E-250 Front Horn 3D CAD Files + Drawings

The E-250 Front Horn is designed to accommodate either two BG Neo8 planar drivers or four THIEL 10F/8424G02 4" fiberglass midrange drivers.  Both configurations offer full bandwidth coverage from 250Hz-20kHz.

The E-250 front horn is constructed from multiple layers of 18mm thick baltic birch plywood.  Each layer is to be CNC machined on a router table.  After each layer is machined then the assembly is a simple matter of gluing and stacking the layers.  Each layer is held down to the CNC machine bed by at least four screw holes.  These screw holes are then used for alignment dowels during glue-up.
