Post Subject: On PrototypesPosted by Dresden on: 11/20/2008

The first two prototypes is actually one build, the only difference being the volume/area of the chamber. (Perhaps I could have chosen more proper words in describing this part of the horn. By 'volume/area chamber', I'm specifically referring to the area/portion of the horn extending from the output [front] of the phase plug, through to the space behind the driver.)

The throat size, as well as the rest of the horn, will be the same one in both proposals. (The drivers will be of the same diameter in both designs, thus there is no need to modify the throat size, nor the rest of the horn.)

If the results obtained in both of the proposals fail to provide satisfactory results, then I would proceed to construct the third design. (The third design, however, is a departure from the base design of the first two proposals, so much that it would in essence be an entirely different horn. For that reason, I would build the third design only if the first two present marginal performance.)

I notice you keep mentioning the term, 'compound horn'. The horn design I propose is not a compound horn (a horn inside a larger horn). The design approach I'm decided upon involves using the front and rear acoustic energy of a driver toward horn loading.
