After months of deliberating about my under-bed subwoofer I have decided to build it out of the components I already possess. 60w + 60w amplifier + 2 x 165mm drivers. The cabinet dimensions are 600(W) x 200(H) x 200(D).
It makes sense to power each driver separately. So here's the question . . .
If I use a full size panel as a brace I will effectively have 2: 300x200x200 cabinets. It is easy to calculate port size and tuning frequencies. However, without the brace I will have two drivers using the same airspace and sharing a single port. Will this configuration produce better results?

Separate airspaces are required when the woofers get different drive signals. If the signals are identical, then it does not matter if the airspace is shared.
If you've got your drivers' TSP's, simply throw them into an analyzer such as WinSIM and see what happens.

With two subs, I think I like the sound of mixed bass better than stereo feed, at least with my two rather heterogeneous subs (heterogeneous is good and needless uniformity is bad).
