Portable Bluetooth Speaker

Hello fellow speaker builders! This is not my first speaker build, it began when i was young, my first few speakers were not that great and full of neon lights. With each build the quality improved and the speakers began to look more stylish. I build this speaker when i was 19, it was a very hard and complex build but I have learned a lot. Unfortunately I have not documented the entire build. I am from Holland, so there can be some misspellings in my English.

Components i used:

- TA2020 12-15V amp

- Tangent speakers

- Battery 12V 7.2Ah

- Marmitek Boomboom 75 Bluetooth Audio receiver

- Usb Charger(to charge my iPhone)

- Crossover

- Speaker front cover(not in the pictures)

Frame and Bending Wood

The first step was creating a frame as shown on the image. Then I bended wood around the frame, 2 pieces of (i think it was) 0,5 mm that i soaked in water for a few hours, I never bended wood before so this was a very hard and annoying job.

Components and Wiring

Then I placed all the components into the speaker. I also fitted the Bluetooth receiver in the top of the frame, which was also very hard because I had to place the circuitboard with the button and still maintain the shape of the speaker which resulted in filling the gaps with filler or putty. Then I drilled all the holes in the mounting dish for all the connectors on the backside and then I wired everything.

Sanding Down and Painting

The final step was sanding the speaker so i could paint it. This was a very time consuming job, I'm a bit of a perfectionist so I wanted it to be perfect. Then I painted the whole thing, first with primer and then with white paint. I have never painted before so this was also new to me. It took me seven coats for the result that I wanted, between each coat dry and wet sanding. I'm happy with the result, I'll hope you like it to!
