This 3000 W powerhouse is a high-performance 21\"\" bass reflex subwoofer that delivers deep, precise, and powerful bass foundation − ideal for mobile DJs, clubs, live events, festivals, and permanent installations.\u003cbr\u003e\r\n\u003cbr\u003e \r\nThe centerpiece of the ICOA® PRO SUB 21 A is its extremely powerful 21\"\" woofer with a 4.5\"\" neodymium motor. Thanks to its long-excursion design and finely tuned suspension, this subwoofer delivers an unexpectedly tight, dry, and precise deep bass.\u003cbr\u003e\r\n\u003cbr\u003e\r\nThe powerful Class-D amplifier delivers up to 1500 W RMS (3000 W peak) and 136 dB max. SPL, providing ample headroom and reliable deep bass performance. Four extra-large, airflow-optimised bass reflex ports ensure a rich low-end down to 29 Hz.\u003cbr\u003e\r\n\u003cbr\u003e\r\nThe modern SysCore® DSP with FIR\/IIR filters and advanced limiters ensures distortion-free sound and safe operation, even at extreme volume levels.\u003cbr\u003e\r\n\u003cbr\u003e\r\nTwo XLR inputs, two XLR outputs, and a powerCON loop-thru connection allow for effortless system cabling and flexible expansion.\u003cbr\u003e\r\n\u003cbr\u003e\r\nWith a 4-band PEQ, delay function (up to 50 m), and three selectable crossover frequencies (80 Hz, 100 Hz, and 120 Hz), the subwoofer can be flexibly adapted to different setups. Pre-configured presets for low-latency monitoring and cardioid applications simplify the setup.\u003cbr\u003e\r\n\u003cbr\u003e\r\nAll settings can be controlled intuitively via the colour display with One-Knob control or through the free \"\"ICOA PRO\"\" app. The app enables quick and wireless adjustments and allows you to connect multiple loudspeakers. A stereo setup with up to two tops and four subs, including direct music streaming via Bluetooth 5.1 and TWS, can be configured and set up in the app within seconds. A status LED on the front of the subwoofer simplifies identification and provides feedback on the limiter’s operation when needed.\u003cbr\u003e\r\n\u003cbr\u003e\r\nThanks to integrated stacking recesses and two M20 pole mounts, the subwoofer can be securely stacked horizontally or vertically for maximum flexibility.\u003cbr\u003e\r\n\u003cbr\u003e\r\nThe 15−18 mm birch plywood enclosure is deliberately compact, with dimensions comparable to traditional 18\"\" models. At just 562 mm wide, it fits perfectly into common transport vehicles (Mercedes Sprinter, Fiat Ducato, Ford Transit, and VW Crafter), even as part of standard transport setups such as Sprinter-Case\/TRANSflex next to a subwoofer.\u003cbr\u003e\r\n\u003cbr\u003e\r\nThis space-saving design, combined with a durable polyurea coating, makes the ICOA® PRO SUB 21 A the perfect choice for touring and installation applications.\u003cbr\u003e\r\n\u003cbr\u003e\r\nEight ergonomic handles ensure optimal grip from all sides, simplifying setup and teardown.
