Project Category:
Portable Speakers

Project Level:
Beginner

Project Time:
8-20 Hours

Project Cost:
$100 – $500

Project Description:
A 36″ portable Bluestooth speaker.

Design Goals:
To get a device that looks good enough and sounds good enough for it to be your one device. Home audio, patio or pool, or tailgate.

Driver Selection:
295-424

Enclosure Design:
This first attempt is in pine to keep cost down until I figure out how to construct it. I used a maze vent to get a bit more low end which worked out well. It was a totally guess on my part. The design software made my head hurt. Sounds Great!

Enclosure Assembly:
Brads and glue

Crossover Design:
High pass filter plate to the tweeters (cost saver) and I passed through direct to the woofers.

Tips & Tricks:
My only tip is to make sure you have enough room for all the electronics!

Conclusion:
The sound is great, the battery life is great, the bluetooth signal need work on the next one, the looks turned out well. I will however do much better on the next one.

    Is there a schematic so that I can reproduce this speaker? I purchased the parts required but now need to work through the build.

      Sorry DLaC. I more or less wing’d it. I could not even tell you the measurements other than is 36″ long. I’m sure I could be improved upon with some more audio science. It’s big. Maybe too big to be a grab and go boombox. But, for my home and only moving it around a little bit it works great for me. Big sound once the speaker were broken in.
