About This Product

QSC K12 K Series 2-way 1000 Watt Active Speaker with 12” Woofer

The QSC K12 is a 12" 2-way PA speaker system boasting a 1,000W Class D power module and ~75° horizontal and vertical coverage. Low frequencies extend to ~48Hz (-10dB high acoustic output, 131 dB peak). This low-frequency extension makes the QSC K12 an ideal choice for music playback and live reinforcement of instruments, especially in venues where more directional speakers are needed. Equally at home in the role of stage monitor, the QSC K12 speaker enclosure has an angled side for use as a low-profile, horizontal wedge and a flat side for proper side-fill use.

QSC's K12 PA Speaker features a 1-3/4" HF device in its 2-way enclosure. The primary differentiator in K Series speakers is the resulting output dispersion—the K8 being the widest at 105° and the K12 the narrowest at 75°. This radical approach is achievable due to a process called Directivity Matched Transition (DMT). DMT allows QSC to take advantage of a fundamental law of acoustics: smaller diameter woofers have wider coverage patterns than larger ones. The K Series matches the HF device to the LF dispersion, allowing for the smoothest and flattest frequency response possible across the entire sound field.

Add to this advanced DSP processing and an enclosure molded from ABS—a material far more rugged and sonically pleasing than conventional plastics—and the QSC K12 delivers exceptional performance in this category of loudspeakers.

Several proprietary QSC DSP technologies are incorporated into the K Series. One such technology is Digital Extension and Excursion Processing (DEEP). DEEP allows each of the K Series models to deliver levels of low-frequency extension previously impossible in enclosures of this size. Intrinsic Correction, first featured in QSC line-array technology, use dozens of spatially averaged measurements mapped to the processor to deliver smooth and accurate reproduction across the entire sound field.

Preventing amplifier clipping or overload is QSC's proprietary GuardRail technology. GuardRail closely monitors the input voltage and controls the amplifier output stage before the onset of clipping. Unlike typical clip limiters, when GuardRail is activated, the results are all but undetectable—there's none of the typical "pumping" associated with other methods. In addition, user EQ controls are provided to select between subwoofer settings (EXTSUB, VOCAL, or FLAT response).

The K12 speaker boasts other user-friendly features. For example, when the speaker is pole-mounted, the Tilt-Direct pole socket converts to a 7.5° down-tilt with a simple 180° rotation of the dial. A locking IEC power cord is included, preventing accidental disconnect during a performance. For installed applications, connecting a commonly available potentiometer to the unit's Euroblock connector allows the operator to have gain control from a remote location. Multiple K Series units can be daisy-chained together to one centralized control. Additionally, the K Series enters Standby mode after 5 minutes of inactivity, conserving power.

The entire QSC K12 package is housed in rugged and sonically friendly ABS (the sub in birch plywood) with steel grilles and easy-carry ergonomic aluminum handles.

Processing, Connectivity & Monitoring

The brain of the system is its expansive digital signal processing. While the DSP functions are optimized using Intrinsic Correction, DEEP, DMT, and GuardRail technologies (with the high-pass filter included for use with subwoofer systems), two XLR-combi inputs, each with its own Level control, are provided. Both accommodate line-level inputs and one may be switched to microphone level sensitivity. Phono (RCA) input jacks are also included for connection of consumer electronics sources. Dual XLR outputs are provided for dual "loop-thru" XLR/M connectors and a single XLR jack is available as a summed output. All 3 input sources may be used at once and mixed via the 2 Gain control knobs.

Input Panel LED indicators are provided for Power, Signal Present, Mic Level Sensitivity, and Limit annunciation. A front-mounted power LED may be disabled by means of a rear-panel switch when desired or set so it indicates when the limit circuitry has been engaged.

Waveguide

Each K model incorporates a conical waveguide that maintains pattern control all the way down to the crossover frequency. The coverage angles of the waveguides are tailored for a smooth transition from woofer to compression driver with far less "waistbanding" or other directivity related anomalies than other products in this class.

Suspension and Mounting

The K12 2-way PA speaker may be pole-mounted, suspended, or yoke-mounted. The K12 yoke accessory kit (not included) allows for either horizontal or vertical yoke mounting, providing a flexible means of attaching K Series loudspeakers to a building structure or truss. When suspended deployment is required, M10 threaded inserts support vertical or horizontal suspension, while the integral polemount socket accommodates 35mm speaker poles for use on a speaker stand or over a sub. The pole socket is designed so that the speaker may be angled down 7.5° in order to cover the audience while keeping acoustic energy off reflective walls and ceilings.

K12 Features:

  • 12” Woofer; 1.75” diaphragm compression driver.
  • 75° Nominal coverage angle.
  • Maximum SPL 131 dB peak.
  • 1000-watt continuous Class D power modules in all models.
  • 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 enhances system performance.
    • DMT (Directivity Matched Transition) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.
    • 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 band pass 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 protects both the amplifier module and your performance from unnatural and destructive clipping.
  • Attractive and professional appearance.
  • Rugged ABS enclosures.
  • Functions as a monitor wedge.
  • 16-gauge powder coated steel grille.
  • Comfortable ergonomic handles.
  • 35 mm pole sockets with Tilt-Direct.
  • M10 rigging points.
  • Eyebolt and yoke mount accessories available.

 


QSC KW181 1000 Watt 18” Powered Subwoofer

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:

  • 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).

KW181 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 (35 mm diameter, 36 inches (91 cm) long, M20 thread.).
  • Comfortable ergonomic handles.
