The VO-W woofers are PA style, high output woofers designed for enthusiasts who want sound quality and high output. By combining design elements from pro audio and high-end car audio, DD has developed a new type of ultra efficient driver aimed at delivering high levels of clean output. The VO-W woofers feature performance refinements like large diameter voice coils, high-energy motors, cast frames, and the unique ability to thread on our VO-CT compression tweeters for coaxial applications. The low moving mass design coupled with tight motor tolerance produces ultra fast transients and high output able to keep up with any subwoofer system, or you can use them as stand alone PA drives. The VO-W Woofers will transform an ordinary system into a concert level crowd pleaser.
