Ronnie,

Very nice, though I do not know where you would like me to move the thread.  (It looks like it’s OK where it is). There are some comments that I might to pass.

You decided to go for a large MF driver. This is fine if you like it but I found that the entire Fostex idea and a large throat at MF horns do not work. Beside the obvious limitation of Fostex driver the large throat demand a large mouth. As the result the MF become oversized that incentive people go for lower cut of. In reality the Fostex should not be crossed as low and the mouth would allow. So we have a MF horn with “heavy mouth” and the sound kind of funny. In addition Fostex sound strange at thier HF. With a simple pop-jazz music it is not visible but with more serious classic they are losing. Not to mention that with no Fostex you would not need any back chamber at MF horn.

I might only advise you to try any simple and cheap compression drive with 1-2 out. It would make the MF horn way smaller and way simpler. Also it would allow you to locate it closer to your upperbass horn and give some space for a prospective tweeter….

One more thing. I detected that the MF horns are ridiculously sensitive to any objects located nearby with thier mouths, though they surprisingly do not really “see” the upper bass horn. So, after you finish your horn you might come up with some kind of harness the hold the horn in this position but do not act like a baffle.

Feel free to share your contraction techniques and the observations you will be experience while you will be teaching your horn to sound correct

PSL I hope you do not drive this with SS gear…..
