I like the M3's midrange. The M3's have a pure midrange which I attribute to the lack of a crossover. The M3s have a cap to protect the tweeter from low frequency signals but the driver is mechanically rolled off. The Reference de Capo speakers also rely on the natural roll off of the driver. They are expensive and interesting speakers.

M3s? I'm a fan.
