I don't like the solid bracing, had been known to decrease LF performance.
A few holes in chosen places should fix it though.

You should take the dimensions and input it into hornresp.
Or AkAbak of your up for it.
Way less expensive than building it to find out.

I doubt that this is a problem. The solid bracing doenst do anything to the sound, except doubling the frequency of the standing waves in the horn, which is a good thing. If you have proof for your assertion, i would love to see it.

It was mentioned in a post about the furybox due to actual testing. And I think Tom Danley also mentioned it in one of his posts.
You can also see that the DTS-20 has a gap in the bracing.

Well, thats hard to check out for me... but after all, it shouldnt make much of a difference if you use solid bracing or not, except that its cheaper to use less bracing but in more important spots, like gedlee does in his closed box designs.

The Furybox is a Th and not a FLH.
A FLH will not be affected by a solid brace in mouth like a TH. The TH is effected due to the reverse wave path being altered. It has to be EXACTLY in phase with the forward wave at mouth exit.

And korny.
One day i am either going to build that SS modular you listed or the Rubic Horn.

Question is what are you trying to accomplish in your design. Your design looks pretty much same than mine Fostek speakers witch were build in 80's. Those speaker had effiency around 120 db.
