Click here to see the bluetooth speaker kits available at Parts Express. They recommend an enclosure with internal volume of 0.3 cubic feet, or 518.4 cubic inches for the kit I used. My design has internal dimensions of 10"x7"x7" which is 490 cubic inches. Although it is slightly smaller, it sounds awesome! Click here to download my plan for this project. Adjust the plan if you use a different kit.
The kit came with everything I needed, except for the suggested two 1" Speaker Port Tubes (Part #260-470) which are sold separately. I also ordered a nicer Amplifier-Style Volume Knob (Part #240-2206) that looks really classy.
An Audio-In jack is included in the kit. I mounted this on the right side of the speaker so it is easily accessible. This jack allows you the option to connect an external device using a 3.5mm audio cable, such as a CD player.
I mounted the power adapter jack on the back so it is out of the way and not visible. The power adapter is also included in the kit.
I bought a set of four rubber feet from Ace Hardware. They come with really short screws, so I chose to use longer 1.25" screws that will secure the feet and the bottom to the enclosure. Make sure you drill pilot holes in the sides to avoid splitting the wood.
I used the cutting templates in my plan to cut the mating finger joints on the corners with a scroll saw. This worked out great. Just make sure to cut out the correct pieces so all sides mate up correctly. Also check for square when gluing it together. This was a fun project to make and perfect for Scroll Saw users. I hope it inspires you to make one too. Rock on!
Wiring Tip! The picture below shows where to attach the red and black wires to the power jack for the kit I used. Connect the red wire to the terminal on the end of the center post. Connect the black wire to the middle terminal. The other terminal is not used for this kit. Use electrical tape or shrink tube to isolate each connection from touching each other.
