Has anyone ever made any speaker cabs that are completely ridiculous? Like a 4x18? Or an 8x15? Etc. I'm really wanting to build an 8x15 if I ever get the money and power plant to go along with it. I don't care how it would sound...it's 8 15s! That would be so cool...but also about 100" tall and 50" wide. Now I need me a roadie with a REAL strong back!
