About the QSC E18SW

A beautiful sound

I remember the first time I heard a QSC powered speaker in a club. I was astonished at the quality of the sound emanating from such a compact enclosure. Now QSC offers this kind of sonic firepower with their E Series passive PA speakers. Their E18SW subwoofer features a heavy-duty 18" woofer in a compact plywood enclosure coated with black textured paint. The E18SW handles up to 800 watts RMS, delivering powerful, accurate bass that belies its relatively small size.

Pair it with a QSC

QSC designed the E18SW to work well with any mixer or amplifier, but its performance is greatly enhanced when you pair it up with a QSC GXD or PLD Series power amp or with their TouchMix digital mixer. The built-in signal processing in those products optimizes this subwoofer for live sound, floor monitor, karaoke, or DJ applications.

Two angles

The E18SW features a standard pole-mount socket that allows you to mount a full-range speaker, and a speaker pole is included. The metal grille protects the drivers from damage on the gig or in the van. QSC knows that you go to a lot of trouble to play live gigs. They've designed a sub that brings your performance to your audience without compromise.

Features

18" Passive Sub: The E18SW is a high-performance passive subwoofer with a 18" woofer (4-ohm) that features a 4" voice coil and aluminum frame. It can handle up to 800 watts RMS/3200 watts peak.

Rugged Enclosure: The E18SW features a rectangular plywood enclosure with a rugged tour-grade textured black paint. There is a perforated, powder-coated steel grille with foam lining to protect the enclosed drivers (the grilled can be removed by removing twelve screws). There are four side-mounted top-mounted handles to help carry the speaker around to performances. There are also provision for optional casters.

Speaker Terminals: The QSC E18SW is outfitted with NL4 and barrier-strip connections to connect speaker wire (sold separately). There are two NL4 terminals, one is for input and the other can be used to pass a full-range audio signal to another passive loudspeaker or passive subwoofer (sold separately) in your system.

Recommended Amplifiers & Mixers: When used with QSC's GXD amplifiers or with QSC's TouchMix digital mixers, the E Series subwoofer can also take advantage of advanced DSP (digital signal processing). QSC has developed E Series DSP settings for all three platforms. These settings support a variety of applications including live sound reinforcement (with and without subwoofers), stage monitoring, dance music, and karaoke. 

Threaded Pole: The 24" long x 35mm diameter pole provided with the E18SW threads into the M20 insert on the top of the subwoofer. The pole can support a single E10, E12, or E15 loudspeaker (sold separately) in either the straight or tilt-down position.
