This is a little amp/stereo box I build from an inexpensive 2×25 W amplifier board. Ran RCA through the back panel, and mounted an external power jack and toggle switch. The amp powers four small full-range speakers. The smaller two center speakers have high-pass filters on them to limit their frequency to the higher range. Also, impossible to see from these photos, I drilled in a VERY tiny hole in the front which has a white LED bulb fixed behind it so show when the unit is powered on. Also looks really cool at night.
The inner body was constructed using 1/4” MDF. Then I added a wrap of poplar, which I dyed using Black Gel stain. Then I mounted the striking piece of curly/figured maple on the front using compression fittings so that I can take the speakers out in the future if needed.
It really sounds great for a small room/desk speaker set. I plug the RCA cable into my iPhone and listen to my mix of tunes. With a little more effort, this can be configured with a wireless Bluetooth receiver and battery pack to make it truly portable. I bought all the parts to do this, but decided to stay as simple as possible on my first prototype.
I am looking forward to my next speaker build. Thanks for looking and I hope it inspires.
