Depth 215 is built for the large listening room or private cinema where the lowest notes should arrive with scale and certainty. Its sculpted exterior keeps the visual language luxurious, but underneath it is a serious bass system designed for the moments when a soundtrack demands everything.
Dual BalancedForce woofers each receive their own high-power Dynamic Peak Class-D amplifier, creating high-power of peak power and high-power RMS in total. The twin-driver architecture and heavily reinforced cabinet give this subwoofer immense output without sacrificing control.
ARC Genesis calibration is supported by the included microphone, adjustable stand and cables, helping the Depth 215 integrate smoothly into the actual room. It is a statement choice for high-end two-channel systems and large-scale home cinema.
