This is my finest rotary subwoofer yet. It has sleek 2mm carbon fiber blades and it is set up in the trunk of the car coupled with a 15 inch box subwoofer. the fan and the port are sealed to the interior of the car creating a dual coupled system with port and infinite baffle. If this doesn't have good response, I don't know what will.
