Don't Forget

Versatile 12" 2-way active loudspeaker with 1000W Class D power module, zDSP, and much more.

Building on the success of QSC's K Series, the 2-way KW122, like the rest of the KW Series, represents QSC's next evolutionary step in wood enclosure loudspeakers. The system engineers created the KW Series to feature all the groundbreaking electronic attributes of QSC's 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 it's K series predecessors, the QSC KW122 features a QSC designed, 1000W (2 x 500) Class D power module. It is also fitted with the identical high-output 1.75" HF device and 12" cone transducer of the same high-quality design.

Defined Coverage Area
The QSC KW122 speaker also comes with Directivity Matched Transition (DMT) technology which provides matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.

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 QSC's high-end line array products, it 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 an active 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

The QSC KW122 loudspeaker, like all the KW Series speakers, features a four-position mic / line gain switch that lets you connect to 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 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. The QSC speaker also provides separate direct outputs on each channel for additional output flexibility.

Onboard switches provide preset EQ settings. The HF setting 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 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.

The QSC KW122 active speaker features 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 onboard Phoenix-Style connector. In an installed application, multiple QSC 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:
The QSC KW122 speaker, like all its KW Series brethren, is designed to withstand the rigors of professional use. Advanced construction processes, premium-grade Baltic birch cabinetry, ergonomic, cast aluminum handles, and a highly protective steel grille provide for ease of transport and long-term durability. Integrated M10 suspension points allow for flown applications.

    Awesome compact PA system

    By Heavy drinker-qBgDo

    from Portland, OR

    See all my reviews

    Comments about QSC KW122 Powered Speaker 12" 2-way 1000w:

    Absolutely happy with this investment for all the reasons above.
    Full birch plywood construction, active cooling (themostatically controlled fan for power section), limiter, top/full-range/DEEP, and flat/vocal EQ switches, flexible connection options. One thing you see in QSC's active speakers, as well as most of those from other manufacturers, is the absurd practice of using (in this case) a 2x500W power section. There must be manufacturing/budget reasons for doing this, but the fact is the tweeter can't possibly use more than 50W, so that second 500W -- which probably impresses some potential buyers -- is largely wasted since the signal must be severely attenuated to prevent destroying the tweeter. But it lets the marketing folks and the resellers boast that it has a "1,000-watt power section!" Whatever.
    The sound is extremely clear, the dispersion is good, and the cab is plenty loud for small rooms, and for big rooms with a sub. Flawless, rock-solid construction and performance. No rattles, no flaws in the spray-on finish, grille is perfectly shaped and attached. As I've read in other reviews, the switches on the back don't have the same solid feel and sure detents that one might expect, but I have no reason to think they're in any danger of failure. I'm impressed by the DEEP circuit; when you engage it, it doesn't just get loud suddenly, but seems to ramp up the sustain and harmonics of low notes to give a satisfying, full sound. I haven't run these without a sub (yet), but it seems that, in a small room, you could without missing much.
    I was happy to pay extra for this MIA product for a number of reasons. You pay a premium for its wood construction and country of origin, but because of its rock-solid construction, circuit and driver protection features and QSC's industry-best warranty, you know it's a unit that will provide years, if not decades, of service. I wouldn't dream of using these for stage monitors -- too expensive -- but I'm kicking around the idea of investing in at least one K12 that could be used as a wedge and a backup in case a KW121 ever fails at a gig (not that I think it will, but I like to have backups for *everything* because stuff happens, and if the power section fails, the cab is useless).

    Unbelievable sound

    By Michael Bills

    from South Carolina

    Comments about QSC KW122 Powered Speaker 12" 2-way 1000w:

    There are three letters to live by as a DJ.

    If you are a DJ or have a band, the QSC KW 122 speakers are an upgrade to a more professional sound. To put the Mackie SRM 450v2 and QSC KW 122's side by side would be like comparing apples and oranges.

    The sound quality from a wood cabinet speaker
    The birch wood cabinets on these speakers provide an incredible sound.
    These are pricy speakers, but with a 6 year warranty from QSC, how can you go wrong?

      When I heard one of these side by side with my Mackie Thump, I had to have it. Awesome sound, cuts right through....no more asking for "more me".
