KH 810 - Active Studio Subwoofer
General Description

As consumer technology advances at ever faster rates, professional technology increasingly finds itself trying to keep up. An example of this is the advent of the Blu-ray and other high definition formats that have increased the audio channel count to 7.1. 

The KH 810 is an answer to these new demands by offering a new 7.1 High Definition Bass Manager™. This is compatible with all standard consumer formats from mono through to the latest
7.1 HD systems. Eight channels of analog ensures flexible interconnectivity for modern studios. Four-mode LFE-channel processing guarantees compatibility across all formats and industries. Forth-order crossovers and flexible acoustical controls allow for seamless system integration. Built-in volume control and a hardware remote control allows for centralized system control independent of the source, and the electronics can be remote located to reduce cabling

The latest amplifier technology and acoustical components have been used to ensure the most accurate sound reproduction possible. Robust drivers, a rock-solid cabinet, and carefully designed ports guarantee a tight, articulate, and distortion-free low frequency reproduction, even at high replay levels. Using the sum output, Plane Wave Bass Array™ (PWBA™) techniques acoustically improves lateral consistency in the listening area. The bass extends down to 18 Hz.

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 – Product Selection Guide.
