Choices are dual SB12-NSD, single PB-2000 or SB-Ultra 13. I don't really want to go over budget of 1,000 usd and all 3 options are in budget. I like the idea of duals and really want to go that route, but I'm leaning towards the Ultra 13 but don't know if or when I could add a 2nd one. Any input would be great.
There is actually something to be said for all three options. Each option has some potential advantages. The PB2000's main claim to fame here would be more SPL than an SB13 at 20Hz. Dual SB12-NSD's would give up just a little SPL to an SB13, but not a lot. And, you would have two of them for enhanced frequency response and bass envelopment.
You can do some comparisons of output at different frequencies by using this Data-Bass table. The PB2000 will have about .6db more output than the PB12-NSD which is listed on the table. http://www.data-bass.com/systems
For me, the decision would probably come down to how likely, I thought it would be that I could add another SB13 somewhere down the road. If I thought I could, I would probably go for the more powerful SB13 now, and add another one later. If I honestly didn't think that there would be a future opportunity to add another Ultra, then I might buy two SB12-NSD's now.
This is one of those times that the 45-day trial period could work in your favor, if you wanted to try an SB13 in order to decide if having only the single sub would suit you. If you think that there is any chance that you can add a second similar sub later, I would nearly always counsel buying the more powerful sub now. Generally, our bass tastes tend to increase over time, rather than to decrease.
Edit: I just double-checked prices, and it appears that you could get three SB12-NSD's from Amazon ($400) for the price of one SB13 from the SVS Outlet ($1200). If you can afford the SB13, three SB12-NSD's might be tough to pass up. Choices, choices.
