Project Description:
This is a transmission line design that I built as an experiment.

Design Goals:
I wanted a low cost Bluetooth speaker for at work in a garage setting. I went with a transmission line design to get the most out of the speakers.

Enclosure Design:
Quarter wave transmission line

Enclosure Assembly:
.5″ birch ply for the exterior with .25″ oak for the interior and assembled with wood glue

Tips & Tricks:
It’s awesome that Partsexpress.com provides the T/S parameters for these drivers. That information made designing this enclosure much easier.

Conclusion:
I’m very pleased with this project overall and I am definitely satisfied with the speaker kit. It sounds great and it was fun to build.

About the Designer:
I do a lot of different carpentry and woodworking including building custom subwoofer enclosures for car audio applications. I got into these Bluetooth speaker kits as a way to learn a little more about audio and the way enclosures affect sound.
