Revel is an American high-end loudspeaker manufacturer founded in 1996 as part of Harman International's Harman Specialty Group, drawing on the company's research and engineering resources to pursue a scientifically-oriented approach to speaker design. The brand is known for extensive anechoic chamber testing, double-blind listener evaluations, and proprietary driver technology including beryllium tweeters, Acoustic Lens Waveguides, and Micro Ceramic Composite cone materials.

The Revel catalog is organized around several loudspeaker lines positioned at different price points, including the flagship PerformaBe series, the Performa3 and Performa4 series, the more affordable Concerta2 line, and architectural in-wall and in-ceiling models alongside Extreme Climate outdoor speakers. Product categories span floorstanding towers, bookshelf monitors, center channels, surround speakers, and powered subwoofers for both stereo and home theater applications.

Though primarily positioned in the audiophile and luxury home theater market rather than professional audio, Revel sits alongside sister Harman brands such as JBL, Mark Levinson, Lexicon, and Harman Kardon, and its engineering work is often associated with researcher Dr. Floyd Toole's influential studies on loudspeaker measurement and listener preference.

Revel has 29 products cataloged on Equipboard, including Surround Sound Speakers, Floor-standing Speakers, and Bookshelf Speakers.
