What's new about the M200MKIII one might ask? What isn't. Everything has been changed with the exception that the design still includes the same German fiber dome tweeter as previous revisions. A brand new long-throw woofer was designed to take full advantage of the increased power output allowing for deeper bass and a broader dynamic. The amplifier was completely redesigned into a 4 channel amplifier by-amping the tweeter / woofer in each cabinet separately while supplying twice as much power as the MKII with an impressive 120W RMS nominal power. The old crossover design was removed in favor of an active filter design.
