A passive subwoofer featuring twin 18-inch, high-excursion, direct-radiating transducers set within a bass-reflex designed housing with streamlined vents to enhance low-frequency response. This robust casing is crafted from top-quality Baltic beech and birch plywood. A resilient steel grille, paired with an acoustically transparent fabric, safeguards the front of the enclosure. Designed with user-friendliness in mind, the unit comes with six built-in handles, dual stacking runners, and corresponding top tracks for straightforward alignment. The embedded, seamless hardware facilitates easy rigging and pairing with other speakers from the same series. By coupling two or more of these units and utilizing the appropriate presets, users can achieve either omnidirectional or cardioid sound patterns. The subwoofer is optimally powered and safeguarded by a unique amplified controller via a dedicated preset.
