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.
