I have 2 15 inch sonotubes i built from 15" pvc. double layered mdf baffles at both ends. they have 8 inch pvc ports in the ends, tuned to 51 Hz with 3 cubes each. the ports are flared (but not a HUGE flare). bondo around the port to seal. this is all designed to use in a bandpass box, which i also have built but if someone wants it for an explorer or something, it would have to be pick up only (its heavy)and huge at 41"x41"xabout 23" high. tubes are good to use by themselves though in an suv, possibly a crx depending on height of window line or class. i will get the exact dimensions later, theyre at my shop in storage. ive decided to go a different route in my car if anyone is interested in these. probably just make offers, ill tell you the pipe isnt cheap. i dont want an arm and a leg though, just something to start my new box. lemme know if interested, and ill try to get some pics this weekend or beginning of the week. they are painted an off white color to cover that pvc blue. ILL GET THE EXACT DIMENSIONS LATER TONIGHT.
