Compact passive subwoofer boasting a high-movement, direct-emission 15-inch transducer set in a bass-reflex cabinet enhanced by streamlined vents, optimizing low-frequency output. This enclosure is meticulously crafted from top-grade Baltic beech and birch plywood. A resilient coated steel grill, paired with a sound-permeable fabric, shields the transducer. Designed for user convenience, the cabinet features dual ergonomic handles and a 35mm pole-mount socket. Additionally, twin coupling bars enable seamless integration with other compatible speakers. Specialized rigging tools facilitate both aerial and grounded setups. When paired with the right presets, linking two or more units can produce either omnidirectional or cardioid sound dispersion. For optimal performance and safety, it's specifically designed to be powered exclusively by a dedicated amplified controller using a particular preset.
