Wayne,
I'm close to making up a pair of mid horns, but have a small problem. I need to finished width to be 24", including the outer
box they'll go in. I was reviewing the dimentions from your post 14408 and if I cut both sides and top/bottom to be 4.5" at the
small end, and butt joint them, the horn entrance won't be 4.5" square because of material thickness. In any case, if I need to
narrow the width slightly (~1.5"-2"), should the sides be angled
in to maintain horn length, or just shorten the whole thing a little?
Thx, Chris

You can scale it down a bit but please remember that an undersized horn becomes peaky. So scale it back as little as possible because even though the horn is physically large, it is acoustically small. I would be sure to extend the mouth right to the edge of the cabinet to get as much mouth area as possible.

Sorry to bug you again about this, but its OK ot scale in which direction? Plain width with no geometry changes, which translates to
shorter depth, or horizontal angle.
Thx, Chris
