Value-packed Passive PA Subwoofer

Add an affordable subwoofer to your PA rig with the QSC E18SW. This 18" passive subwoofer turns 800 watts (RMS) of amplified signal into chest-pounding, dance-floor-driving powerful bass tone. Since it's designed for 4-ohm impedance, you can comfortably drive this sub with a modest amplifier. Thanks to its threaded M20 pole socket, the E18SW is also an ideal complement to your E series 2-way PA speakers, and it's built with the same touring-ready toughness as the rest of the line. What's more, you can easily add a set of casters to the bottom of the E18SW to make load in and load out as smooth as possible.

Get more from your E series speakers with QSC gear

While E series speakers are compatible with most professional PA equipment you buy from Sweetwater, we've found that they really shine when you couple them with the right QSC gear. QSC's PLD and GXC series amplifiers include special DSP settings that optimize them for use with E series speakers. What's more, if you have a TouchMix live mixing board, then you can use virtually any power amp out there and still tune your system to get the most out of these affordable speakers.

QSC E18SW Passive PA Subwoofer Features:
  • Tough, affordable, and powerful 18" passive PA subwoofer
  • 800-watt/4-ohm power handling accommodates modest amps
  • Threaded M20 pole socket lets you mount satellites and top boxes
  • Attachment points let you add optional casters for easier transportation
  • Tough plywood construction holds up to touring applications
  • An ideal match for your TouchMix or PLD/GXC amplifier
Beef up your low end with a QSC E18SW passive subwoofer!
