This is a DIY sound system that fits compactly in the Solder and Circuits lab. There isn't enough room for a big infinite-baffle speaker enclosure, so I built a chair around the enclosure.
The amplifier for the Speaker Chair is homemade, also. The system has good bass and overall good sound. The only parts that were purchased were the speakers and some connectors, otherwise all the parts were in stock in Solder and Circuits. This project is along the lines of the Maker Movement.
