I would mostly be using it for HT, with maybe a little music. I live in a sort of a townhouse place only instead of 2 people its 4. So on every corner of the building is a home, and I've already have received complaints using my HTB 505 sub (my new sub obviously is going to be more powerful so I just wont be able to use it to its full potential until I move out). Anyways, I'm also thinking long term, since I plan to eventually move out so my future room will probably be larger than the one I have now so I'm thinking about getting something with punch. Originally I was looking at their boxed subwoofers but then saw the cylinders which look sweet (plus they say its cheaper), though recommend any SVS subwoofer which you think suits my needs, box or cylinder. Oh and its gotta have a built in amp since I dont have one (though I do plan on getting a Denon 3803 receiver, does that have an amp for the subwoofer?). So it all comes down to the basic question, which SVS subwoofer would you recommend to me and why? And I'm just curious, which is more powerful, the 16-46PCi or the 25-31PC-Plus?
