QSC KW152 2-Way Active Loudspeaker

Building on the success of QSC's K Series, the KW Series represents the next evolutionary step in wood enclosure loudspeakers. QSC system engineers have created the KW Series to feature all the groundbreaking electronic attributes of the popular K Series while at the same time designing a product that is both smaller and significantly lighter than previous wood enclosure models.


- K Series performance in a lightweight, birch design
- 1000 watt Class D power modules in all models (2 x 500 W)
- Extensive DSP featuring DEEP(tm) and Intrinsic Correction(tm) enhances system performance
- DMT (tm) (Directivity Matched Transition) ensures uniform coverage across the entire sound field
- Rugged, texture-painted birch enclosures
- Four-position Mic/Line gain (full-range models)
- Tour-grade 16 gauge steel grilles
- Comfortable ergonomic handles
- 35 mm pole sockets with Tilt-Direct (tm) (KW122, KW152)
- M10 rigging points for suspended installation (full-range models)
- KW122 also functions as stage monitor

High Output

Like K Series, each of the four KW Series models features a QSC designed, 1000 watt (2 x 500) 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.


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 the 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(tm) protection, first introduced on the GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.


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.


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.


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).

I'll hold on to em till some try's to steal em but they gotta get by my M-4 first. I will hand on to em for smaller gig's. But I already am getting quotes on a complete KLA system I have already put all my other gear up on consignment at a local store. I considered the JBL vertec but I am leary of the curves at the horn end of em. Looks like a wound waitin to happen. The only draw back is the fact that I can't fly em like I was hoping I could. But I have a friend who's a machinest and he's is comming by today to design and build some fly bars for em. And no I would still use QSC. Like I said I have used them all from JBL Srx. mp's to Peavey's Qw's and even tried some Mackies for around three gig's. They are built very well and i wish I could fly em on the Horz.

I am using it to replace some older JBL's MP225's that I had rewired to bi-amp. I was looking for something lighter and powered. I set them up in my garage to do a small test. I just set them right on top of my sub's two double 18's Peavey QW's with 8ooo watt's pushin em switched them to ext. sub and they kept up with no problen! I carry a DB meter to set levels when we are in a small room drove them to 124 DB and they didn't even clip. I am going to buy two more and have a fly arm built and get em up there about 12 to 14 feet.with just the mid's and highs comming through them for the money you can't beat em, PERIOD.The Buckster

They come with all you need. I really read more like the locking high voltage lines. I contacted QSC about flying them and I was told not to hang them from one another due to phase cancellation, You would have to set the lower speaker cab down @ 45degrees to keep the horns from overlapping. They said you would need to it on the vertical, which would be a pain in the a%$. I will keep em for a amall system and buy the KLA's which have a much narrower dispersion on the horns.

Ease of Use
All the manual's are straight foward and to the point I really like the disc they send with them so you can file the mess in yo puter and forget it. If you know anything about sound and can read the back of the cab. They are a breeze to set up and use. As far as what I do with em, I run a five peice classic rock band through with using 19 channels,,,everything is mic'd up. We are doing a out door festival at the end of this month we shall see how well they carry it down the street.

I have been doing this for around forty years now,,,Yup I is an ol'fart but I still ROCK. I have been around and have owned some really nice stuff over the years and would say it is built as well as anything out there. I pushed them suckers with the sub's at that level for around three hours straight if they were goin to fail I would have fried em. I couldn't even get em to clip! But again I have them in ext sub mode which according to QSC is a bi- amped Mid and high only set up. The finish is as good as the rest perhaps a little bit better the splatter paint is repairable if you ding one up. I bought the covers which are very well made. The Life? I have been running crown class d's bi amped on my monitors for around six years with a drive rack,,and knock on wood have not a crash one.

They are well worth the money like I said I am ordering two more today but I am going to add the 152's for the versatility.

Manufacturer Support
I have been using QSC's for around 25 tears they tech. guys are the best and I mean that. Most folks think crown is the one and only for pro gear. It is without a doubt very good gear But still own two of the old MX1500a's they are still my monitor rack and still gettin up just as clear as the day I bought em. The guysand girls @ QSC are very in tune witcha and can tell what what you need to know normally right the or the most I have ever had to wait on a call back was around 15 min's try gettin that from crown or any of the other companys.. As far as service honest to god truth never needed any again knock on wood man...

The Wow Factor
I don't think I would want to sleep wit em but they are are tuff looking cab's. Just pick one up and you feel how well ther're made

pro I toured in the big league back in the day
