The EF500P redefines performance in a high-power professional active loudspeaker enclosure. Utilizing the popular élite EF508 as a base, and adding a total of 1000 watts (program) of bi-amped power and advanced signal processing, the EF500P is destined to set a new standard for active loudspeaker design. The woofer or low frequency amplifier uses Class D switching technology to reduce overall weight of the amplifier section. This solution allows the horn to produce loud clean transients to keep up with the high output of the woofer. The two-tier amplifier technology isn't typically seen in a product like this, however we found the advantages (lower weight, more efficiency, higher headroom and lower operating temperature) made it a perfect choice for powering the top end.

This combination of amplifier technologies keeps distortion to a minimum while reducing the heat dissipation to a level low enough to eliminate the need for heavy heatsinks for the overall power stage. As an additional advantage, our unique combination of two-tier and Class D amplification has reduced extraneous heat to the point that EF500P can easily be used in any orientation, and close to walls, floors and in close arrays with multiple cabinets. We have found that competitive active loudspeakers with large finned heatsinks need to be operated vertically and with clearance to ensure proper heat dissipation and ventilation. Since the EF500P is ideal for flying in large clusters and in point source concert sound systems, our designers took extra care making sure that in tight clusters overheating would not be an issue.

EF500P - Mixer / Amplifier Module
We've also found an opportunity to tweak the electronics for maximum overall speaker performance and protection. Borrowing some ideas from our powerful and popular TX Series PA systems, the limiters used in the input and crossover stages are a complex combination of gain reduction and sweeping filters. As the EF500P is being pushed to its maximum input / output levels, it's advanced filtering begins rolling off unnecessary subsonic frequencies. In addition the processing protects the individual components ensuring failure free operation even after long term operation at close to maximum output levels. The filter has remarkable (less than 70ms) response times, allowing the system to constantly be retuning itself to make sure the output is as clean, as loud and as clear as possible at any given moment. This is achieved without negatively affecting the overall sonic quality of the cabinet. This ensures that the essential part of any mix, like the vocals or solo instruments, come out clean and clear when the cabinet is being operated at the extremes of power and woofer excursion. Extremely fast and accurate limiting is in place to protect the speaker components.

The EF500P has a built in mixer allows the loudspeaker to be used directly with a microphone and / or line source. The loop output allows additional active cabinets to be driven from one cabinet's mixer stage, or a series of cabinets to be driven from one source. If desired, the end user can combine a pair of the EF500P's using the mixer inputs on each cabinet and coupling the loop outputs. In this simple example you would have the ideal presentation system with two microphone inputs, two line inputs optimized for CD, Cassette or laptop computer audio source, complete within two speaker cabinets. Many of our active cabinets can be linked together but a maximum of three 'mixers' can be active at any one time. (Making three mic sources and six line sources available in any three or more cabinet array). The microphone input has equalization and high pass filtering appropriate for vocal applications. The trim control allows looped cabinets to be individually adjusted in level. This is invaluable in applications where large numbers of cabinets are used such as clusters or in trade show applications or when EF500P's are used as repeater cabinets or for side fill. The 100 Hz high pass filters allows the EF500P to be used more efficiently with any active subwoofer.

Designed for maximum versatility, élite powered loudspeakers use a combination of proven amplifier topologies to deliver unmatched clarity and precision. Innovative input sections allow direct connection to virtually any line or mic level source. Simple integrated mixer and 2-band EQ allows quick set up and easy operation in any live sound application.

Rugged Driver Mounting System
All élite cabinets feature a specially reinforced driver mounting system that makes sure the horn drivers will still be attached to the horns when you get to the show. The ABS or composite horns are pressure fitted to the driver which is bolted to the internal driver support.

Custom Design Horns
Custom ABS plastic and composite horns are specifically designed for each cabinet and manufactured right in our factory for optimum quality control. This insures proper waveguide output for better clarity and lower distortion.

Curved Metal Speaker Grilles
Curved metal grilles absorb shocks evenly to resist dings and dents while eliminating frequency resonance. The trapezoidal cabinet shape allows for arrayable performance without phase cancellation.

Recessed Handles
All élite cabinets feature attractively recessed bar handles. Great care is taken to make sure that they "stay out of the way", but are easy to get at when you need them.
