This is my first post, Im kind of a noob. Basically I wanna build two Ported 1x15 Cabs. As far as woodworking goes I am an experienced carpenter so not much to worry about there. What I am worried about is determining the Dimensions of these cabinets. I downloaded WinISD and apparently the JBL's are lacking some stats to input. Without stats, (and proper knowledge on how to use the program, Im at a standstill. Suggestions? Ideas?
