Opened up old speakers and made a 2.1 30 watt system with my batchmates Yash Sathe, Amogh Jadhav, Amey Haram. Designed the enclosure with wooden panels for front and back and MDF for the rest. 

I could say there were two major learnings.

1) understanding how the components work, what all components are required and their relations with internal volumes.

2)actual making of the enclosure. In the first attempt one most definitely forgets to simulate the whole making process in the head. Planning prevents a lot of mess up.

Hope to make the next one sound more sweet.
