Well i'm thinking of building my own sonotube sub, and was looking around some sites. Maybe i haven't looked hard enough, but i have yet to see a sub that looks really good. So i was wondering, how hard would it be to build an enclosure that's near-identical to what SVS uses? Those look pretty damn good, but i have no idea what they use, as the pictures on their site aren't exactly high-res. What do you guys think, can it be done?
