Gramma or Great Gramma

[Fowl]

Hey Guys,

I have a question, I recently ordered a PB12NSD and nor sure if I need a Great Gramma or Gramma.

Am on american musical site, but not sure which one to order. Help!

Neither will be a perfect fit.

PB12-NSD: 18" wide x 25" deep (long) 74lbs

Gramma: 15" wide x 23" long
Great Gramma: 19" wide x 30" long

Since it's a front firing sub then if you're on carpet you might want to consider 4 of these. On hardwood then IMO the Auralex would be a better choice. I'm using 4 under my 85lb Hsu ULS-15 which is on thick carpet over a concrete slab. They come in a lot of different sizes but I'm using 3"x3"x3/4" ($3ea).

Fowl, just keep in mind that your sub will overhand by 1.5" on both sides, but not front or back, you should be just fine. Just make sure your careful on placing the sub in center. I have the SVS PB12 NSD/2 and had to use two Grammas just so the sub wouldnt overhang, I could never get it placed right so the sub would always tilt slightly to one side, till I used two Grammas and now that is no longer an issue.

Enjoy the new Gramma they work great.
