You know, it's funny you mention that. I thought the compression chamber was unusually deep, compared to most horns. I thought about stretching the height of the enclosure and putting a false wall in there to do exactly what you suggested.

If I did, would there be any problems moving the driver up to the (vertical) middle of the compression chamber? I see many horns do that, so I would think not.

That would help me on (a) overall cosmetics (b) driver getting closer to my preferred height for seated listening and (c) more room - vs the current design - to allow space to attach a grille frame in the area above the driver.

I had the right to remain silent. I just didn't have the ability. (Comedian Ron White)

Make the false wall at an angle... should be no problem shifting the driver up a bit.

I've tried FE103/FE103Sigma/FE108Sigma in the backloaded horn I posted yesterday in another thread, something about 'cool Fostex horns...'

At the moment I'm using FE103Sigma's in a 200Hz Oris103 fronthorns, these are prototypes from Bert Doppenberg. I'm using sand-damping on the plastic horn. On top is a modified Audax PR120i, below is a JBL K120 in a 50Hz horn.

The result is in no way comparable to a single backloaded 103....
