General
The E18SW is a high-performance, direct radiation subwoofer with a single 800-watt, 18-inch woofer that follows the same robust design as the E series' full-range speakers. It produces bone-crunching lows as part of a PA system or deliciously hard punches during high-level dance music. An M20 pole socket is built into the top of the E18SW in order to easily mount the included speaker pole for placing the E10, E12 or E15 on top. Because the subwoofer weighs 43kg, attachment points for optional caster wheels are included for easier transportation.
The E series from QSC
This series is specially designed for the entertainment industry, which is what the E stands for. The whole series is about quality and ease of use which is why it's designed to work with almost any professional amplifier. QSC's own PLD or GLX amplifiers and the QSC TouchMix will get the very best results, of course. That means you can make full use of the DSP processing on this equipment. QSC has even included advanced DSP settings so that you don't have to do everything yourself. This ensures that you can get the very best performance out of the E series that delivers the same power and superb quality QSC's K series is known for.
