DBA Resonator Speakers is designed with an all-metallic enclosure using a full-range speaker and a down-fire woofer. Apart from the metallic enclosure, the front-facing "Resonance Disc" is a revolutionary and patent-pending design; this allows the innate timbre to be more audible by means of vibration of the signal source from the top full-range driver. As a result, the 'sustain' or the 'decay' of the sound wave are prolonged, and this can be specially tested when high-frequency samples such as Tibetan singing bowl or Hand drums are tested. Simply put, this is an unprecedented feature in speaker design. This is also a high-end active speaker designed for home, studio or lounge.
