What Do We Mean by “Obsessed”? There’s a fine line between loving sound and being obsessed with it. Or so we’ve been told. Because when it comes to making things sound their absolute best, we have a hard time believing that “good enough” is good enough. Even greatness is not enough. Sound must be flawless. Perfect. Uncompromising.


Where We Started, Where We Play
Definitive Technology was founded in Maryland in 1990 by a sound obsessed veteran of the loudspeaker industry and a group of brilliant audio engineers on a mission. Quickly, we became the number one premium speaker brand in the United States. Soon, our offering expanded from a core home theater line to a full array of products designed for no-compromise sonic performance for every room and application. Over the years, the assortment has expanded to include Hi-Fi listening speakers, high performance subwoofers, architectural and built-in speakers, weatherproof outdoor sound, and most recently, streaming sound bars with HEOS Built-in.


Award-Winning Signature Sound
We earned our award-winning reputation by crafting loudspeakers of the highest performance and quality standards. These loudspeakers provide an unmatched, signature sound, renowned globally for their big, immersive sound field, ultra-wide dynamic range, crystal clear highs and thunderous bass. In short, speakers that deliver thrilling experiences to music and movie lovers like you, wherever you live, work or play.


Designed in Maryland, But Now a United Family
We still design and engineer our speakers at our original Acoustic Research and Development (ARAD) facility in Owings Mills, Maryland, but today we’re part of a larger family: Sound United. With sister brands that include Boston Acoustics, Bowers & Wilkins, Classe, Denon, Marantz and Polk Audio, our product and engineering teams span the globe and include the brightest, most passionate and inspired minds in performance and luxury audio. We share knowledge and ideas and collaborate on a vision to bring joy to the world through sound.


Our Mission, Our Promise
We don’t just want you to hear the movie—we want you to feel like you’re in it.  When you listen to music, we want you to be thrilled that your Definitive Technology speakers reveal details that you’ve never heard before—even on your thousandth listen. And when you move from room to room or even outdoors, rest assured that the Definitive Technology sound and performance you love will be right there with you. Our over three decades of dedicated fans, plus countless awards and accolades, are testament to that fact.
