Here's a Jpg exported from Google sketchup of the ultimate compound horn I'm going to build for the Fostex FE206E. It will have bass response flat down to between 35 and 40hz(if you go lower you sacrifice the ability to play loudly) and matching response all the way up to 20Khz. It will be finished in maple and wallnut veneers and stand about 6 feet high(1.8 M). It should be capable of 120db down to 40hz!

maybe ultimate in sound reproduction but the price for the design? ;-)Here's a Jpg exported from Google sketchup of the ultimate compound horn I'm going to build for the Fostex FE206E.

check: Sonido - AION for inspiration.
Or maybe a BiB for an easy build?
Have you run simulations with this design? I would be interesting to post them for everyone to see if you have. Make sure not to skimp on the bracing. Maybe consider enlarging the mouth or lowering the driver so that they can be firmly attached to each other? You certainly don't want the driver/throat area flexing. And you really can't go wrong with more bracing in the mouth of the horn. I learned that one the hard way (my avatar).

An interesting design to be sure, or so it appears from the render.
If you'll forgive my being picky though, perhaps not the happiest choice of thread titles? It's what you regard as your ultimate compound horn for the (defunct) FE206E, not 'the' ultimate. There's a difference.

So what is "the" ultimate then?
There's no such thing. Just different sets of compromises. You pick those that best suit your particular requirements and accept the fact that one universal perfection doesn't exist, in compound horns or anything else in this life. More's the pity, althogh it would probably make life less fun.

Of course....
The gray trace is the open baffle response for comparison, as hornresp can't acurately simulate high frequency response.

Just do what I've starting doing, when you feel the need to write a critical comment. Write it, read it over, mull it over in your head, feel good about expressing yourself, realize no one cares, think about how they are going to react, realize your just being an old crab, then delete it before you post it! Of course it's "my" ultimate, that's why "I" posted it!!!
very nice design(I posted on the wrong thread earlier but deleted) would love to see a version of this in lacquer white, I imagine a car body shop could spray it up relatively cheaply. Also the curves could be made very easily by laminating 'bendy' mdf (the scored type made for curving).

Thank you for the complement. Yes the curved parts would use bending plywood, and then veneer can be applied over it, or it could be painted like you said.
