QSC KW152 KW Series15" 2-Way Multipurpose Active Loudspeakers

 

Building on the success of our K Series, the KW Series represents the next evolutionary step in wood enclosure loudspeakers. Our system engineers have created the KW Series to feature all the groundbreaking electronic attributes of our popular K Series while at the same time designing a product that is both smaller and significantly lighter than previous wood enclosure models.

High Output
Like K Series, each of the four KW Series models features a QSC designed, 1000 watt (2 x 500 W continuous) 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).

Features
  • 15” Woofer; 1.75” diaphragm compression driver
  • 60° conical DMT coverage
  • Maximum SPL 133 dB peak
  • 1000 watt Class D power modules in all models (2 x 500 W continuous)
  • Onboard mixer with two combo XLR and ¼” inputs, and stereo RCA inputs, (three audio input sources); two direct channel outputs and single summed balanced output
  • Extensive DSP featuring DEEP™ and Intrinsic Correction™ enhances system performance
  • DMT™ (Directivity Matched Transition) ensures uniform coverage across the entire sound field
  • Rugged, texture-painted birch enclosures
  • Four-position Mic/Line gain (full-range models)
  • Tour-grade 16 gauge steel grilles
  • Comfortable ergonomic handles
  • 35 mm pole sockets with Tilt-Direct™
  • M10 rigging points for suspended installation
  • Inputs, Outputs and Mixing
    Combo XLR and 1/4" TRS inputs accept both mic- and line-level input while a set of RCA phono inputs (except KSub) allow additional connectivity to portable MP3 players, CD players and line-level mixers. As many as 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. 
  • DEEP™
    Sophisticated digital signal processing provides greater low-frequency extension while precisely protecting the woofer from over-excursion. 
  • DMT
    Directivity Matched Transition matches the HF coverage angle to the natural coverage angle of the woofer for uniform frequency response over the entire coverage area. 
  • Axisymmetric Wave Guide
    The axisymmetric wave guide eliminates the phase distortions of typical asymmetric horns for more natural reproduction. 
  • 1000 Watts
    The same state-of-the-art, light-weight Class D amplifier module powers all the K and KW Series models.
  • EQ Modes
    Optimize for a specific application with the simple flip of a switch. 
  • Energy Management
    Automatic standby mode conserves energy and extends the life of the loudspeaker. 
  • LED Operation
    Switch selectable: On (power indicator) / off (dark) / limit (limiter indication) 
  • Remote Control
    Easy-to-use remote gain control is ideal for installed applications. 
  • Pro Appearance
    Sleek lines and a full grille for a more professional look than other molded loudspeakers. 
  • Locking IEC Power Cable
    Help prevent unexpected interruptions. 
  • Connectivity
    Mic/line and RCA inputs along with onboard mixing controls allow greater flexibility. 
  • Tilt-Direct™ Pole Mount
    A simple turn of the dial is all it takes to alter the vertical directivity by 7.5 degrees. 
  • Suspension and Mounting
    With integrated threaded inserts, KW Series is equally at home in mounted or flown applications. 
  • Threaded Pole
    The KW181 subwoofer comes with a threaded pole for a snug, safe fit.
  • Intrinsic Correction
    An exclusive QSC process that applies extensive acoustic measurements to noticeably improve audio quality. 
  • Class D
    Higher efficiency produces less heat and more sonic performance with lower overall current draw. 
  • Protections
    QSC's Guardrail™ technology protect your loudspeakers from overexcursion. On-demand cooling fan and thermal limiting prevent overheated electronics.
