campo, if I were you, I definitely would consider soffit mount for this kind of serious large monitors. I haven't done it, but I always want to do it... The work itself would be simple, butI have to empty the room before doing it. Have you ever read soffit threads at Johnsayers?

No, but I agree that soffit mount is the one the best options. I tried to build looking future forward though I intend to try this at near field, It should have enough output for far field. I'd like to think that one day I will own a house where I can build a room specifically for my audio task's and pleasure. Soffit mount would definitely be the way to go.

I agree. Your component choice and design should do that well, I'm looking forward to seeing the progress and results. Soffit mount is a good idea.

Is it possible to cover the whole spectrum, high spl, low distortion with a 2-way?-theoneetractrix-jpg

I didn't try a mock directivity model for the horn...was more interested in if I could make a decent looking crossing. Looks ok I guess. With the low pass shelf to create a flat response on the 350hz tractrix and a 381hz 2nd order LR the excursion remains very low even near 115dbit peaks around 0.12mm....

This is the unequalized response I got for 350hz tractrix but I don't know how correct it is.

Here's an example of a 3" diaphragm, 2" exit driver mounted on a short(ened) horn. The driver's exit angle is 34.7°.
Hi Rob, wow, that is impressive response in the top octave! What CD is that?

Kind regards,
Mitch
