Product Research



Overview: The Mirage Omni-S8 is a compact powered subwoofer that features an 8" woofer and a 100 watt internal amplifier.

Ribbed Elliptical Surround: The Omni-S8 features a woofer with a Ribbed Elliptical Surround, which is a proprietary component that has been designed to increase excursion, eliminate distortion and raise efficiency. This feature eliminates any surround dimpling so this subwoofer can play lower with greater output and fidelity.

Bass Reflex Cabinet: The down firing port of the Omni-S8 increases output without port noise, using the floor as a loading surface to augment the yield of this unique subwoofer which allows the subwoofer to deliver natural and lifelike sound.

Amplifier Section: The powered subwoofer has a built-in 100 watt RMS internal amplifier.

Driver: The Omni-S8 feature a front firing 8-inch titanium deposit hybrid woofer with a ribbed elliptical surround which performs like a much large subwoofer and has a frequency response down to 27Hz.

Status Indicator: The LED found on the front panel will illuminate when the subwoofer is connected to an AC source and when the unit is active. The LED will display in red when the unit is plugged in but is not receiving a signal and will display green when the unit is receiving a signal.


Front Panel Controls: The powered subwoofer uses front panel controls to make it easy to adjust the volume and crossover at any time.

Subwoofer Level: This knob can be adjusted to control the level of output from your subwoofer. The level chosen should allow the subwoofer to blend its output with that of the rest of your audio system.

Frequency Control: This control allows for the adjustment of the low-pass filter. Adjustments can be made from 40Hz to 120Hz. This will determine the highest frequency that the subwoofer will play.

Phase Control: This switch allows for the adjustment of the phase of the subwoofer, in relation to the speakers used in your system. You can choose either 0 degrees or 180 degrees.

Filter Mode: This switch allows for the selection of either "Filter On" or "Filter Off". Choose "Filter Off" when you are using a receiver with a dedicated LFE out that has its own crossover filter.

Power Mode: This is the only control function that is found on the rear panel. This switch can be set to either On, Off or Auto. If the switch is in the Off position, the subwoofer will not power up. If the switch is in the On position, it will constantly remain on. When the switch is in the Auto position, when a signal is present the subwoofer will turn on and when will automatically turn off several minutes after a signal is no longer present.


Sub Input: This input is an RCA type mono input that will be hooked up to your receiver's subwoofer output.

High Level Input: These are spring post type speaker connectors. The high-level inputs are designed to be used with receiver or amplifiers that do no incorporate any RCA type subwoofer outputs.
