SVS PB16 Placement

Is that an app?

It's an incredible freeware program.

So it simply plugs into my computer? Do you use this, too?

Maybe I should've paid more attention to the seating, but if there's only one or two listening positions, I think you will find the ideal spot with that big baby.

Enjoy!

sorta like fishing with a depth charge

You load the program into your computer, the mic via usb connection to your computer (older style mics used the sound card but that's more work, use a usb mic).

Room EQ Wizard is a measurement program that many use to dial in their systems... it helps analyze the acoustics you experience in your room much more accurately than Audyssey does, for example.

Exactly. And graphs look like this(just one I picked from camera roll)

So this is the result of a sweep tone. (I run sweep tones from 10hz to 200hz. It only lasts about 5seconds) So in this image, you can see the area between about 48hz and 60hz is lower in output than the rest. So, providing I have the space I would move the sub around and sweep again to check my results. This could create other issues in other areas so it’s important to sweep every time you move the sub.
This is what it might look like after good placement and eq, either built in or minidsp and/or audyssey.

You can see it’s flatter. That’s what people mean when they say “flat” response. (Disclosure, both graphs are post audyssey/minidsp)

This is kinda what an REW sweep sounds like. Except measurement sweeps are shorter.

Since you have furniture in that room, it should be possible to get a PB16-Ultra in there. One extra challenge of moving that thing around is doing so without scuffing the finish. It's probably easier to do that with the Black Oak finish rather than the Gloss Black, but the gloss finish is so much sexier. Remember, it can't be just carried up by two people. You absolutely need a dolly or a shoulder strap system. It's not a sub you can pick up and lift by hand, even with another person. And you might strongly think about getting some SVS Sound Isolation Feet for them, not to isolate the vibrations or whatever, but just to make them easier to move. The stock feet are barely there, and they only elevate the sub by 1/2 inch. I talk about this in my PB-4000 review and Monolith 15" review. They use the same feet. Those feet are not good enough for the size and weight of those subs, and with the weight of the PB16-Ultra, it can be hazardous.

Very good point about stuffing the paint when moving.A dolly is key or you can roll it into place.

Great discussion here on sub location.

REW is the best of course - it will drive placement with empirical data. Avoiding nulls at the MLP is the first priority.

Corner placement excites all room modes, which is my preference for a starting point - if the AV processor can EQ the subwoofer channel (like XT32).

Sub crawl is usually an option but not with the PB16-Ultra - it's just impractical to place that sub at the MLP. So that leaves moving the sub around to available locations in the room.

While the SoundPath Subwoofer Isolation System feet are indeed much taller, they are so grippy that dragging the subwoofer with them attached can damage the feet or even tear out the threaded insert from the cabinet.

Furniture sliders under the feet work well - get smooth ones for carpeting and get padded ones for smooth floors. Then the sub can be pushed around without damaging the feet/cabinet.

+1 on the furniture sliders I actually combined Shady and Ed's advice when I bought my PB 4000's. I bought the SVS soundpath feet so I could get my fingers under the Dang beasts. Then put the feet on furniture sliders to glide it around the room. They are pretty easy to move around with sliders

After I bought the Klipsch RP 8000's I rearranged the subs as I was dialing in the sound and it was easy with the sliders to figure out where they go.

I've been lugging that beast around best I can....hasn't been too bad.

I just ordered this mic, will probably have more questions of you once I get it and get the program going. So this helps you set your different volumes for each speaker basically?

It helps analyze audio in your room. You can use it as a simple spl meter, or you can analyze the whole frequency range. And more. Lots of good info at the REW website https://www.roomeqwizard.com/

Hmm. Maybe add the speakers for 5.1 is the next logical step if you are at 3.1. Football season is a few months away.
