Designed to accompany the speakers from the Silver series, the Subwoofer Monitor Audio Silver W12 provides powerful and controlled bass in the surrounding sound system. Monitor Audio has developed their cones using a lightweight material with surface cavity patterns. This allows the cone to provide greater rigidity with thinner density, which in turn allows for greater response and ultimately provides more accurate sound reproduction. Additionally, the W12 features a built-in microphone for automatic position correction, using digital signal processing technology for dynamic bass performance, specially tailored to its surroundings.
