my sonotube, aka ghetto tube, is near completion. my cirle cutting skills need help, but it's my first time messing with wood, so close enough. My sonotube from whitecap is 24.5" wide, .25" thick. Overall length with legs is 25.5". It's a mini monster having my psw450 next to it. Inside is a Titanic 12" MKII, 1 4" x 17" port, term cup, polyfil. I just need to dress it up! I have it inside to play with for now, it's nice, but I'm not feeling the bass enough . I have the PE250 amp powering it, I need to build a little box for it like Ron-P.
