Here is a photo of the new folded bass horn with a four foot by four foot plywood panel set over the top to enclose the final flares at both sides of the horn. The corner midrange horn is set over the top with the Magnavox horn tweeter. In the foreground, you can see a pair of 68uF nonpolar capacitors and a large induction coil temporarily wired as a series crossover so I can listen to music through this and do more testing. This is a "bare-bones" setup. The whole thing could be made more attractive by constructing a large curved shelf or bench in place of the plywood panel. The bass driver will eventually be inside a back chamber and not visible.
