Hello,
New here, I recently unpacked some speakers I built when I was in Junior high or high school around 1980 with help from Mike Dzurko at Audio Concepts in La Crosse.  (Really I just built boxes and applied the silicone)  Then I found a DV12 on eBay a couple weeks ago and built a box to test it out with a small subwoofer plate amp and am really happy with the whole thing.  Those are all still great speakers and more importantly, those speakers are the oldest successful DIY project I still have.  So thanks Mike, for the speakers, and the DIY self confidence.
