The Earth Will Move When You Fire Up This Sub!

When we first experienced QSC's super-powerful and amazingly portable active K-series PA speakers, we were blown away, to say the least. Now, here's your chance to change the way you look at live sound; add the KW181 active subwoofer to your PA rig and prepare to be amazed! QSC packed a 1,000-watt, Class D powerplant into this sub's premium birch enclosure, and completely effective built-in DSP lets you get the absolute max out of its 18" speaker. You'll love the connection and control options on the KW181's back panel. You'll also love the fact that this sub is made for the long haul. You won't believe how much beef this outstanding subwoofer adds to your sound!

If it's power you're after, then this is your sub. QSC made the KW181 to give you big-time performance, to the tune of 1,000 watts. And, thanks to the Class D design, this speaker won't break your back when it's time to set up or tear down! You get really simple access to XLR and Tip-ring-sleeve connection options on the KW181's rear panel.

QSC made DSP right into the KW181, so you get the absolute most out of this speaker's formidable wattage. Guardrail protection keeps the amp safe from overloads and minimizes clipping. Hit the DEEP switch and hear just how big this sub can get. This isn't just a series of filters and limiters thrown in to enhance the sound; this DSP makes an already outstanding speaker incredibly efficient and perfect for any room.

You know that a well-made loudspeaker is only as good as the ruggedness of its enclosure. After all, if it can't take the rigors of the road, then what good is it? That's why QSC made the KW181 extremely tough. You get premium-grade Baltic birch cabinet construction, a tough steel grille, and totally useful cast-aluminum side handles. This sub is made to make you sound amazing, anywhere you use it.
