FE206E efficiency
I'm sure this is common knowledge amongst horn enthusiasts, but how much does putting a driver in a back loaded horn increase efficiency? Specifically, what efficiency will a Fostex FE206E (96db) have in the suggested back loaded horn?

Bueller... Bueller... Anyone... Anyone?
BTW, I'm planning on building the backhorns with 3/4" birch ply, but of course the plans are in metric. I know the volume of the area behind the driver is pretty important, but are the other dimensions so critical? Anyone have experience building these using non-metric ply? http://www.madisound.com/pdf/fostexcabs/206e_encl.pdf

i think you dont have to worry about the conversion so much the important thing is ratio of trought to mouth and if its the same trim-off in the conversion to both then it should be fine.
I was thinking about building the recomended enclosure to until i heard about the HDT from decware. They are easyer to build and well just read the reevues.

Re: FE206E efficiency

the efficiency in the mids and highs should remain largely unchanged @ 96 dB
