I just grabbed four 2202H from a estate sale, the guy is stripping all the valuable drivers and ditching the worn out cabinets.
These 2202H are in very good condition (I removed the dust foam right away before using them, good thing I did, it had already started to break down) but I noticed they have marks on the back, and not on the front, indicating they were rear mounted.
By curiosity, does anyone can think of any JBL system having a rear mounted, most probably horn loaded 2202H....?

Any ideas?
