The two or three times I have heard them (M-15), they have been out in the room, about five feet out and four feet or so from the side walls. I have not heard them in comparison with the 99's so I cannot offer any comparisons there. From my perspective, what I have heard, was not my cup of tea. Emphasis on the MY.
My ears heard too much of a disconnect between the horn and that BIG woofer, with a port big enough to stick your head into. The fit and finish is very nice though.
