About the SPL Boxes SB115V

Bob Bihlmayer

We all know how a good subwoofer can enhance your musical enjoyment, but not everyone wants to build their own box. SPL Boxes to the rescue! These heavy-duty enclosures can take the punishment of the car environment, with rugged 3/4" MDF construction to give your sub plenty of support. Attractive and tough charcoal carpet protects the box from nicks and dings, while gold-tipped spring terminals hold your speaker wires securely. This SB115V box holds one 15" sub in a ported enclosure.

Product Research


Design: The SB115V is an unloaded, ported enclosure for a single 15" subwoofer. It is constructed of ¾" MDF (medium-density fiberboard) and covered in charcoal colored carpet.

Internal Box Volume: The enclosure has a volume of 2.7 ft³ with a tuning frequency of 32 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.

Brackets: Brackets for securing the enclosure in your vehicle are recommended.
