QSC KW153 3-Way Active Loudspeaker

Building on the success of QSC's K Series, the KW153 represents the next evolutionary step in wood enclosure loudspeakers. QSC system engineers have created the KW153 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.


- 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 and Intrinsic Correction enhances system performance
- DMT (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
- M10 rigging points for suspended installation (full-range models)

High Output

Like K Series, the KW153 features a QSC designed, 1000 watt (2 x 500) Class D power module. And continuing in the K Series tradition, the KW153 is fitted with the identical high-output 1.75" HF device and woofers of the same high quality design.

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 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 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 our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.


The KW153 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 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.

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 KW153 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 KW153 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 with a KW M10 KIT (sold separately).

"You're gonna love this speaker!"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I just hope that this speaker lasts a long time cause I'm really impressed with everything about it. I looked at a lot of speakers before finally buying these and I'm glad that I didn't go with my first choices.
This one speaker sounds better than my two sp2's, running @ 1200 watts each and my jbl 600w sub put together!
The "Deep" feature is awesome! It also has a lot of connection options.
Ease of Use
It took less than 10 min to read the instructions and get going.
Very solid speaker. Sure, it cost about $1,400 but it looks, sounds, and feels like it too.
Simply put, you get what you pay for and this speaker is worth every penny. Quit thinking about it. Just do yourself the favor and buy it.
Manufacturer Support
Haven't dealt with them yet but I've heard great things about customer support and they have a really long warranty if you register your product, which is really easy to do on their website.
The Wow Factor
This thing looks & sounds "pro". I've had a ton of compliments about the sound and look of this speaker.
