Yep actually both the hf and the mid horn has to go out. But that makes it possible to access everything. Slightly tedious if it had to happen often but hopefully I will not blow the drivers on such a regular basis that this becomes a problem.
Someone contacted me about 3 months ago to design one.
I worked on it for a little while.
I dont like the concept as they are more omnidirectional anyway.
Plus I would rather have two HD for one hornloaded top.
I also like more modular system
but here ya go....
These were just the beginning stage and dimensions are definitely no longer the same.
