DESCRIPTION:
Designing a folded horn sub woofer in Google Sketch-up, and then making it come to life! Trying the best I could to keep costs down, the parts were cheap or free (the 10" sub) and only cost around $20. If there is enough interest, I can post a video of it going so you can hear it. I would just have to find music YouTube won't complain about.
