The E3 is an extremely small and versatile high performance system with astonishing sound and excellent headroom. The horn, which may be rotated to give either 90° x 60° or 60° x 90° coverage, has the necessary flexibility in directivity to enable a variety of applications such as delay, infill or distributed sound reinforcement applications. In addition, it can be used as an extremely compact stage monitor. Together with a subwoofer system the E3 is also capable of reproducing live or playback music at continuously high SPLs.
