Pump up the volume and rattle them bones with QSC’s 1,000 watt, 18” Active Subwoofer!

The QSC KW181 Subwoofer is a room shaker that will add some serious bottom end to any audio system but it’s engineered to perfectly complement QSC’s KW Series of active loudspeakers.

The KW181 boasts a 1,000 watt, Class-D power amplifier that drives a QSC 18" cone transducer to produce an SPL rating of 135 dB, only slightly lower in sound output than a jet on takeoff. And just as impressive is QSC’s proprietary “Intrinsic Correction” DSP, first featured in their high-end line array products with spatially averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat bandpass target. The result is a speaker that behaves equally well across the entire sound field.

All KW Series features a four-position mic/line gain switch that allows for connection of a wide variety of devices, plus the KW181 also offers variable output level adjustment and polarity phase switch, along with combo XLR and 1/4" TRS inputs that accept both mic and line level inputs and dual balanced male XLR full range line level outputs. Other features include a threaded pole socket and a 3 foot, 33 mm diameter  speaker mounting pole.

Premium-grade materials
KW Series is designed to withstand the rigors of professional use. Advanced construction processes, premium-grade Baltic birch cabinetry, ergonomic, cast aluminum handles, low-noise casters (KW181) and a highly protective steel grille provide for ease of transport and long term durability. Integrated M10 suspension points allow for flown applications with a KW M10 KIT (sold separately) and a threaded pole receptacle (KW181) provides for a positive, wobble free connection to a threaded speaker pole (included).

Features:
  • 18” subwoofer
  • Maximum SPL 135 dB peak
  • 1000 watt Class D continuous power
  • Extensive DSP featuring DEEP and Intrinsic Correction enhances system performance
  • Rugged, texture-painted birch enclosure
  • Tour-grade 16 gauge steel grilles
  • Threaded pole socket
  • Speaker mounting pole included (36" w/M20 thread)
  • Comfortable ergonomic handles

      Comments about Qsc 1000 Watt 18 Inch Active Subwoofer:

      All I can say is that this sub is amazing. The built in power amp is quiet and puts out all the wattage you need to make this 18 inch woofer roar. Pair this with some matching QSC powered monitors, and you have a PA rig that you can take on tour, use at practice, or for shows of any size.

            A wonderful high out put speaker with 100 watts of power and a class D power module. With this speaker, clarity of sound is a given and the sound is crisp and full. Only set back is the size, but it is more than worth it for the sound quality!

                If you need a subwoofer to constantly preform as hard as you do look no further! This thing is what you need in your arsenal that you can pull out and wreck the place! Boasting 1000 watts this is no feather weight contender, it is a BEAST! Easy to dial your EQ in for any room or situation. Very versatile it doesn't have to be a wrecking ball all the time, and not to mention very user friendly interface along side that great QSC sound!
