If you build the cabinet between 4.0ft³ and 5.0ft³, tune the cabinet to 38Hz. If 5.0ft³ to 6.0ft³, tuned to 35Hz. If 6.0ft³ to 7.0ft³, tune to 33Hz. If 7.0ft³ to 8.0ft³, tune to 30Hz. Do not go larger than 8.0ft³.

To tune the box, size the port accoring to the Helmholtz formula below. Make port area at least 20in².
