In the KLA12, QSC gives you a modular line array speaker with a "Click and Play" design. KLA12s can be coupled easily to form arcuate line arrays -- connect as many boxes as you need. With just five of these boxes, you can get complete 90-degree vertical coverage to send sound evenly across a big audience. QSC KLA12 speakers are ideal in situations ranging from parks, to large halls, to houses of worship.

Modular 2-Way Powered Design

Each speaker module itself is a two-way design setup with a 12-inch low-frequency transducer and a 1.75-inch compression driver. Each KLA12 employs a super-efficient 2 x 500-watt power amp, which allows you to combine up to link up to five KLA12s and/or KLA181s (QSC's complementary 18-inch KLA subwoofer) and drive the whole array off a single 15 amp, 120 volt electrical circuit.

Easy as Possible to Assemble

The QSC KLA speakers were designed to be so easy to assemble, that you can even put an array together alone if you need to. Operators are aided in their task with the unique self-contained SOLO Rigging System that allows you to quickly assemble read more and disassemble a complete rig without the need for any special tools or hardware.

Numerous Sound Control Features

The KLA12s offer you a number of other features that make them so exceptionally friendly to use. The Ar-Q Arcuate Equalization processor onboard lets you perform line array tuning that compensates various dimensions of the tonal curve depending on the number of boxes in the array.

Select the DEEP mode (Digital Extension and Excursion Processing), and QSC's DSP algorithm provides noticeably extended bass response, while actively protecting your speakers from damaging low-frequency transients. You can also select a Flat mode, or set your KLA12s to run with external subwoofers.

QSC's proprietary Intrinsic Correction runs in the background -- performing active adjustments to time, frequency and amplitude response to achieve the flattest possible bandpass target. GuardRail circuitry protection keeps the amplifier safe from any damaging distortion.

Super-Versatile I/O Options

When you start to daisy-chain multiple KLA Series loudspeakers together, you'll use the single remote pot wired to the on-board Phoenix-style connector on the rear panel. Additional I/O includes a balanced, line-level XLR input in parallel with an XLR Thru connector, PowerCon In and Thru connectors, and Attenuation Control. Easily visible LED indicators let you monitor Signal, Limit, Power and Standby status.

Verified Customer zZounds has verified that this reviewer made a purchase from us.
Best purchase I have made by far when it comes to powered speakers. Blows away my JBL's
Sound
These sound amazing in an array of two or three units per side. They match up perfectly with the KW181's when you don't need to fly subs.
Features
The built in DSP for setting up the array size is very simple, qsc has the kla12 file setup and ready for download on the website so you can model the sound for an event beforehand. Powercon connectors make setup safe and secure.
Ease of Use
You can setup anything from a 1 to 5 cabinet array in seconds. Can fly this setup with just 1 or 2 people. DSP & Gain controls are so simple someone that has never setup the system before can do it.
Quality
Great build quality, solid construction. Best stacking/flying hardware I have seen.
Value
They are a bit expensive but for what you get well worth the price.
The Wow Factor
The look alone of a 3 speaker array will wow the audience before they even hear the amazing sound
