| QSC KW181 Active Subwoofer |
w/ KW181 Cover, Whirlwind EMC-20' Mic Cable, & MiTee 25' Power Cord
Building on the success of our K Series, the KW Series represents the next evolutionary step in wood enclosure loudspeakers. Our system engineers have created the KW Series 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 design1000 watt Class D power modules in all models (2 x 500 W continuous)Extensive DSP featuring DEEP™ and Intrinsic Correction™ enhances system performanceDMT™ (Directivity Matched Transition) ensures uniform coverage across the entire sound fieldRugged, texture-painted birch enclosuresFour-position Mic/Line gain (full-range models)Tour-grade 16 gauge steel grillesComfortable ergonomic handles35 mm pole
M10 rigging points for suspended installation (full-range models)High Output: Like K Series, each of the four KW Series models features a QSC designed, 1000 watt (2 x 500 W continuous) 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™ protection, first introduced on our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.Connectivity: KW Series 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: An on-board switch provides preset LF settings. The LF switch can be set to NORMAL or DEEP™ for additional bass extension. The polarity can be set to NORMAL or REVERSE. 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.
Premium-grade materials: KW Series is designed to withstand the rigors of professional use. Advanced construction processes, premium-grade Baltic birch cabinetry, ergonomic, cast aluminum handles, low-noise casters (KW181) 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 (KW181) provides for a positive, wobble free connection to a threaded speaker pole (included).
QSC KW181 Soft CoverProtect your investment with these soft, padded covers from QSC. Construction consists of weather resistant, heavy-duty Nylon/Cordura® material. Velcro side flaps allow easy access to the speaker handles. A wide lower strap wraps around between the casters, helping secure the cover to the sub. This also protects the control panel from dust and damage. The flap on the top edge of the cover creates a perfect pouch to hold the speaker mounting pole that came with your subwoofer.MI Tee PC-16/25 Power Cord16 Gauge, 25 ft - UL Listed, Heavy Duty AC Power Cord
