Signature Sound Synopsis
The OMD-28, along with the entire OM Design Series, not only represents the world’s first high-end Omnipolar® loudspeaker lineup; it’s also the pinnacle of Mirage sound. When a speaker is Omnipolar, it works with the room to create the proper proportion of direct and reflected sound, resulting in immersive, true-to-life performances.
Two 8-inch multi-layer woven carbon fiber woofers mated to patented Ribbed Elliptical Surrounds—which eliminate distortion and raise efficiency—allow the OMD-28 to achieve outstanding bass extension. Two down-firing ports take advantage of the space between the bottom of the cabinet and the base to further enhance the speaker’s low-end performance.
A 5.25-inch multi-layer carbon fiberglass hybrid midrange faithfully handles the most significant part of the audible sound spectrum, resulting in precise vocals and portions of musical instruments that can sometimes be left behind in conventional designs. The chambered 1 1/8-inch titanium dome tweeter creates the speaker’s warm, rich high frequencies.
But what really puts this speaker above and beyond the rest is a patented Omniguide module, an ingenious design that involves two unique deflectors. While one deflector rests on top of the speaker’s tweeter, the tweeter itself is housed in a deflector, suspended over the midrange. These combined elements distribute sound directly towards the listener, as well as reflect it off walls, ceilings and other surfaces—resulting in a perfect 360º soundstage. More importantly, you’ll hear the same enveloping performances from anywhere in your room.
