    He only built the enclosure ... I was expecting a 50Mb AVI of the guy winding the coil and magnetising the magnets.

    There is a strong and thriving community of DIY audio enthusiasts. I myself built my own tube preamp, interconnects, and power amp. Try http://www.speakerbuilding.com/ for information about building speakers. For broader information, go to http://www.stereophile.com and click on "Links 2 Die 4" (the l337-ness is theirs, not mine) and then on the DIY link.

    One 26 inch home-brew subwoofer, coming right up! [mit.edu]. They built it with the driver from an ancient hard drive. For those not up on Norse mythology, moljnir (several spellings seen) was the unstoppable hammer of the gods, carried by Thor himself. I'd say a building-shaking sub comes pretty close to that description. ;-)

    I'm no acoustic engineer, but it seems you'd have to do some calculations to make sure the resonant cavity matches up to the speaker. I don't see any evidence that he's done any calculations whatsoever. How would you go about determining the optimal size and shape of the cabinet? Or does it not matter on such low freqs?

    In the 20 or so years that i've been listening to them, subs which use relatively small, high-excursion drivers in a sealed enclosure have been the best, especially for percussion. They need more power, but it's worth it.

    Ported subs just don't seem to have the *punch*, and it's tiring to listen to music which has a lot of info near the resonant freq of the port.

    You're much better off scrapping the whole cone idea and go for a vane/cylinder design. They're much easier to build and often give much better results in a homebrew situation. Try here for some explaination: http://www.mindspring.com/~sdinc/pages/td_new_fam. html
