One or two subs?

96CivicEX06 is actually correct on this one. Every massed object has a resonance frequency. The more mass the object has, the lower the tuning frequency. It gets to the point where the frequency is low that it hardly affects the system, at least audibly. Assuming the MDF is not porous, and there is no resonant frequency, the transmission sound loss would be infinite, which we know can't happen as long as the MDF can resonate

But you're statement of the difference it makes in the real world isn't too large at stake. Most of the competitors I know will build a box large enough for their subwoofer and then sound dampen the box. After all, the box will be in a car's environment where such little things will be inaudible when built well.
