High Output Active-Driven Subwoofer

The ES2.6 (8 ohms) is a double 15", high-output subwoofer designed for the ES Series speaker system. Using new concepts in twin asymmetrical acoustic chambers, they deliver very high speaker loading and intense output from a relatively small cabinet footprint. Reproducing low frequencies with very high transient content, they are ideal for use in live applications or as part of a five way ES system utilizing VHD1.21 and 2.21 subwoofers. Together with the ES1.0 and EPAK2500/R, the ES2.5/2.6 delivers the highest dynamic range of any other comparable system providing new levels of clarity, depth, and resolution.


  • Professional, Baltic birch construction with a highly resistant polymer coating

  • 137dB sustained output 140dB peak (when using 2 units of ES2.6)

  • High acoustic loading via twin asymmetrical chambers

  • Two 15" low-frequency drivers with 4" (100 mm) inside/outside, epoxy-baked, high-temperature voice coil assembly

  • Four proprietary side handles for simplified handling and carrying

  • Heavy-duty front grille to work with the innovative new ES series magnetic carts

  • High-impact, low-friction feet are asymmetrically located on two sides allowing vertical or horizontal system setup, lock-in, and easy cabinet movement

  • Six industrial-grade internal corner braces with twelve M10 suspension points

  • M20 top hat for pole mounting applications

  • Weatherproofing option and special paint finishes available on request.


Specifically designed to accompany the ES1.0 as a true full range high output system for live performance and music 

  • Theatres

  • Houses of worship

  • Portable PA

  • Scalable into larger systems

  • Can be integrated with other ES subwoofers
