I ordered this to replace a speaker that, as it turned out, did not need replacing. It was listed as "Open Box" and has a "DEMO" model on the box. I haven't actually taken the speaker out, but warranty info from Sweetwater/QSC should be in the packaging. I can send it back, but that seems like more of a hassle than selling locally. I can also keep it, because I want to, but that doesn't seem responsible 🙃.
From Sweetwater: "The QSC K10.2 offers the familiar voicing, elegant style, and rugged reliability that the K Series is known for, plus double the power, increased SPL, and greater bass extension. Improved DSP management exhibits unprecedented clarity. It's also deceptively easy to use — the K10.2's factory presets cover just about any application you can think of. And if you want to tweak things yourself, there are multiple user-adjustable parameters on tap. This lightweight powerhouse is ideal for bands, DJs, and more, and its wide dispersion ensures that your entire audience experiences top-notch sound. Whether you use the QSC K10.2 in a portable or installed situation, you'll achieve superior results.”
