Omen Def Mk.I-B is now fitted with our high-output nanotech driver and marked as one-bee [Mk.I-B] and we are making the drivers available to those that would like to upgrade their original Omen Def loudspeakers.
(Kit Price is for a matched 2-channel set of parts.)
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. Omen Def Mk.I-B has one very big difference over it’s predecessor, it features the Dominance developed nanotech high-output driver. There are no other changes but the difference is pretty huge—more resolution of bass, mids and treble, more resolution of tone and texture, and better dynamic handling of complex music.
Omen Def Mk.I-B Can Be Identified By Two Main Features:
- The revision Mk.I-B nameplate on the back of the speaker.
- The engraved model number in the full-range driver.
What’s In The Kit?
2x Matched pair (4x total units) of Zu103ND/G1-16 drivers (high-output paper-cored nanotech 10” full-range drivers factory burned-in for 600 peddle to the metal hours).
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 a refund.
Other Options Not Included In The Base Kit

How It’s Done
This is a very easy swap, and no soldering is required.
- Make sure you are button, snaps, belt buckle and wristwatch free.
- Switch off your electronics and disconnect your speaker cables.
- With a clean work space and a clean blanket or rug, lay it down with drivers facing up.
- Careful not to poke a hole in the cone or surround, remove the full-range driver fasteners.
- Remove the full-range machined trim ring and sit it aside.
- Grab hold of the machined center cylinder of the driver and lift it up, or use the rim.
- With it just clear of the cabinet cradle the driver from the backside with your other hand.
- Remove leads by gently rocking the connector longitudinally and pulling.
- After all leads are disconnected from the full-range driver set it off to the side.
- Now move the new FRD into position, connect red to (+), black to (–) then fit the FRD.
