Product Description

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 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.

Features:

- K Series performance in a lightweight, birch design
- 1000 watt Class D power modules (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
- Tour-grade 16 gauge steel grilles
- Comfortable ergonomic handles

Sophisticated DSP: A Smarter Sub

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

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).

Connections and Control

On the rear of the KW181 sub, combo XLR and 1/4" TRS inputs accept line-level input. The DEEP switch can be set to NORM or DEEP(tm) for additional bass extension. 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 Control Ready

Remote gain control capability is offered via a potentiometer (not included) connected to the onboard 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. zZounds is an authorized dealer of QSC products.

zZounds has verified that this customer bought this product from us. "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
