Omen Center Mk.I-B, what’s different?
• New nanotech Zu260FRD/ND full-range driver.
• ClartiyCap MR capacitor used in the high-pass network.
• Revised high-pass network values for better transparency and driver blending.
• Much tighter matched pair tolerances on drivers and electrical components.
• 600 hours of high intensity factory burn-in.
Omen Center Mk.I-B is the same as the original with a few nice differences and one huge. Mark-
one-bee is fitted with our nanotech sanctified composite paper cored cone. This new 10” full-range
driver uses the same great Zu260 motor assembly, and when combined with these new nanometer
materials and lay up gives the perfect combination of classic Zu tone and resolving transparency.
The change in capacitors is also a pretty healthy step forward in treble resolution, switching from
the PulseX to the ClartiyCap MR. And then the revision in the tweeter high-pass network for better
transparency and blending of our Omen series nanotech full-range driver and ClartiyCap MR.
Omen Center is designed specifically for center-channel applications, with vocal resolution and
natural presentation being the primary design goal. The Omen series represent the meat and
potatoes of what Zu is about, standardized and designed for high-volume loudspeaker production—
the only way to get this level of quality, performance, and good looks at this price. Our drivers,
machine work, cabinetry, finish, assembly, packaging, all done by us in Ogden, Utah.
Even though Omen series are our entry level loudspeaker, they are still built to last a lifetime:
cabinet material, adhesives, driver assemblies... every component is a high quality part designed to
perform.
OMEN SERIES TECHNOLOGIES OLD & NEW
Omen Center, like all Zu products, is built around the critical human voice (A1, 55Hz, through A6
and all the possible harmonics, to approximately 10kHz). Serving this critical region of tone is Zu’s
5th generation 260 standard motor 10.3” [260mm] nanotech/paper composite full-range driver.
And despite what many audio snobs might think about it based on price, Omen loudspeakers are
true state-of-the-art loudspeaker systems—two-channel stereo or multi-channel home theater.
FINISH
Standard finishes are top coated by UV protecting premium grade conversion varnish. All finish
work is done in Zu’s custom finish shop.

a stand or sitting on a shelf.

TIPS ON GETTING GREAT SOUND FROM OMEN CENTER
Omen Center loudspeaker now get 600 hours of factory burn-in, it will sound good right out of the
box but will not give you its best for several weeks, depending on how much play it get and what
kind of music it sees. If at first you find it restrained and a bit conservative, relax, it will come
around.
Zu Omen Center loudspeaker is sensitive to the cold. If you have received, moved or stored it in
cold temperatures it will take a week or so to again sound its best.

WARRANTY
Zu products are designed and manufactured to the highest quality. However, if something does go wrong Zu
will fix or replace the product free of charge. Zu Omen Center loudspeakers have a five year limited warranty
from date of purchase to original owner. If under normal home use you have any problems with drivers, cable,
parts, cabinet, we will fix or replace the product. Loudspeaker warranty and service can usually be performed
by the user, also known as DIY service, in such cases Zu will provide full technical support. This provides
faster repair of product (reducing down time is always good), minimizes handling hassle and damage potential
to both Zu and you, and reduces shipping costs.
Zu loudspeaker finish warranty covers color changes in paint, finish checking, and oxidizing. While we use
the highest quality UV protecting topcoat finishes, we cannot guaranteed against fading and you should keep
them out of direct sunlight, just like a piano. While every effort is made to ensure a perfect finish that will
last a lifetime, this warranty does not cover damage from impact and abrasion, or seam / core construction
visibilities in extreme high temperature / high humidity environments. Zu products are designed to be used
in temperature and humidity controlled environments, namely your home or office unless otherwise stated.
Warranty does not cover loudspeaker finish damage caused by the extremes of an uncontrolled environment.
If in the highly unlikely event that a Zu product arrives to you dead on arrival (D.O.A.), and after discussing it
with a Zu tech, we will ship another of the same product at our expense and arrange for the D.O.A. product to
be collected. If after inspection we find that you have misrepresented a returned product’s condition, and that
it was improperly handled or used, Zu will charge you for all damaged parts, labor, shipping and handling of
the product.
Warranty does not apply to damage caused by operating the product outside the intended use, accident,
another product, misuse, abuse, flood, fire, earthquake or any other external causes. Warranty does not cover
damage caused by modification or service performed by anyone other than a Zu representative. Cosmetic
damage is also excluded from warranty, as is all product that has any part of the Zu serial number removed.
When a product or part is exchanged the replacement becomes your property and the suspect or damaged
part becomes Zu’s property. Parts provided by Zu must be used in products for which the warranty service is
claimed.
WHAT YOU CAN EXPECT IF WARRANTY SERVICE IS NEEDED
If warranty becomes necessary, you must call or email for a return of material authorization (R.M.A.) number,
or to arrange for user serviceable parts. This provides opportunity to assist in diagnosing the problem and
helps us to schedule for rapid turnaround in the event that parts, service or repair is needed. Upon factory
inspection of parts or product, warranty eligibility will be determined. While service options, parts availability
and response times will vary, we do our best to keep you happy. International customers should know that Zu
will comply with all applicable export / import laws and regulations, you may be responsible for custom duties,
taxes, broker fees, freight, and other charges. When shipping of product or part is required, repackage the
complete product, or part, in its original packaging. If you have any questions about packaging please call or
email. Product damage caused from incorrect repackaging is not eligible for refund or warranty and the freight
company may also reject your insurance claim. Until we have the product back in the shop and sign-off that it
is eligible, the product is still your property, we recommend you insure or declare the full value when shipping.
We also recommend that you only ship with a freight company that has a good reputation and offers tracking
and insurance for the full amount.
