Hello Here's a place, http://colomar.com/Shavano/stereocab.html . I built this cab for my nephew, but I made it mono with switches in back for 4 and 16 ohm impedence. And also a switch for the piezo's on or off. The speakers are delta pro 10's, real cheap at parts express. Really nice speakers. My nephew loves it. He uses a mesa boogie head. Thas all.
