    Building on the success of our K Series, the KW Series represents the next evolutionary step in wood enclosure loudspeakers. QSC's 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.

    High Output: Like K Series, each of the four KW Series models features a QSC designed, 1000 watt (2 x 500) Class D power module.

    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.

    Connectivity: KW Series features a four-position mic / line gain switch that allows for connection of a wide variety of devices.  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.

    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, and a highly protective steel grille provide for ease of transport and long term durability. Wobble free connection to a threaded speaker pole (included).

    Simply the best
    What is your opinion of this product?
    I got the chance to listen to a lot of sub-woofers out loud at a store that sells them and this sub-woofer has the cleanest bass. Some subs may bang harder and louder, but this one is simply clean. Clean sound is what I was interested in and this one performed very well.

    This is a beast!
    What is your opinion of this product?
    I bought a pair of these subs about 3 years ago and to be honest, I don't think any competitors can beat the sound and built quality. No matter how much you push this thing I never had the limit light go off.

    Awesome Power Sub
    What is your opinion of this product?
    This is an excellent power sub for mobile DJ's and small bands. Very portable, can fit in mini van or suv. I bought it as a open box. The only drawback is that I did not get the poles and power cable. I had to call when my speakers arrived and the customer service guy took care of it right away.

    Thanks to AMS I was able to upgrade my gear; Loving the new QSC KW-181!
    What is your opinion of this product?
    As an upgrade or an add on, this powered sub is clean and precise with plenty of power. The construction is solid and functional (built in casters), and comes with a threaded pole for a PA mount. You get what you pay for, so if you like problems, and poor quality, this product is not for you. On the other hand if you like performance and quality, and backed by a solid warranty, then this is the Sub that will get you to the next level. Cant wait to get another one!!! Thanks AMS!
