A DIY Speaker

After watching hours of @kirbymeetsaudio and other speaker builders, I decided to try to make my own. Originally, I wanted to build a pair of towers but decided to make a smaller unit due to room constraints. My design was simple. The idea was a blend of vintage and modern in my DIY Bluetooth speaker.

I got my speaker components from Parts Express. 1/2″ MDF was used for the sides and Purpleheart wood for the face.

• Dayton Audio RS100-4 4″ Reference Full-Range Driver 4 Ohm
• Dayton Audio KAB-LED Red/Green/Blue LED Package for Bluetooth Amplifier Boards
• DA KAB-250v3 2x50W Class D Audio Amplifier Board with Bluetooth 4.0
• DA KAB-FC Function Cables Package for Bluetooth Amplifier Boards
• Parts Express 24 VDC 5A Switching Power Supply with 2.5 x 5.5mm Plug
• Parts Express #8 x 1/2″ Deep Thread Pan Head Screws Black 100 Pcs.

I built this Bluetooth speaker in a style I’d like to call modern vintage. Sides are made of MDF and the face and legs are made of purpleheart wood. The drivers are dayton audio rs100-4 4″ reference full range driver 4ohm powered by a dayton audio kab-250v3 amplifier board. It’s my first time dabbing in audio. It’s not perfect but I thoroughly enjoyed making it.
