Have been reading thread after thread here.

Room size = 19x19x9=3249 cubic feet but opens direct onto another room that is 26x18x9=4212
Location = basement, concrete slab with glued down engineered hardwood
Use = 100% movies
Budget = $1,500 max including shipping

I was pretty much ready to pull the trigger on an HSU VTF-15H but WAF has entered the picture so it has me now considering 2x SVS SB12-NSD's since those could be placed on either side of our couch under end tables so not as obvious.

Would appreciate input.

Thanks in advance.

That is too much space for 2 SB12's to fill and pushing it for one VTF15.

What is a good rule of thumb for adding a second HSU VTF-15H based on room cubic footage?

I have 2 SB12's that I am about ready to try in a very similar space as you. Basement, solid flooring and about the the same cubic feet. Also the room will opens up to the stairs leading to the main level. The main difference is that we have ceiling tile and the ceiling is 8' instead of 9'.

I choose the SB12 so I could install one in the display wall, and it fits perfectly between the studs. The second is going behind the seating position, in a corner.

If I can get them plugged in in the next couple of days I will report back. That said, my basement isn't finished yet. We are waiting on flooring and some other things, but I think it would us at least an Idea of the final output.

+1. Especially in a basement (concrete-floored) space.

OP, if you can't do dual VTF-15Hs, I think you should at least shoot for something like dual SVS PB12-NSDs. IMO, and YMMV. smile.gif

-- Edit --
Just noticed that you're considering nearfield placement. From my understanding, that's a good approach in a large space. In that case, dual SB12-NSDs could work.

I think the limit used to be 6000 but don't quote me I know for a fact it works great in 4500 because that is what I have.

I would try to get as much performance as you can in a single package, since shipping seems like its going to be pricey no matter what. I would look at something like the Seaton Submersive, which ought to have no problem pressurizing that space, and is not too much bigger than a VTF15h. But a couple of SB12s might work for you too, as long as your expectations aren't too high.

Your max budget is only a few hundred $ away from dual drive VTF-15Hs. My advice: buy 1 VTF-15H now, save a little bit more money until you can get another.

Dual VTF15Hs are ~ $2100 shipped which is $600 more than what he is trying to spend. But I agree with you to go big with a single sub now.

Actually, Dual VTF15Hs purchased at the same time is $1,987 shipped. If purchased separately, it adds up to $2,036. The latter would increase OP's budget by 1/3 but I feel if he is willing to wait and invest that much more into a 2nd VTF15H somewhere down the road, it'll be very much worth it for the space he is trying to fill.

I am going to make a thread about mu recent subwoofer purchases and my almost finished, layman, home theater. But in a nutshell, I have a PB12 NSD that I used to use in a small room, about 2500 ft^2, then a different room with about 3500 ft^2 and the PB gave me tons of oompfh.
I was quiet amazing, but since I put it in my basement that is around 4500 ft^2 and open to the 1st floor and many other smaller rooms, the PB12 just couldn't cut it anymore.

I just got the 15h package (2 HSUs) and holy fvcking sh!t.... The bass is so overwhelming tremendous, I can't stop smiling when they rip. I haven't even put them to reference lvl on the Receiver yet and my house literally shakes. My 1st floor is shaking like nothing else.

One thing I must warn you though, they are monstrous. The box is giant, the subwoofer weighs a friggin ton and the Driver looks menacing, but it's a gorgeous woofer imo.


I hinestly believe that one 15h would be good enough for your room and second one down the road would be incredible.


If you decide to go with the PB12, which is an incredible sub and nearly unbeatable, as long as you don't put it in a huge room, I have mine for sale. 4 months old. pm me if you are interested and live in the tri-state area.


good luck hunting,

Guys I don't think the OP is located in the continental US, that is why his quotes are fairly high. Two VTF15hs might cost him $3k. At that point, it probably isn't much more to get a single Submersive or Captivator, even including shipping.

Thanks for the input thus far.

I live in Canada so by the time I add shipping, duties, exchange, etc to the price of the HSU I'm into the $1300-$1400 range which is okay. I was ready to pull the trigger on this but the size of the sub became an issue.

Clearly WAF is an issue so 2 HSU subs isn't going to happen (at least not right now).

The 2 SVS subs are small enough that they can more easily "disappear" in the room and total cost is $1400 shipped so virtually no difference on cost.

The decision is performance versus WAF. The VTF15h will have more output, but the SB12s will fit in better and still ought to sound good. You have to decide what is more important to you.

You think 1 SVS PB13-Ultra would be enough in a 3000 cubic foot room?? or should I go with 2?? biggrin.gif

I have heard one in a 5000cf room do a nice job so 3000 should work fine.

I've heard a PB12NSD in a 3000 cubic ft room and it pounded pretty well, so the PB13 would pretty much be excellent.

OP, I did get my two SB-12's hooked up and listened to them in my space last night. Overall, I thought it was pretty good. No, it wasn't OMG crazy bass, but when listening to industrial rock (Celldweller) or Eric Clapton, the bass filled the room and sounded wonderful and clean. Sorry to say this, as I know movies was your main concern, but have not tried movies as I don't have the TV mounted yet. I will say in my testing in another location that had more area, a single SB-12 produced some nice bass with movies.

I played around with one sub vs. two, and which sounded better, the corner loaded unit in the back or the front unit. Beyond the extra output, the second sub evened out the response in the room. Alone, the corner unit produced a little more output, but was somewhat directional. During music I could tell it was coming from behind me instead of the front. All of this is to be expected of course, but I thought I'd share anyway.

I know you would get more bass out of a larger, ported unit, but for the size and cost, I was impressed. Beyond that, my wife is happy.

Good Luck!
