Rate and Review This Product
Building on the success of QSC's K Series, the KW181 represents the next evolutionary step in wood enclosure loudspeakers. QSC system engineers have created the KW181 to feature all the groundbreaking electronic attributes of our popular K Series while at the same time designing a product that is both smaller and significantly lighter than previous wood enclosure models.
Features
- 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
- M10 rigging points for suspended installation (full-range models)

High Output
Like K Series, the KW181 featuress 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.
DSP
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.
Connectivity
KW181 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. 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.
Control
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(TM) 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 KW181 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 KW181 is designed to withstand the rigors of professional use. Advanced construction processes, premium-grade Baltic birch cabinetry, ergonomic, cast aluminum handles, low-noise casters 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 provides for a positive, wobble free connection to a threaded speaker pole (included).

"Good Quality, louder than anticipated."
Sound:
Best sub that I have heard yet, I set it up to do a sound test and before the sub even clipped, I was rattling the neighbor's windows over 40 feet away. Good sound, I bought 2 total, waiting for the second one to come in.
Feature:
nice plastic type coating over the wood to protect cabinet.
Ease of Use:
plug and play, powered sub
Quality:
bought it under scratch and dent, however could not find a scratch on the whole thing, lucky me. Maybe it was because the box was damaged a little bit more than usual
Value:
Good value, in my case it was a great value for scratch and dent which was $300 off what the retail price was. retail value is a little high
Manufacturer Support:
N/A have yet to contact QSC
Overall:
great product, I would buy another, and I already have. I am excited to hear the two subs together. I used to use a B-52 ACT18 powered sub 1200 watt, and this 1000 watt is 30 pounds lighter as well as louder.
Style of Music: All / Dance
