Project Highlights

(1) Customer had originally produced this part by cutting, shaping and welding sheet metal to a tubular frame.

(2) Pentz developed special tooling capable of utilizing precision dry sand molding techniques to make the speaker as a two piece cast assembly. This eliminated the cost and headaches of the original assembly process.

(3) The result was a speaker housing with a smooth, seamless contoured surface and superior acoustic performance.
