After my rosewood horns I went bigger and better. The cabinet is built from baltic birch and MDF. The internal bracing is CNC from baltic birch.

The sides are four layers of kerf MDF that have been filled with glass beads used in bead blasting. The stuff is finer than sand and pours like water. Once filled I epoxied the edges closed.

I stuffed them with JBL 2235H woofer, Altec 802-8G w/tangerine phase plug on a 511B horn and a JBL 077 slot tweeter.

I veneered them with sapele pommele and painted the baffle board with textured paint.

I made some grill from perferated metal covered with JBL blue grill cloth held on by automotive edge trim. The grills are cut wider than the speakers so they bow out when installed. This follows the contour of the speakers.

You have fantastic wood working skills. So are these your main speakers? Also, how do you like them?
Cheers, Gio
