Klein + Hummel unveils studio subwoofers O 810 und O 870 at prolight+sound 2008

A profusion of developments in transmission technologies has increased the demand for professional monitoring systems. Modern production facilities require high quality monitoring systems that can accurately reproduce anything up to the latest 7.1 discrete high definition formats. Meeting these demands, Klein + Hummel unveiled the O 810 and 0 870 subwoofers at prolight+sound show 2008 in Frankfurt. Shows featuring the subwoofers in 2008 include 125th AES, San Francisco in October, PLASA 2008 in London, 124th AES in Amsterdam as well as IBC 2008.
It is the perfect compliment to Klein + Hummel’s increasingly extensive range of monitors and can be used either as 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 sized of studio, with a smooth and uniform response that ranges from less than 20 Hz to greater than 20 kHz,” says Andrew Goldberg, Product manager Studio Systems.
The built-in 7.1 Channel High Definition Bass Manager is compatible with all formats from mono through the latest 7.1 high definition systems such as Blu-ray and HD-DVD. Eight analogue channels or an optional 8-channel 24-bit 192 kHz digital input card provide versatile interconnectivity. Four-mode LFE channel processing ensures maximum compatibility across all formats. 4th 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 provide a tight, articulate, and distortion-free low frequency reproduction down to 18 Hz, even at high replay levels. Using the sum output, Plane Wave Bass Array (PWBA) technology can acoustically improve lateral consistency in the listening area. The O 810 and O 870 are suitable for 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 comined easily in multichannel systems with other loudspeakers from the Klein + Hummel range. An extensive range of accessories further enhance the flexibility of the system.
