Sealed Box Alignment:
Home: You can use this woofer in a sealed and stuffed box of about 1.25 cubic feet for an in home F3 of 45Hz. If used with a plate amp that has a built in boost, it might get down to the mid to upper 30's.
Car: If a 1 cubic foot sealed box is used in a vehicle, assuming 6dB of cabin gain, your F3 would be about 27Hz.
Vented Box Alignment:
Home: You can use a 2.5 cubic foot box with a 3" diameter vent by 13" long for an F3 of 30Hz. If using a plate amp with a built in boost, it should go to the lower 20's.
Car: Sealed boxes are usually recommended for autosound applications as vented boxes can seem boomy.
