Project Information

I made this Bluetooth Speaker out of walnut and maple using a speaker kit. I cut the box joints with the scroll saw and glued the four sides together. The top is glued on, but the bottom is screwed onto the enclosure by using longer screws through the rubber feet. The only tricky part was drilling the holes for the switches, jacks and knobs. They were not long enough to stick through 1/2" lumber, so I had to use Forstner bits to drill counter-bore holes on the back of the panels so the parts would recess far enough for the shafts to stick out.

The speaker kit cost $59 at PartsExpress.com. They have different kits available and some have rechargeable battery packs to make it portable. The kit comes with everything you need, except they recommend adding the two port hole tubes. I added on those and also bought a different fancier knob than the one that comes with the kit. Most of the wiring in the kit just plugs together, but you will have to solder wires to the power jack and speaker terminals. (Parts Express liked my project, so they are offering my viewers $5 off $50+ orders until 12/31/18 with code CWFIVE.

For the kit I used, they recommend an enclosure that is 0.3 cubic feet, or 518.4 cubic inches. The internal volume of my speaker is 490 cubic inches, so it's a little smaller. Speaker enclosure design is a really deep rabbit hole you can go down if you are an audiophile and want to get real technical. There is even software available for designing optimum enclosures for each brand/model of speaker out there. I didn't get too technical with mine. The speaker sounds great and I really like the appearance of it.

Very nice job on making such a nice retro style case for the speakers. I like it.

Nice speaker! Great job! I build lots of speakers, from little ones like this all the way up to 18 inch bass bins and I assure you, you would have to have at least a 10,000$ test instrument to tell the difference between 490 cu. in. and 518 cu. in. cabinet volume! As long as it sounds good to you, that is all that matters! By the way, did you use the rechargeable battery pack? If so, how is the "play time" on it?

Thanks everyone! I did not get the battery pack, but I may add that later. I think they sell it separately.

Very nice Steve. I'm planning on building one of these for my daughter for Christmas since her iPad is her entertainment center. Hopefully this should help out with the sound quality. I just wish there was a way to really hear what it sounds like…. Thanks for the discount code!
