Hello, I'm new to the forum, but have been checking out all the post on DIY subs. The more I read the more confused I get. I have decided to build my own, but just what I'm not sure. I'm hoping for some opinions on what to try. The facts: I should be able to handle the construction of the sub, I'm an ok woodworker. The electrical side will be more of a problem for me. I'm intrigued by the SVS & sono-sub idea, but I'm not sure I can get used to the big round size of the thing. The room size is around 213 sq ft, with a fair amount of glass, carpeted and 8 ft ceilings. I would like to have some impressive sound for HT, but also plan on using the system for music as well. I would also like to make use of an old Carver amp that I have to power the sub, it's rated at 250/channel and can also be bridged. Total budget $300-$500. Any thougts on what would be the most bang for the buck would be appreciated. Thanks, Jim White.
