Harbinger is a pro audio brand designed in the United States by Guitar Center, which distributes the line exclusively through its retail channels. The company focuses on live sound and portable PA gear aimed at gigging musicians, DJs, presenters, and small venues, with an emphasis on budget-friendly pricing and feature sets borrowed from higher-end pro audio.

The product catalog centers on powered loudspeakers and all-in-one PA packages. The VARI LIVE series powered speakers include built-in mixers, Smart Stereo pairing, and DSP voicings, while the VARI STUDIO line covers studio monitors for music production. Other ranges include the MLS portable line arrays, MUV portable PAs, LVL compact mixers, ROAD TRIP battery-powered speakers, and matching subwoofers.

Harbinger sits in the value tier of the pro audio market, competing with brands like Alto, Behringer, and Peavey on entry-level column arrays, active speakers, and small-format mixers. It is most commonly seen in house-of-worship setups, mobile DJ rigs, school and community event use, and as a first PA for bar and coffeehouse performers.

Harbinger has 23 products cataloged on Equipboard, including PA Systems, Mixers, and Speakers & Accessories.
