1000watt, 18'' Active SubWoofer - Single

The QSC KW181 represents the next evolutionary step in wood enclosure loudspeakers. QSC's system engineers created the QSC KW181 to feature all the groundbreaking electronic attributes of their popular K Series while at the same time designing a product that is both smaller and significantly lighter than previous wood enclosure models.

QSC KW181 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™ and Intrinsic Correction™ enhances system performance
• DMT™ (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

High Output
Like K Series, the QSC KW181 features a QSC designed, 1000 watt (2 x 500) Class D power module.  And continuing in the K Series tradition, the QSC KW181 is fitted with the identical high-output 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.

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

Connectivity
The QSC 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.  Separate direct outputs are also provided on each channel for additional output flexibility.

Control
The QSC KW181 also features on-board switches which provide preset EQ settings. 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 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.
