I'm just curious to know some good "do it yourself sub" projects for a beginner (me) I currently have a Hsu Vtf-2 and I love it but I'm almost finished constructing my Home Theater and am looking for more projects to do. I don't care if it is a kit but would love a tube if possible to fit behind a curtain that runs along the front of the room. My room is 14' X 23." I'd really like to build a tower speaker but I don't want to get over my head. Again, I've never done anything like this but have always wanted to build one. Any advice you can give would be appreciated. Thanks!
