I still have the 12" subwoofer cabinet I built in high school almost 30 years ago. It's gone through 3 amps and a couple drivers over the years, but it's still my main subwoofer in my current home theater system. I wish I'd taken pictures of its evolution from particle board with discrete amp to nicely veneered with rounded edges and integrated amp. I don't ever think of documenting stuff like that…
