I don't have any in my lineup, but direct radiating subs are pretty easy to design. No internal standing waves in the passband, because the boxes are much smaller than a wavelength. So you can expect them to act just like T/S simulators say.
Basically what I'm implying and suggesting is to find a good quality subwoofer driver that models well in a one cubic foot box. I'm guessing it will probably be an 8" or 10" woofer. There are plenty of this type in the carsound realm.
