Overview: The Mirage OMD-28 is a tower speaker that
uses sophisticated driver technology, Mirage's exclusive OMNIPOLAR technology,
and elegant cabinet design to make the speaker ideal for the listener who has
floor space for a full-range tower speaker. The speaker is available in a Gloss
Rosewood and Gloss Black finish.
Note: The speaker is sold individually; not as a pair.
Applications: The OMD-28 is a versatile tower speaker
because it is full-range and can be used as a front main or surround speaker.
You can use this speaker to help create a complete home theater speaker system
or a dedicated 2-channel stereo setup.
Voice Matching: This speaker can be matched up with Mirage's
OMD-C1 or OMD-C2 center channel, Mirage's OMD-15 floor standing speakers,
Mirage's OMD-5 bookshelf/satellite speakers, and Mirage's OMD-R rear surround
speakers to create a home theater speaker system.
OMNIPOLAR Technology: This technology radiates sound in a
perfectly spherical dispersion pattern, expanding the sweet spot to encompass
virtually the entire room. OMNIPOLAR technology uses natural room reflections to
create a greater sense of realism. This is accomplished by recreating the same
ratio of direct to reflected sound (70% reflected/30% direct) that is typically
found in performance spaces. A conventional speaker only produces 30% reflected
sound. It is the additional reflected sound provided by a Mirage Omnipolar
speaker that creates a three-dimensional sound experience in your home.
Drivers: The drivers used in the OMD-28 are as follows and
are separated into two cabinets (one sealed cabinet and one ported cabinet):
- Sealed Top Section:
- Tweeter: Floating above the midbass is a precisely
angled cast aluminum OMNIGUIDE module that houses the speaker's
proprietary 1.1" titanium dome tweeter.
- Midbass: The speaker features a 5.25" multi-layer
carbon fiber/fiberglass hybrid cone midrange driver located on top of
- Ported Bottom Section:
- Woofer: The speaker features two 8" multi-layer
carbon fiber cone woofers with a ribbed elliptical rubber surround
mounted in the front of the cabinet.
Enclosure: The cabinet is made of very solid inert medium
density fiberboard (MDF) which creates a solid, flex-free cabinet which
eliminates music altering distortion. The enclosure is divided into two
sections. The enclosure uses a sealed section at the top of the cabinet for the
Tweeter and Midbass driver to provide clean and accurate reproduction of high
and midrange frequencies. The bottom half of the cabinet uses a down firing port
design (dual ports) used to help the front-firing woofers produce louder, lower
Speaker Terminals: The OM Design Series tower loudspeaker features
high quality gold plated binding post connectors that will accept a variety of
connector types including bare wire, spade lugs, banana plugs (single only), or
pin type connectors. The OMD-28 is equipped with 3 sets of binding posts which
allows the speakers to be tri-wired/tri-amped, bi-wired/bi-amped, or
traditionally connected to your amplifier. The tweeter's terminals are on top,
the midrange driver's terminals are in the middle, and the woofer's terminals
are at the bottom. Gold plated shorting straps are factory pre-installed, one
strap to connect the three negative and one strap to connect the three positive
Spiked Isolation Feet: The Mirage OMD-28 includes four machined
aluminum spiked feet which provide secure placement and helps to tighten the
loudspeakers bass response. The four spiked feet screw into the bottom of the
speaker and can be adjusted to level the tower speaker with your floor.
Placement: For best stereo imaging, the left and right speakers should
be the same distance from their respective sidewalls. If the distance from one
speaker to the listener is very different from the other it can affect the
soundstage or stereo imaging. Therefore, the ideal position is having the
speakers equidistant to the listener. When choosing the position for your new
speakers, try to avoid walls with predominately glass surfaces, as they might
not be the best choice for placement. If it is unavoidable to position the
OMD-28s close to a glass wall or a large window, it may result in a hard sound
with too much reflected information.
Note: A general guideline for speaker placement is to set up the
space between speaker and listener at approximately 1.2x to 1.5x the
distance between the speakers. For example, if the speakers are ideally
placed a minimum of 6' apart, the best seating position would be 7.2' to 9'
Break-In Period: It is vital that the OMD-R speaker be
allowed to break-in properly before you perform any precise set up procedures,
system adjustments, and before you play it at higher volume levels. The best
method of performing the break-in is to play a full range musical passage at a
moderate level as long as possible. Utilizing the repeat function on your CD or
DVD player can assist greatly. Optimum sound will not be achieved until
approximately 100 hours of playing time. After break-in, the volume level can be
increased. Do not play the speaker at high levels until the break-in process has
been completed. The drivers need to "loosen up:, and until this occurs, damage
can result to the drivers.
