This monitor is designed for big power and incredibly low levels of distortion.

The Event Opal is an eight-inch two-way powered studio monitor that has been designed from top to bottom to enable the reproduction of the most detailed dynamics while delivering incredibly low levels of distortion. Its woofer, tweeter, amplifier and cabinet all feature innovative and unique design and technology elements, combining to create one of the finest studio monitoring systems ever released, and certainly one of the most important studio recording advancements of the last decade.

The Opal's EX8 driver provides a raw response of 30Hz to 10kHz and a power handling of up to 1000 watts. A high-powered neodymium motor provides 36mm of linear excursion to the bespoke high-strength glass fiber polyamide cone. Event's X-Coil technology dramatically increases the driver speed and control, lowering distortion to levels previously unavailable in its class, and providing defined and accurate mid range reproduction as well as powerful, high speed bass.

The ULD1 tweeter combines ultra light and rigid beryllium-copper with an extremely powerful neodymium motor to produce unbelievable high frequency clarity. The active monitor is mounted in the Opal's innovative high frequency waveguide, which has been designed not only to provide excellent stereo imaging and a wide soundstage, but also to enable users to remove and rotate it for accurate reproduction in horizontal mounting applications.

The Event Opal's cabinet is molded from aluminium to provide strength and minimize resonance. Each surface is a combination of complex radii to eliminate any diffraction inside the speaker cabinet. The front mounted ports incorporate a variable impedance design that completely remove any port noise, and does not rely on room acoustics unlike rear porting solutions.

    Comments about Event OPAL 2-way 750-watt Active Monitor:

    Powerful & revealing, these monitors accurately depict what I record & mix. They expose subtle changes in all forms of signal processing, making it easier to make the right decisions for tracking, mixing, & mastering. There are many reviews & opinions around concerning Opals; I leave it to others to talk technical issues. I just think these are some of the best sounding studio monitors I have ever heard! If you need a great set of speakers, these must be considered.
