The Ferguson Hill bass system is designed to acoustically and visually match the FH001 Loudspeakers, giving a seamless integration between the sub woofers and the horn speakers. The FH002 Bass Units come as a pair of clear acrylic spheres, with 300mm drive units and a distributed port loading. The Bass Amplifier enclosure is mirror-polished stainless steel, fully damped and its frequency response is set to complement the FH001 Loudspeaker.
