I am moving in a different direction with my audio barn system. The seperate top section was designed for Dave Harris 400 horns but could easily be modified on the inside for the horn of your choice. I will supply the 3/4 maple and the paint. The new owners can put the final coat on after they move them to their new home. They are textured with Duratex to give them a Leather look in appearance. I applied Sherwin Williams Industrial Coating a very Dark Blue top coat. I was trying to achieve a rustic look with the texture and rough cut trim for a theme in my barn. I think I did just that!. 450.00 Firm for all, you can not build them for this not even close.
