Event Opal Biamplified Nearfield Studio Monitor

The Opal series monitors are a long awaited feat that combines numerous patented technologies that the people at Event have been meticulously designing and developing for years. The Opal Monitors boast a world class 2-way driver design and the EX8 driver uses a high-power neodymium motor with a 30Hz-10kHz response that blows away the competition. Incorporating their own ULD tweeter with rotatable wave guide mixes beryllium with the neodymium motor pushing powerful, high SPL sound minus the distortion that would occur in an inferior tweeter. The next level of monitoring, brought to you by Event.

Event's Opal Studio Monitors can be switched from a vertical to a horizontal position (the tweeter and logos rotate) to accommodate a variety of setup situations. All controls are concealed on the front behind a flip-open panel, and the amp is mounted on the back and designed to be low profile for better mounting flexibility. Front porting allows for more positioning flexibility - in soffits and more! The high-fidelity analog circuitry ensures the purest sound and a microphone is included for room analysis and optimum system configuration.

- Second dedicated voice coil

- Linearized impedance and reduced inductance

- Dramatically lowered distortion characteristics

- Increased speed and control of cone assembly

Event paid close attention to the Opal's cabinet and bass port design to deliver top quality. The Opal wears aluminum for reduced resonance and features a complex curved body to minimize the diffraction issues that arise from flat or cornered sections. It sports front-mounted variable impedance bass reflex ports that neither rely on room acoustics like rear ports do, nor suffer from air distortion artifacts like you find in conventional front-ported systems. The result is extremely fast, deep, and accurate bass.

Power
Offering 750 watts of power, stunning transient response, and general no-compromise engineering, you can expect an extended midrange, a surprisingly powerful low end, and an exceptionally precise and articulate sound with these amazing new reference monitors.

Drivers
The Opal is loaded with an EX8 driver that boasts a 30Hz to 10kHz raw response and a carbon fiber reinforced cone for big sound - all powered by a 63mm neodymium motor. The ULD tweeter sports a powerful neodymium motor that drives an edge wound aluminum coil on a beryllium dome. The tweeter can be rotated, allowing for either vertical or horizontal positioning of the monitor speaker. A second dedicated voice coil - named XCoil - is equipped for linearized impedance and reduced inductance and exhibits dramatically lowered distortion characteristics and increased speed and control of cone assembly. The end result? Amazing sound quality.
