QSC E118SW 18" High-Performance Direct Radiation Subwoofer, 800W, Black

For live performance and high-energy venues that demand authoritative low-frequency impact, the QSC E118SW 18-inch pro subwoofer delivers tight, room-filling bass that brings kick drums and bass lines to life. This QSC E118SW passive subwoofer pairs an 18" aluminum-frame woofer with 800W RMS capability and a 37 Hz low-end response to produce consistent, high-output low frequencies without mud or distortion. Its 4-ohm impedance and 98 dB sensitivity let you drive strong output from economical amplifiers, while the M20 pole socket and included speaker pole make sub/satellite configurations fast and reliable. Built for the road, the rugged enclosure, foam-lined perforated steel grille and optional caster attachment points protect your investment during touring and rental use. The E118SW also integrates with QSC GXD, PLD and TouchMix platforms so you can apply proven DSP tunings for FOH, stage monitor or dance music applications. Beyond live sound, the subwoofer is equally useful in AV installations, security monitoring centers and large public address systems where impactful, intelligible low-frequency audio matters for alerts, announcements and surveillance playback. Add the E118SW to your system for pro-grade bass response and dependable performance on every gig — order or spec it for your next install.
