Corner Midrange Horn Adhesive Drying

Today, the corner midrange horn center flare assembly is further fitted and provided with a wood plug to close the opening adjacent to the mouth ends of the two small horns constructed yesterday.
Here is a view of the center flare assembly with the wood plug positioned over a gap.

I applied flexible adhesive caulk to the joints in the horn flares.  The adhesive will dry overnight.

I conducted a test of the frequency response by holding a small square baffle with attached small two-inch driver taken from a Cambridge Soundworks computer sound system over one of the throats.  Driven by a sine wave generator, at least to my ear, the horn appears to have useful output from about 300Hz to about 3000Hz.
