1000 Watts of Power in a Next-Gen Lightweight Design.

High Output: Like K Series, each of the four KW Series models features a QSC designed, 1000 watt (2 x 500) Class D power module. And continuing in the K Series tradition, every model is fitted with the identical high-output 1.75" HF device (full-range models) and woofers of the same high quality design, regardless of speaker size.

Defined Coverage Area: Directivity Matched Transition (DMT™) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.

DSP: Extensive signal processing is employed throughout, providing levels of sonic clarity and total output that defy all expectations for a product in this category:

Intrinsic Correction, first featured in our high-end line array products maps 65-75 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.

DEEP and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.

GuardRail protection, first introduced on our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.

Connectivity: KW Series features a four-position mic / line gain switch that allows for connection of a wide variety of devices. Combo XLR and 1/4" TRS inputs accept both mic and line level input while a set of RCA phono inputs (except KW181) allow additional connectivity to portable MP3 players, CD players and line-level mixers. Up to three audio sources can be mixed internally and summed to a balanced output for "daisy-chaining" of multiple units. Separate direct outputs are also provided on each channel for additional output flexibility.

Control: On-board switches provide preset EQ settings. The HF setting (full-range models) can be set to VOCAL BOOST for additional presence in the critical mid-frequency area or FLAT for accurate reproduction of the incoming signal. The LF switch can be set to NORM, DEEP for additional bass extension, or EXT SUB (full-range models) for use with an external subwoofer. The rear panel LED switch can be set to POWER, illuminating the front-mounted LED when the unit is powered on, OFF for applications where it is not desirable to illuminate the front LED, or LIMIT which indicates to the system operator that the clip limiter circuit has been engaged during operation.

Tilt-Direct: The KW122 and KW152 feature a unique Tilt-Direct pole cup mounting system. A simple turn of the dial engages a 7.5 degree downward tilt of the speaker allowing acoustic energy to be kept on the audience and off reflective surfaces for applications where maximum coverage from a high-positioned speaker is desired.

Remote Gain: Remote gain control capability is offered via a potentiometer (not included) connected to the on-board Phoenix-Style connector. In an installed application, multiple KW Series speakers can be "daisy-chained" for total gain control from a single remote pot. Auto-standby mode is engaged after 5 minutes of inactivity.

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).

  • Powered Sub Woofer
Other Features Lightweight birch construction for durability and superior sonic performance

              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!

                Comments about QSC KW181 1000 Watt 18" Active Subwoofer:

                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.
