Yes you are correct. The taller two 15" cabinets with the horns were PA cabinets, and the speakers used were 16 ohms each so the total is 8 ohms. (if you count the T&R would be 27) The shorter guitar cabs with the horns would be (23 T&R) and use 8 ohm speakers for a 4 ohm total impedance. So counting the T&R is an easier way to tell what speakers are in the cabinets. This is of course only valid if the original speakers are in the cabinets.

The reason, the K200, K300 and K600 PA heads, the power amps run at 4 ohms. Two 8 ohm PA cabinets presented 4 ohms to the PA head.

The shorter guitar horn cabinets were designed to run 4 ohms. The K250 head is designed to run only one cabinet at 4 ohms. The K250 amps only had one speaker output jack so if you wanted to add a second cabinet, the second cabinet would have the power module in the back of the amp, so the power cabinet was running with it's own 4 ohm amp.

The model number 2K+1H the K may be a later model where the K replaced the G.

If your goal is to use the horn cabinets as PA cabinets, I'd repace the 8 ohm speakers with 16 ohms.
