Neumann KH 810 G - Active Studio Subwoofer

The KH 810 subwoofer is designed to complement our extensive range of monitors, and can be used on its own, or daisy-chained to make larger systems capable of higher SPL. The KH 810 can be used in music, broadcast, and post production studios for tracking, mixing, and mastering. The cabinet can be positioned next to a wall or flush mounted into a wall due to the front mounted port, and can be mixed freely in multichannel systems with other loudspeakers from our range
