Gargoyle, YMMV, but I associate LF propagation/amplification with mass; there has to be some way to really "anchor" at least the LF driver. I was thinking MF for the felt and/or paper horns, although I guess you could begin with a chicken wire form and build it up, ending with something heavy, like plaster. Again, Jesse covered the plaster very well. As for surface treatments, this is yet another case where the site is rife with ideas on the subject. My limited experience with horns is that everything "makes a difference", to the point where you could go nuts. I suggest getting the basic materials and shapes down first, then messing with surface treatments after that. There's already plenty of info here on drivers, which also vary considerably piece-to-piece as well as according to how they are "developed". My own thoughts have been to not ask much from the horns, but to try to use fast rates and some paper drivers. Still, I can't deny that the Cogent lower MF was among the best I ever heard, at least for one octave, ~ 4-800 Hz, and the Avantgarde Duo Mezzo seemed good enough at THE Show to make me wonder why people insist on fighting with all this. I would also favor "exponential" horns down to 200 Hz; but at LF you enter the World of Mystery, where you will need a Spirit Guide. Lastly, I would love it if there were some way to re-use all the "mules" and "stacks" I have built for testing. In fact, I'd settle for perfect recollection of the experiments and the results I got at the time!


Best regards,
