Definition Mk.IV is designed to give its best performance in midsize and larger rooms, matching up best with good sounding amps, tubes or solid-state. Definition Mk.IV distills everything we’ve learned from creating our flagship loudspeaker, Dominance, into a loudspeaker within reach of mere mortals. Definition Mk.IV takes from Dominance our new nanotech full-range drivers, the fabulous Radian 850 based tweeter and our Event cable. It uses our Zu-Griewe acoustics technologies for the full-range drivers, and cabinet engineering that addresses noise and framework function across all fronts: materials, structural, bonding and building technique. The resulting combinations of engineered plate, hardwoods, damping compounds and metal alloys create a very inert structure.
