The Monitor Audio Cinergy Sub15 is an ultra-high-performance powered subwoofer designed for luxury cinema installations. It can be installed in-wall, stacked, or used as a floorstanding unit, and is dimensioned to align perfectly with the Cinergy 300 speakers for seamless integration. Featuring a 1 × 15″ ultra-high excursion C‑CAM driver, it delivers deep, room-shaking bass down to 17 Hz (–6 dB) when paired with Monitor Audio’s IA750‑2 or IA750‑4 installation amplifier. Isolation feet and securing brackets eliminate unwanted vibrations and enable hidden sound-wall configurations.
