Product Overview

  • An 8-inch woofer with Ribbed Elliptical Surround brings music, games and movie effects to life
  • 240 Watts peak power for accurate reproduction of movie and music soundtracks

    The Lowdown

    ESW-C8 delivers tight, powerful bass response, adding excitement to your favorite music, games and movies. This hard-hitter delivers a whopping 240 watts of power. The ESW-C8 with its great looks adds class to any room—but with the way it performs, it only looks tame.

    Bragging Rights

    The ESW-C8 subwoofer offers terrific performance and great features:

  • Ribbed Elliptical Surround woofers that create high efficiency, low distortion
  • Down firing port extends bass response

    A bass-reflex design with a down-firing port, the ESW-C8 shakes things up with an 8-inch cone featuring Ribbed Elliptical Surround. This design eliminates surround distortion, so the ESW-C8 can reach lower, with greater output and fidelity.

    The ESW-C8 features line and speaker level inputs and has a variable low-pass filter that is continuously adjustable from 40Hz to 150Hz. A fully variable phase control from 0 to +180 lets you integrate the subwoofer with other speakers in an Energy system.

    Maximum Performance Tips:

    The three most common subwoofer locations include corners (which can result in boomy or exaggerated low frequency response), placement along a wall, away from the corner (producing moderate bass performance with increased fidelity over corner placement), or beside a front speaker (creating a better blend with the front speaker, but sacrificing overall volume). Experimentation with subwoofer placement is highly encouraged; slight adjustments can create big differences in sound reproduction. To test subwoofer placement, install it temporarily in your main listening position and walk around the listening room while playing a familiar piece of music until you find the best sounding position.
