Five Decades Of American Loudspeaker Engineering
DB+ Series Subwoofers benefits from decades of Polk’s premium loudspeaker engineering experience and were designed at our original Acoustic Research and Development facility in Owings Mills, Maryland. Our goal since 1972 has been to build great speakers that not only play loud, but also play crystal clear sound with effortless bass. The result of this 50-year engineering heritage is best-in-class subwoofers backed by numerous awards, patents, and fans like you.
We’ve achieved this by constant innovation and by leaving nothing to chance. Accessibly priced, built to exceed our patented quality-testing process, and designed to provide Polk’s legendary effortless bass, DB+ Series Subwoofers fulfill the Polk promise of great sound for all.
