If it’s power you’re after, then this is your sub. QSC built 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 easy access to XLR and TRS connection options on the KW181′s rear panel.
QSC built DSP right into the KW181, so you get the absolute most out of this speaker’s formidable wattage. Guardrail protection keeps the amplifier 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 very handy cast-aluminum side handles. This sub is made to make you sound great, anywhere you use it.
