Finally, after making Bluetooth boom box speakers for each of my older two daughters, I found time to make a pair of stereo speakers for my shop.

All the wood was remnants that I had laying around in the shop:
Sides are Red Oak plywood
Top & Bottom solid Red Oak
Front 4/4 White Oak
Back is plywood with laminate

The front is finished with Dark Walnut gel stain and the sides and top/bottom with Cherry colored Danish Oil, followed by satin wiping varnish.

Speaker design was a morph of some different plans I found online, resized to optimize for the woofers. I used 6-1/2 Dayton audio woofers and 1” soft dome tweeters, both from Parts Express. These are driven through a 4 KHz crossover from Amazon. Not audiophile level kit… but decent bang for the buck.

Speakers are insulated with egg crate polyurethane packaging grade foam and the crossovers are mounted on little aluminum standoffs that I salvaged and modified.

All totaled, I have about $90 into the build.

I really like the way the Danish oil brought out the grain fleck in the Oak plywood. and I like how the two tone with the darkened reveal turned out.

Speaker builds are fun, but I think I’m done for a while.

Thanks for looking.

Matt, I followed your build on these and have to say they finished out remarkable. Only thing is I wish I could hear them as well. I bet they sound nice! Well done buddy!

Did a test drive tonight and they sound pretty good. I’m surprised that the little 6” woofers can produce such deep base.

I’m using an anemic little Bluetooth amp that I picked up on the cheep to drive them and it doesn’t have enough power to make them crank. I’ll have to check into other options. I think I have an old car stereo amp kicking around, maybe I can scrounge up a 12 Vdc power supply and feed it with the BT amp…. kind of like a pre-amp.

Very nice, and that quarter sawn oak on the side panel does look great.
I agree, a 6” can produce a lot of sound. In my college dorm room, I had a pair of JBL bookshelf speakers with a 1” titanium dome tweeter and a 6” woofer, powered by a Harmon Kardon 60 watt receiver. People couldn’t believe the great sound.
Enjoy the music in the shop!

- oldnovice

The speakers are wired to the little amp, which has BT connectivity as one of several input options.

I use an old cell phone like an iPod and BT link it to the amp. That way I can use the phone like a remote and keep it in my shop apron.

Great job, Matt! I really like the black reveal line. Hope you enjoy them for years to come.
