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

        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!

                    If you are looking for a really powerful sub with lots of options, this is the one for you. The KW 181 has an unforgiving 1000w of internal power, guaranteed to shake whatever room you are playing in. The 18" speaker is more than enough to deliver strong punch from kick drums and the deep sustain required for a lot of EDM/hip hop/bass heavy music. With 2 balanced outs, daisy chaining subs or linking into main speakers is simple with just some mic cables. Its intelligent electronics allow it to adjust its performance based on what is being played, giving it a consistent and reliable sound every time you use it. It also has some rolloff options and even a polarity switcher, making it useful in any application you could need it for. And the internal fan helps regulate the temperature, ensuring that it will not overheat, and also helping to prolong the life of the unit as a whole.

                        These KW181's deliver absolutely bone-crunching low end. Our band is drum and bass guitar driven, and we love these things. Of course, we have slightly EQ'd them to really get what we want out of the kick drum and bass guitar and have added HPF on most of the other instruments/vocals to clean up our mix. But expect to be punched in the chest. Lot's of power! Get one...or two!

                        qsc has always made great speakers. The Kw-181 is no exception. Wall shattering bass.

                        Built in casters definitely make it much easier to move. Dual xlr I/O makes it easy to take this from a 2.1 system to a 2.2.

                        It's definitely got some weight to it but for the amount of volume this sub puts out you can deal.
