Got my new SVS PB13-Ultra. Wife was like --> :eek::eek::eek:

Currently the sub is where my other sub was located (to the left of the left-main speaker). The sub is too large to stay in this location. I have one other location to place my sub. However, I could use some advice on which way to point it in relation to my sitting area and my left-surround speaker.

Below you will see a room layout with four different options. The drawings are to scale. All the speakers are in red. I've added a half-circle to the sub to indicate the front of the sub.

Any suggestions on which option would be optimal in my room will be much appreciated.

Thanks!

I don't mean to sound like a jerk, but your sub is in pretty much one spot in all four options and only needs to be swiveled around. You spend a lot of time drawing all that to scale. Why not just listen with the sub pointed in various directions and decide what sounds good? That's the best way to tell.

Just GUESSING...you have a very open floor plan with no obvious places for a sub:

Option 1 -- you'll be pushing air toward the open kitchen doorway.

Options 3&4 -- the bass might be directional.

I would consider getting a smaller sub that will fit between the fireplace and the (entertainment unit?).
Not sure if its its drawing but, it "looks" like the sub would fit in that spot.

I can't imagine that where your current options are your going to any kind of integration.

Like NCDave said, your either pushing all that energy out of the main area or its going to be very directional.

test,

I'll suggest you experiment with the sub placed in the space between the fireplace and the left hand side of your front stage. I imagine the sub will fit in there if turned sideways preferably with its front facing towards the fireplace. Your left (and may be right) front speakers may need to be shifted forward a tad as a result.

Hope that helps a bit.

Bass is omni-directional. Bass "disperses" in a 360 degree pattern. You won't be pushing air in one direction or another by facing it different directions. The only difference you'll hear by facing it different directions is that it will interact with the room slightly differently. The modes will change somewhat. If you have any kind of measurement capability, you can measure and use the option that provides the least excitement of modes.

Also, a side placement will integrate just fine if you cross it over at 80 Hz or lower. Bass below 80 Hz is non-directional, (you can't tell where it's coming from.) However, if you crossover above 80 Hz, you'll start to hear bass sounds coming from the side. In that case a front placement is much better.

Can you place it in the front right corner and shift your system over towards the fireplace? This will give you corner loading of the sub, which will gain you some output, (up to 6 dB), but it may also excite more room modes. Nonetheless, if it can work, it's worth a try.

Good luck.

I ended up going with option 3. I'm unable to keep the sub in the front (WAF) since it sticks out further than the entertainment center. I moved it to option 3 and even without calibrating it again it sounds great. I still haven't had a chance to re-run Audyssey and test with my SPL meter (too much homework this weekend). :(

Sometime this week I'll get a chance to recalibrate everything since the sub moved and the left-surround was also moved.

Overall I'm really impressed with the sub and talk about DEEP bass! :D

The size and deep tones of this sub have been driving my wife nuts. She likes it, but still is having trouble getting over the size and power of this sub. She told me she dreamed last night that the sub was so loud it was opening and closing our kitchen cabinets. She came home and I was in the kitchen tearing all the cabinets apart because I was replacing the facia with some sort of special latch. She said saw dust was all over the place, the cabinets were all torn apart, and I was all happy because I figured out what that clanking noise was when we watched TV.

Dang, I never realized my sub could freak her out so much she is having dreams about it tearing up the house! :eek: lol

Probably also depends on the slope of the crossover and your hearing ability. The ultra 13 built in crossover has a slope is 12dbs per octave which at 80hz could cause localization problems.

That's funny, Dust. I could definitely see my woman having the same type of dreams.
So is your ultra making the kitchen cabinets rattle/slightly open and shut when the bass hits?
That's some strong bass.

.....it don't count till you either break dishes or crack plaster.

You need a wall on the south end of the diagram then place sub in far corner aimed out....

Another example of a fireplace ruining a room for HT really...heh...

It really doesn't rattle the kitchen cabinets. Although, I imagine it could if I turned it up enough. Even though it is not in a corner, there is still plenty of bass for my room. I only have the gain turned up to about 10 o"clock and you can actually feel the bass during explosions and when I have the AVR up to 0 to about -6. I think it might break my house if I had it in a corner. :eek:

I told my wife I was going to turn the fireplace into a custom sub enclosure. Since we live in Phoenix, AZ and never use the fireplace, I thought that was a great solution. For some reason she really didn't see the humor in my suggestion. :rolleyes:

Hey Dust,

You should post some pictures of your sub in it's new location.
Is it functioning as an endtable?
