you're right. "Trying to make up my mind hell" was where I was. partly because of my lack of familiarity with any of the proposed solutions (here or on other furims). But, corner horns are what I originally had in mind and once I sorted through all the "noise", the corner horns are probably the best solution. The only issue now is that I want to have a clean front face, meaning that I don't want the speakers to look like 3 separate boxes. I'd like to build them with a contiguous front face. But I'm not sure how to do that since the midrange driver is enclosed in a box that is wider then the bass box. If it where a ported enclosure, I could change the box dimensions to be a bit deeper. But in this case, making the box narrower will change the horn dimensions.
Any suggestions?
