Zu Audio Offers High-Output Nanotech Drivers Upgrade Kits

July 19, 2012

Last month we announced that we’re fitting our high-output paper-cored nanotech drivers (developed for Dominance and used in Definition Mk.IV) in our Soul Superfly [Mk.I-B]. Now we announce that those same stunning drivers are being offed for Soul Superfly and Omen Def owners in an upgrade kit. (Shipped sequentially in order recieved. All drivers recieve a full 600 hours of burn-in and are not shipped prematurly, even if requested.)

Those living outside the U.S. will simply email [email protected] to coordinate shipping. If you purchased your Soul Superfly [or Omen Def] directly from us in the last two months we’ll swap you out for free, you just have to pay shipping. Here’s the prorated purchase schedule:

Omen Def

Since there’s twice the number of drivers in the Omen Def over the Soul Superfly, you simply double all the prices, refunds too. The difference the driver upgrade makes on Omen Def is simply amazing. On a technical level, it takes the effeciency up from 97dB to 101dB (1W/1m) and brings the impedance up from 6 ohms to 8 ohms.

Hype and Detail

The most important element of a loudspeaker is the driver—the round part that vibrates and turns electric power into sound. And when a loudspeaker is built around a full-range driver like ours it makes the driver all that much more critical. Soul Superfly Mk.I-B has one very big difference over it’s predecessor, it features the Dominance developed nanotech high-output driver. Same goes for Omen Def Mk.I-B which we are also now in production. There are no other changes but the difference is pretty huge—more resolution of bass, mids and treble, more resolution of tone and texture, improved presence, and better dynamic handling of complex music. And with Omen Def, you are also getting a 4dB gain in effeciency!

Soul Superfly and Omen Def Mk.I-B can be identified by two main features:

the revision Mk.I-B nameplate on the back of the loudspeaker
the engraved model number in the full-range driver

With the fitment of the driver upgrade kit you are taking your Soul Superfly or Omen Def to the Mk.1-B spec’ and recieve the identifying nameplate.

So, What’s in the Kit?

• 2x matched pair Zu103ND/G1-16 drivers (high-output paper-cored nanotech 10” full- range drivers factory burned-in for 600 peddle to the metal hours.) (4x in the case of Omen Def kits.)
• 2x Rev.B nameplates to be applied to the back under the binding posts.
• 1x Torx® screwdriver.
• 1x Purpose built packaging. To ensure the safe return of your old drivers you must repackage the old ones the same way the new ones were packaged. If they’re not, and damage results you will not receive the $200 refund.

HOW IS IT DONE?
(This is a very easy swap and no soldering is required.)

1. With the loudspeaker standing up: (laying the speaker down makes this a bit more difficult, with more risk of marring the finish.)
2. Loosen all the Torx-head stainless screws a few turns each.
3. Then remove all but one (x7) leaving one of the top screws in-place.
4. Hold the bottom of the driver frame and now remove the top screw and trim ring.
5. Allow the driver to slide down a few inches, magnet/driver basket hanging on the edge of the baffle hole.
6. Cradle the driver with one hand and disconnect the connectors with the other. (Wiggling the connectors back and forth longitudinally will help in removing these very snug connectors.) Then set the old driver down and out of the way.
7. Position the new driver Zu103ND/G1-16 sans trim ring with it’s terminals in the same position as old one was, reconnect red leads to + terminal, and a bit of longitudinal wiggle will help them seat. Then let the driver hang in the hole while you get the trim ring, screws and screwdriver.
8. Position the trim ring on the driver, put one screw through one of the top holes of both trim ring and driver.
9. Lift the speaker driver up, careful of the cabinet finish and the screw point, and position the screw in one of the top screw holes, then screw it in several turns.
10. Screw in the other seven, then torque all eight in stages, you want them pretty snug, about as tight as an average man can tighten them with one hand.
