This is a transmission line design that I built as an experiment.
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.
Quarter wave transmission line
.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.
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.
