The QSC K Series is quite simply The New Standard in lightweight powered loudspeaker systems. Under the direction of Pat Quilter, QSC's team of amplifier engineers have created a new standard in Class D power modules unparalleled in the industry. Next, breaking from the traditional loudspeaker paradigm, all full-range models (K8, K10, K12) are fitted with the identical 1.75" HF device for unparalleled performance, regardless of speaker size.  Extensive DSP processing is employed throughout, providing levels of sonic clarity and total output that defy the system's size and weight. Premium-grade materials, advanced construction processes and multiple mounting and suspension options allow for a wide range of live and installed applications. 

Inputs, Outputs, Mixing and EQ
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. 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. 

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. 

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

Light and Rugged
K Series full-range models are housed in rugged yet light ABS enclosures with a professional appearance that is at home in any application. ABS is a far more robust material than conventional speaker plastics and offers an additional measure of sonic clarity due to its internal rigidity. Ergonomic aluminum handles and a highly protective steel grille complete the package for ease of transport and long term durability.

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.
The E Series is a range of passive loudspeakers intended for sound reinforcement applications including live performance, DJ and dance music, karaoke and production. With continuous power ratings from 300 to 800 watts, E Series is a great match for QSC GXD and PLD amplifiers. While E Series speakers will perform well with any professional amplifier, QSC has developed custom DSP tunings for GXD and PLD amplifiers that will produce extraordinary results
AcousticPerformance™ is a line of professional, loudspeakers, ideal for a variety of installed sound reinforcement applications requiring high power in a stylish enclosure. DMT™ (Directivity Matched Transition) in 2-way models ensures smooth, coherent power response across the listening plane

The KLA Series brings the power and sophistication of a line array system into an easy-to-use product significantly redefining the line array product category. With its simple Lift, Click and Play approach, KLA can be deployed in a fraction of the time required by comparable line array products.

This fixed arcuate, active line array system is ideal for a wide range of portable and permanently installed applications ranging from live entertainment to houses of worship or other venues where a line array system is desired. 

KLA Power Module

The KLA Series is comprised of two models, the KLA12 12-inch, 2-way loudspeaker and the KLA181 18-inch subwoofer. The KLA12 features a highly efficient 500 watt by 500 watt power amp module and the KLA181 offers the same highly efficient power amp module in a 1,000 watt configuration. This efficient design enables up to five KLA models (any combination of KLA12 and KLA181) to be driven off of a single 15 amp, 120 volt electrical circuit. 


KLA loudspeakers incorporate QSC's DEEP™ DSP algorithm - providing extended bass response by actively managing potentially damaging low-frequency transients - and GuardRail™ circuitry protection which prevents the amplifier module from unnatural and destructive clipping

As an energy saving feature, the Auto Standby mode automatically engages after five minutes of inactivity but upon resumption of audio signal, the power module on the KLA will awaken instantly for immediate output. 

In an installed application, multiple KLA Series loudspeakers can be "daisy-chained" for total gain control from a single remote pot wired to the on-board Phoenix-style connector. Additional power module characteristics on KLA include a balanced, line-level XLR input in parallel with an XLR "Thru" connector, PowerCon™ In and Thru connectors, Attenuation Control and LED indicators for Signal, Limit, Power and Standby status.

KLA181 Subwoofer

In addition to DEEP™ DSP algorithm, GuardRail™, Auto Standby, balanced line-level XLR input with an XLR "Thru" connector, Attenuation Control and LED indicators, the KLA181 subwoofer also includes a polarity switch to optimize summation between subwoofer and top-boxes.

Rigging & Deployment 

For maximum deployment flexibility, KLA loudspeakers can be either ground deployed or flown. As a ground stack, up to two KLA12 enclosures can be mounted over the KLA181 or the KW181 subwoofer via a threaded pole socket, or without a sub using an appropriately rated loudspeaker stand. 

Arrays of up to 480 lbs (218 kg) (with a maximum five KLA12 and two KLA181 enclosures) can be flown via the included M10 fittings or the optional KLA AF12 array frame.
