Svs sub : should i go with sb13 ultra or pb 13

I always preferred a sealed sub when used for two channel stereo. If it is for home theater a ported will give you more of the boom which many like for that type of application (sound effects). Why don't you order both and return the one you don't like? SVS has a nice return policy.

The PB13 Ultra comes with port plugs and is designed to be used either with or without them. I would go for the PB13 ultra and try it both ways and decide which you prefer.

In addition to the previous post, the sealed version is a relatively modest 17.5 inch cube weighing 92 pounds. The ported version is a very large 22.5 x 20.5 x 27 inches and weighs in at 155 pounds. That should also be a consideration in your choice. If that is not a problem, then go for the ported version for the reason mentioned in my previous post.
