It's certainly possible. The only real question is whether it is advisable? There is enough difference in the frequency response of the two subs that they might not play well together. (Although they might.) And, the SB4000 has a good bit more output than the SB2000 does. So, in a small room, you might not be able to use all of the output of a 4000, while keeping from overtaxing the 2000. In a larger room, you could position the 2000 much closer to you, than the 4000, to compensate for the difference in their output. But, in a 10' by 10' room, I'm not sure that the distance difference would be enough to matter.
You mentioned in a previous post that you were considering a PB2000, so it's clear that you have upgraditis.
I understand that feeling very well and I'm not knocking it. I have been there. But, one thing that I can't tell is whether you are actually lacking something in your bass, or whether you are just concerned that you might
be? Based on what you said earlier about your settings, you should still have a lot of headroom left.
If I were you, the first thing I would do is to put on something with some serious and sustained low bass, like The Hulk
, or Batman Versus Supermen
, or a number of others, and I would start to push my subs. Turn the gain on both of them up from the 12:00 position to the 1:00 position, and see what happens. Crank your master volume a little more. How do the subs sound? In a 100^2 room, you should be getting serious room gain starting at about 30Hz or higher. So, low-frequency extension shouldn't be a problem, even with the SB2000's, and neither should total output.
But, if you do that test, and are still curious, then I think your next best path would be dual SB4000's. I think that in a small room, staying with two subs of the same size and type will work better. And, as much as I like ported subs, it is hard for me to recommend dual ported subs in a room that is less than 1000^3 (probably only about 800^3 assuming a roughly 8' ceiling).
I'm not counseling you against upgrading. That would be unAVS-like.
I am just trying to help you define why you want to upgrade, and what if anything you may be missing that your SB2000's can't give you. If you do want more of something, push your current subs hard in an effort to discover what it is.
Edit: I decided to add something to my earlier post. There is a direct link to a subwoofer buyer's guide linked below. It will explain some of the differences between sealed and ported subs, and it may help you to figure out what you are looking for. Just ahead of that is a section on room gain that may also provide a little context with respect to what you can expect.
