Minimal Appearance, Maximum Performance

Power from Above Our entire Omnican Series could easily be considered the most spacious–sounding in–ceiling speaker lineup on the market. And when it comes to the OC–45–the smallest model in the series–there's no denying it's one tiny but tough performer.

A powerful 4.5–inch titanium deposit polypropylene woofer with patented Ribbed Elliptical Surround technology lets you experience satisfying bass performance with true depth and near zero distortion, while a 1–inch pure titanium hybrid tweeter generates warm, rich high frequencies.

But what really separates this speaker from competitive designs is a rotating patented Omniguide module, an ingenious design that involves two deflectors. While one deflector rests on top of the OC–45's tweeter, the tweeter itself is housed in a deflector, suspended over the woofer. 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.


Designed with performance, style and versatility in mind, our Omnican OC–45 speaker delivers immersive, uniform sound that's impossible to achieve with conventional in–ceiling designs– meaning you can reduce the number of speakers required for a distributed audio application.

Great for indoor and outdoor use, the discreet OC–45 perfectly integrates into your lifestyle. Whether you're entertaining in a home theater room or relaxing on the front porch, this versatile speaker evenly fills your entire listening area with enveloping performances.

The OC–45 hangs slightly below your ceiling or eave to maximize the benefits of its patented Omniguide technology, which is responsible for creating the enveloping 360º soundstage. Furthermore, the Omniguide rotates so you can fine tune the sound specifically to your area.

A paintable, low–profile grille and bezel further ensures that the OC–45 provides unobtrusive installation. Its weather–resistant construction provides whole–house audio performance, including high humidity areas. An included back–box provides uniform tonal balance independent from the mounting position. The back box is also removable for space–restricted installations.

This low–profile speaker is ideal for complete multi–channel dedicated home theater systems. Its even sound dispersion allows for perfect blending when combined with a Mirage subwoofer placed on the floor. Additionally, the OC–45 is voiced to match our Nanosat™ Prestige, Omnisat™ v2 and OMD–5 speakers, allowing for a variety of mix–and–match systems.
