OLD LYME, CONNECTICUT - APRIL 2008: Since 1967, Klein + Hummel’s active studio monitors have developed a reputation for their pioneering engineering techniques and low distortion reproduction. Now that modern production facilities require high-quality monitoring systems that can accurately reproduce anything up to the latest 7.1 discrete high-definition formats, Klein + Hummel has developed the O 810 and O 870 subwoofers to surpass these new demands.

The O 810 and O 870 subwoofers, which make their debut at the 2008 NAB Show(tm), each are the perfect compliment to Klein + Hummel’s increasingly extensive range of monitors and can be used either as a unit dedicated to reproducing the LFE channel, or as a way to provide low-frequency extension and increased maximum SPL for the main loudspeakers.

“The O 810 and O 870 now make it possible to assemble flexible monitoring systems for different sizes of studios, with a smooth and uniform response that ranges from less than 20 Hz to greater than 20 Hz,” says Andrew Goldberg, product manager studio systems.

The built-in 7.1 Channel High-Definition Bass Manager(tm) is compatible with all formats from mono to the latest 7.1 high-definition systems, such as Blu-ray and HD DVD. Eight channels of analog, or an optional eight-channel 24-bit 192kHz digital input card, ensure flexible interconnectivity for modern studios. Four-mode LFE channel processing ensures maximum compatibility across all formats. Fourth order crossovers and flexible acoustical controls allow for seamless system integration. Built-in volume control allows for centralized system replay level adjustment independent of the source, and the electronics can be remote located to reduce cabling.

The latest amplifier technologies 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 down to 18Hz, even at high replay levels. Using the sum output, Plane Wave Bass Array(tm) (PWBA(tm)) techniques can acoustically improve lateral consistency in the listening area.

The O 810 and O 870 can be used in music, broadcast, and post production studios for tracking, mixing, and mastering. They may be positioned next to a wall or flush mounted into a wall, and can be mixed freely in multi-channel systems with other loudspeakers from the Klein + Hummel range. An extensive range of accessories further enhance the flexibility of the system. Both subwoofers are expected to be in stores this summer.
