Though I haven't heard of that exact model, it's probably a lot closer to the newer "K" series than it is the old "D" series! You see, the "M" series is actually the replacement (read-newer model) for the "K" speakers. Heavy-duty, 200 watts, high efficiency ceramic magnet. I'd say it it's relatively comparable with the 1501-4 Black Widow...probably a bit more expensive, though!

The half-a-century old design "D" series JBL is it's own animal. Lighter, with a medium-sized Alnico magnet, thin paper cone, great tone...but not very efficient, when compared to modern speakers. Though the "D" series is still great for home use and recording, they usually won't stand up to the power required today, especially when used in opeb-back cabinets.
