I'm designing a center console speaker box to house a 10" and two 5.25, along with cup holders and a junk tray. The sub portion of the design is done, but I had a question about the chamber for the 5.25s. Right now, I have it designed with the chamber shared between the pair. Will the speakers interact because of the common airspace to the point I would be better off with a divider for two chambers? The speakers are Polk Audio DB521

The jury is out on that. Myself I wouldn't bother with a divider but you might get opposing views. The drivers are interacting equally with one another so...
Is the chamber vented? This can be sim'd in WinISD assuming the signals to both left and right channels is identical for bass. A BR designed for one driver if you add a second will have poor performance worse than single.
Depends on if you're running this as mono or stereo, and how much/if you care about the sound coming out of this thing.
If my inferences are correct, this is to go in a car.
There's a lot of noise in there anyway, so I wouldn't bother with the divider (unless the cabinet needs bracing) - a bit of stuffing will reduce any crosstalk* to (probably) below the noise floor.
*if run stereo. If its mono, there's no problem.

I agree, no divider necessary, but I am curious as to just what type of vehicle, besides a truck tractor, has enough room for a divider that size?
