Back loaded horn plans

Ha, almost 6 years later one would think that the heater core is done. Actually got that and many other repairs since then. Life had been so busy, I forgot about this project, until I was cleaning up my audio room and stumbled upon these drivers. Was doing a search on this box design when I stumbled upon my old thread. I am going to see if I can source some 1/2" Baltic birch and make some saw dust this next week.

Wish me luck!
