QSC reinvents the lightweight powered PA speaker with the K12.2. DSP presets and custom settings give you full control over 2000 watts of room-filling sound.

The QSC K12.2 model is quite simply the next standard in powered loudspeakers. Each model is equipped with a 2000-watt amplifier module that combines with elegant design and advanced DSP to deliver pristine sound quality and smooth pattern control across the listening area.

The QSC K12.2 Powered Loudspeaker represents the best-in-class loudspeaker for today's demanding audio professionals. The perfect combination of elegant design, superior audio performance, high functionality, simple and intuitive operation, and genuine QSC reliability, K.2 delivers extraordinary results for users in both portable and installed applications.

Advanced Power and DSP:

The 2000 Watt power module delivers ample burst and continuous power for the loudspeaker's premium drivers. It has been designed with very low-noise fan cooling, enabling the enclosures to be used in settings where background noise must be kept to a minimum. Carefully tailored, subtle and sophisticated dynamics processing is used to protect the drivers from damage and the performance from distortion.


The user may select may select from an extensive list of factory preset EQ contours including Live, Dance, Monitor, and many more.


Savable and recallable Scenes can store information like user EQ, Delay, and input configuration settings.


A pair of balanced combo XLR/F plus 1/4" TRS connectors with independent gain control are provided. The first is equipped with selectable MIC/LINE read more (Microphone or Line) level input while the second offers selectable HI-Z/LINE (High Impedance or Line) level input, specifically for musical instruments. Both inputs are connected directly to a pair of XLR/M throughput connectors so that the signals may be "daisy-chained" to another audio device. A 3.5 mm TRS input jack with independent gain control is also provided for connection of sources such as smart phones, computers, and MP3 players.


In addition to the two throughput XLRs, a line-level output with the mixed signal from all inputs is also provided.(An optional security cover (K-LOC) may be installed to prevent unauthorized tampering of settings)


DMT (Directivity Matched Transition) design matches the coverage angle of the woofer at the cross-over frequency with the horn pattern to ensure uniform response across the coverage area. Intrinsic Correction techniques are also employed ensuring smooth power response from the loudspeaker. The result is an extremely accurate loudspeaker that behaves well in a wide range of acoustic spaces with little or no equalization.

Flexible Design:

Each model is housed in a rugged ABS enclosure with a professional yet unobtrusive appearance that is at home in any application. Each model can be utilized in either main PA or floor monitor applications, while ergonomic handles and a heavy-duty steel grille with fabric lining further enhance overall appearance and functionality. The dual pole cups allow a zero or 7.5 degree downward tilt when deployed on a pole. This allows for more even coverage across the listening area and less problems due to rear wall reflections. For suspended applications, integrated M10 fittings with a single pullback are included to accommodate M10 eyebolts. An optional yoke mount accessory is also available for permanent installation to walls and ceilings or for temporary attachment to truss (requires 3rd party hardware).

These speakers were I thought pricy but I needed to upgrade so I bought a pair. Straight out of the box I was extremely satisfied with the horsepower these puppies had set to 0 and default settings. They’re built solid and the interface is stupid simple to use for different things. From dj venues to main speakers for bands and acoustic sets to stage monitors. 10/10, I highly recommend these speakers and zZounds. Products second to none and nowhere will you find customer service like these guys. Thanks for helping the little guys have professional shows!!!

These speakers are way more than what I was expecting coming from a 12. The clarity is amazing at ANY level and I never saw the limit light even blink for a second at extremely high levels. Plays any type of music from Cajun/zydeco to hard rock flawlessly.

Ease of Use
It’s extremely easy to get great sounding music from it. Simply plug it in and you’re off. If you have any knowledge of how to use a mixer or dj controller, you won’t have any issues at all. All the “mud” I had in mics before is gone. What you hear through these speakers is about as spot on as you can get to hearing it out of the headphones on the main mixer.

These speakers are solid. Very well made and seem durable. I see them lasting for years and years as long as you take care of them and respect your equipment. Put them in your will!! read more

For the price, I THOUGHT it was steep but then I plugged them in and plugged them into my mixer and was completely satisfied with the price vs what you get. Outstanding product and I’ve seen some cost double what these are going for and not sound as good out of the box on default settings.

The Wow Factor
These speakers look and feel very professional. Not too flashy, made to blend into the background but when that blue light on the front comes on, they’re far from being missed in the landscape. 10/10, I’d definitely recommend these on looks.

Musical Background:
Dj/sound engineer for live bands

Musical Style:
Any and all of it. Whatever the crowds feeling. Go with the flow!!
