ES Series

 A truly scalable system, it is compact and modular, with all the electronics and amplification housed in separate, portable units – the EPAK 2500 and 2500R. Placing the active electronics package outboard results in a lighter, easier-to-handle system with much more flexibility. Its compact size reduces transport costs, and either ground stacked or flown, it is quick and easy to set up, cutting labor costs dramatically. The EPAK 2500/R control unit incorporates four amplifiers. Electronic crossover filters, time alignment, equalization, system protection, and level controls are all done onboard, utilizing industry-leading 20MHz digital conversion where required. 


The ES1.0 Mid/High speaker and the EPAK2500/R make up the core of the amazing-sounding, incredibly dynamic ES system. Each ES1.0 requires an EPAK2500/R to power it and the three-way cabinet includes a 12” horn-loaded mid-bass driver, 6” horn-loaded mid speaker, and 1.75" Titanium compression driver. You can rotate the ES 1.0 horn assembly in order to run the system in a vertical or horizontal configuration and couple two ES1.0 cabinets together horizontally to create a very powerful, long-throw solution.

As well as driving the three-way ES1.0 cabinet, a fourth amplifier channel in the EPAK2500/R control unit is dedicated to powering a choice of ES series subwoofers. The ES1.5 is a lightweight single 15” enclosure, the ES1.8 a horn reflex, single 18” subwoofer, and the ES2.5 /2.6 a double 15”, twin asymmetrical design, available in either four Ohm (ES2.5) or eight Ohm (ES2.6) versions.

Simple to set up and use The ES System has been designed for plug-and-play operation. It would take a dozen or more outboard components, sophisticated measuring equipment, and a degree in acoustic engineering to achieve the optimization we’ve built into the EPAK 2500/R. A multi-position switch allows you to select from various subwoofer combinations; you decide which plug-and-play bass modules you want to use, select and go.

The meticulously designed control electronics inside the EPAK2500/R constantly monitor and preserve the relationship between each amplifier and component, delivering exactly the right amount and type of power throughout the system. When you’re able to perfectly match an amplifier with a transducer, you start to unlock incredible performance that is impossible to achieve with passive systems. Total system reliability increases dramatically, as does sound quality. With this kind of precision and efficiency built in, you’ll be amazed at the quality, depth, level, and resolution produced by an ES system.
