Thanks for the reply. I have always been aware of sound, whether musical, mechanical or natural. Because of this there was a realization that material used in the build musical instruments played a big role. I am not as musically inclined as my father was, but have some sort of innate ability to build, and found it possible starting in Jr. High woodshop. The connection became obvious when I built my first set of speaker in my senior year. Corner horns, that being the K-horn designed by Paul Klipsch became available for plans to build a set. The plans were offered by Speaker Lab back in the day, and I was off to the races. Although I didn't care for the midrange horn, the tweeter was very good and the bass unforgettable. At 63 I have had several projects to build since my high school years, and try to choose woods/materials that will accomplish at least part of the signature of the build.
Here is the project that I am attempting to mate this servo sub project with. It is a back loaded horn designed by Steve Dekart of Decware Audio. Although it does very well for most of it's intent, I chose a different driver made by Mark Audio that, because of it's size will only be able to produce bass to certain level. The sub may well be the answer.
Here is a shot of the speaker project:
