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

    Comments about QSC 1000 Watt 18 Inch Active Subwoofer:

    Enuff said...I have been studying and testing this cabinet QSC KW181 against the JBL 18XLF and I really like the 30hz frequency of the JBL (QSC only goes down to 35hz) So I could hear the difference...The problem is that [even though I love JBL] JBL is loosing the level of quality...There are so many complaints about the JBL 18XLF breaking down and having problems with it...SO I went to the ultimate test!!!! I went to the place where Madonna, Elton John, Alicia Keys and every star goes for their massive rental equipment...I checked on their website in LA[they have rental warehouses in NY, Miami, Tennesee, LA, San Francisco & Phoenix] I have rented smaller stuff from them and guess WHAT! In their personal PA System powered subwoofer section [NOT IN THE PRO-AUDIO $5,000,000 sound system section] they chose to ONLY carry one powered speaker and that is the QSC KW181....THAT TELLS ME A LOT!!!! THEY DONT LIKE TO MESS WITH STUFF THAT BREAKS DOWN EASILY!!!!

    We use these for FOH sound for live performances. Use them inside and outside. The sound is incredible. Use these along with the KW153's, you will be amazed at the sound quality. Try them you will not be disappointed.

    Comments about QSC 1000 Watt 18 Inch Active Subwoofer:

    I purchased a pair of these to go along with my pair of KW 153's. The KW 153's can handle most medium to small venues with just one pair. I debated on getting another pair of the KW 153's but I decided to go with the KW 181's.... These subs put out some great sound! I have talked to multiple retail stores about going with some JBL subs, but I keep getting referred back to QSC. I love QSC, though the JBL's seemed to catch my eye. I am very happy with these subs and would recommend them to everyone.
