Post Subject: Horn Loading of Both Front and Rear Acoustic EnergyPosted by Dresden on: 11/10/2008

I've been doing a lot of research on how a properly designed horn works (from initial Western Electric designs to present day efforts) in order to get a real grasp of what will and will not work. I've read and saved hundreds of papers and designs from the internet to date. Interestingly, the more information I collected, the more it appeared that older, 'vintage' ('30s to '40s) designs were created with a true understanding of acoustic energy and proper loading. (I'm more a designer and a 'hack' than anything else, but the theories point me in that direction.)

I've thus far deduced that in light of the fact that the driver's excursion will be lessened and distortion will accordingly remain negligible (as a result of the horn loading), a model with horn loading on both radiating sides of a diaphragm may work.

I'm glad you replied since it confirms my previous conclusion--only in creating two models (one with front loading and sealed back, the other with horn loading using the acoustic energy from both sides), and testing said models, can I obtain real-world figures, both measured and heard. (I concede that horn modeling--without actual construction--can only take anyone so far. In reference to Hornresp, I believe it was created for the sole purpose of driving people insane [never mind even calling it a usable 'program'].)

Learning how to use SolidWorks to model my Mid horn will be challenging (if I can master the program at all). But if I can accomplish that, I will also be able to model the two prototypes for the Mid/LF horns.

Thank you again your for valuable feedback.
