Project Description:
Modeled after a standard size Lawn & Garden battery

Design Goals:
A creative addition to my workplace office to be in the theme of my job as a parts store manager and as a conversation piece with my professional clients. But really it was to have something GOOD to listen to.

Enclosure Design:
Sealed box

Enclosure Assembly:
.75 inch MDF (sides and bottom) .375 inch Clear Pine
