DIY Speaker for Dance Events

A small presentation of a DIY speaker I have built myself. I've built it to take out when I'm going to teach dance or if I'm doing a little dance show or maybe a party in a place where there's no sound system. The speaker is energy efficient and can make great sound powered on just a 12 volt battery. There are two videos the first one focus on of the speaker. The other one focus on the amplifier. The amplifiers of a particular type of Class D amplifier called T-amp or Class T amplifier or the Tripath chipset Class T stereo amplifier. 

Inspiration I had for this project
