I'm not sure this will help much but here goes. The APT:200 is shaped like a JBL 2344. The APT:80 is a small round conical horn with 80° pattern. APT:150 is a rectangular CD horn with 100°x50° pattern. The 80 and 150 cost about the same, and the 150 is a little more. All of 'em are designed for 3.5kHz minimum.
