Bookshelf Speaker Box 4 Inch Driver

I Designed these speaker boxes for 4 inch Dayton Audio Coaxial speakers with 5000 hz crossover for the tweeter and the correct air space. I glued, sanded and painted them for a more pro look! They sound great and will probably work well with other 4 inch drivers! Software, settings and parts list below.
