Attractive and tough charcoal carpet protects the box from nicks and dings, while gold-tipped spring terminals hold your speaker wires securely.

Internal Box Volume: The enclosure has a volume of 1.5 ft³ with a tuning frequency of 38 Hz.
Terminals: The wire terminals are spring-posts (one pair), mounted on the back of the enclosure. The spring terminals will accept pin connectors and bare wire up to 12-gauge. Inside the enclosure there are 0.205" male quick-slides (will accept 0.205" female quick slides) for both the positive and negative terminals. The wire can also be attached using the nuts holding the quick-slides in place.
Note: Speaker wire is needed to connect the terminals to the subwoofer.
