    QSC KW181 Powered Subwoofer (1000 Watts, 1x18") 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.
