Romy,

I have made honest attempts to contact the recommended horn designer candidates, but with no result. I do not know why but it looks like they are not seeing me, or responding. Like walking down the street and observing pedestrians looking though me as if I am transparent. I have to do this project on my own now but I am not informed or knowledgeable. So I would like to ask for some guides from those who can share their knowledge:

I have an idea of my available space. It is maximum 36" deep for the horn flare. I have additional space for the back chamber. I have more flexibility in the mouth size, it can be made quite big if necessary, up to 34" x 30", or alternatively 30" round.
I have listened to various 12" and 10" drivers, just for fun, without mounting in a box. Always, the 10" drivers sounded better in my opinion. The word "better" will require a separate thread for explanation, but in short, they are cleaner. So my preference is to use a 10" driver if possible.

What changes in the horn dimensions between 10" and 12" driver?

Lower cutoff will be dictated by design, I have no requirement as long as its below 150Hz.

Will anyone be able to understand my situation and help out? We'll see.

Herman
