Small size sub recommendation needed for smal HT

Either of those would probably do well. If you really want your HT to rock, you might see if you could fit an SVS cylinder sub. They're 16" diameter, and should give more impact and a lot more deep extension for movies. Don't get me wrong, the SB12+ and SuperCube I are both well regarded, but put something like a 20-39 PC+ in there and I think some movies will absolutely blow you away . Even a 20-39 PCi should give a significantly better "HT" experience.

Great room, BTW! Looks awesome . With a good sub, that room should make you never want to go to a theater again.

I'll probably have to leave that particular advice to someone else. I don't have experience with either the SC1 or the SB12+. My assumption would be that either would do a good job. Looking at your room, I'm guessing the sub is going behind the chair? If not, I'd like to know exactly where you're trying to put it. Though the SB12+ and SC1 will be pretty good, I really do think if it's possible to move things enough to get even a couple more inches, an SVS cylinder would give a far more theatrical experience. Obviously you should do what works for you, but IMO it's worth trying to move things a couple inches if possible to get a far better HT sub.

As a side note, I'm curious how long that project has taken you. I really like the style of the room and I think it'll be a great place to sit back and enjoy a movie . I'd love to have a room like that sometime. Hopefully someday it'll happen. No matter the sub you end up with, I think you'll really enjoy your setup.

Paradigm Seismic 12

SVS has a free in home trial for the SB12 including shipping. If and only when my PB-10 dies this is a model I will really look at.

Sounds good. Make sure to let us know what you think when you get it all set up and cranking

The Super cube may look better and sound good for music. But for Ht I'd probably try to fit cylinder. Pci 20-39 ultra for that much $$. Almost the same co$t?? Only 2" bigger. Much better for Ht maybe music also. Just a guess.But the Def tech will look better IMO. Small room a Ultra would give the wow factor. This guy's room rocks.

I agree, the SB12 is a great little sub, but it (nor any sub at this price and size) will have the low end output of the cylinders. The Cylinders are 16" and the SB12 is 14" that's not that much different and if if the scale of your picture is anywhere near correct it looks like you have enough space in the front right corner for either one.

I would place a SVS PC sub in the front left corner. This is an HT room and you need the umph that the PC will provide. It will take your HT to a whole new level.
