ZU DEFINITION MK IV REVIEWS

.

Zu has always put bang for the buck into every product it has made, and Definition is a very visible expression of this design philosophy. Expensive? Sure, but consider the competition’s and you can see the values inherent in Zu.

Sean brought the big Zu Definition Mk IV. This thing is a marvel – 101dB/W/m sensitivity, 8 Ohms, and clean extension all the way to 14 Hz, courtesy of its built-in subwoofers. To me, the new drivers have kicked up the sound quality a notch or ten, and on this new Definition, there is an effortless, powerful feeling that no amount of wordsmithing on my part is going to make you believe.

ENJOY THE MUSIC

For roughly the same price as the old model, the Zu crew has managed to completely rewrite the book on this speakers it seems. All new drivers and cabinet design make for an incredibly compelling upgrade that is at once more open, dynamic and transparent than the already not too shabby old model. Consider this the shortest penned preview of its kind, I have been promised a pair by Christmas. No doubt, this speaker will turn heads and ears. Folks, save up, this is one killer speaker.

POSITIVE FEEDBACK

The Zu Audio Definition Mk. IV speakers kicked butt! They had the power to physically connect the listener with the music. These speakers don’t just play loud, they let you feel the music’s power in a way that few high-end speakers ever do. They just sounded better and better the louder I played them. The new Zu Definition Mk. IV is superdynamic, a real party speaker.

The new Zu Definition Mk IVs sounded huge and pumped so much musical energy into the room the good vibrations carried all the way into the couch I was sitting on. A musical massage and a nice reminder that this is all about music which all about having fun.

The Definition was conceived and launched in 2003, and has earned a huge amount of critical acclaim over the years. Blue Moon Award from multiple 6moons.com reviewers, Writers’ Choice Awards from Positive Feedback, not to mention the great press from international audio magazines in Hong Kong, UK, Germany, Hungry, New Zealand, China, Russia, Finland, Sweden, Brazil, Japan, Vietnam, Singapore, Spain, Norway….

Here’s what Postive Feedback had to say about the Definitions MK II’s

“If riding an F430 at breakneck pace through your favorite Malibu canyon road is the idea of an ultimate car control, then listening to Meeting by the River, a Kavi Alexander/Water Lily Acoustics recording [through Zu Definitions] must be the audiophile equivalent. The intricate interplay of only three or four instruments within the confines of Santa Barbara’s St. Anthony’s Seminary Chapel is an exemplary demo track for the Definition Mk2s. Transient responses are off the charts. The dynamic swings, multi-layered instrumental colors, and tones are a test for any loudspeaker, yet, the new Zu loudspeakers don’t even begin to break a sweat. Perfect downshifts, you hit the apex and slam the throttle-until you are ready to do it again at the next turn. That about sums up the experience you get when the Definition Mk2s play this track.”

Introducing the new Definition Mk IV

Definition Mk.IV is both an evolution and a clean-sheet redesign—everything that was good is now even better, with the transition to a down-firing sub’ and rack-style integrated bass amp being the most obvious evidence of that redesign.

Performance benefits include a significant refinement in full-scale integration with notably expanded dynamic range and heightened expression.The Mk.IV resolves even more transient and micro-detail yet is denser in tone, richer, and more expansive of scale and image. It’s Definition realized and come of age, delivering stunning dynamics and real fidelity, and all with peerless ease and fluidity.

Tone richness and density, with a balance of power, scale, resolution and intimacy that allows you to melt into the music. The majority of the engineering and fabrication excellence of Dominance is found in Definition Mk.IV; Zu’s nanotech impregnated full-range driver and massively motored 3″ [76mm] bi-film composite tweeter, the same developed for Dominance. And for nearly as impressive as Dominance bass performance, Definition Mk.IV makes real descending subterranean bass energy real through a very efficient integrated 12″ [31cm] sub-subwoofer.

The cabinet of Definition is a super structured design with reinforced baffle and base. Within Zu has implemented their Zu-Griewe technology and have tuned the FRD to extend even deeper. Definition engineered to fully realize and showcase Zu’s innovations and position on tone within a loudspeaker system that represents real value within the high-end and looks great in normal living rooms.

Definition History

  • 2003, original Definition was released.
  • 2003, Audax informs us that they can no longer produce the super-tweeter we are using as they are closing their French production of drivers. We scramble to finish the driver lens we had been working on.
  • 2004, Definition Mk1.5 is launched with new ZuT1 super-tweeter. No other changes to the design or manufacture of the loudspeaker hence the 1.5 designation. Addition of iridescent and matte finishes. Matte finish is a true matte, but is rough like sandstone.
  • 2004, Definition Pro is launched as a “secret menu” item. Definition Pro, despite it’s adoption and solid sales, was never marketed to the home audio, or pro markets.
  • 2007, Fall, Definition Mk.II was introduced.
  • 2011, Summer, Definition Mk.III AND Defintion Mk.IV introduced.
