Take your professional audio production to the next level with the Neumann KH 870 Dual 10" Active Studio Subwoofer. Designed for precision in tracking, mixing, and mastering across music, broadcast, and post-production environments, this subwoofer is a testament to Neumann's commitment to high-quality sound reproduction.
The KH 870 stands out with its advanced 7.1 HD Bass Manager, ensuring full compatibility with audio formats ranging from mono to the latest 7.1 high-definition systems. This feature allows for a seamless integration into any professional setup, providing a robust and flexible bass foundation for your audio work.
Equipped with dual 10" front-firing drivers, the subwoofer delivers deep and powerful bass frequencies down to 18Hz, offering up to 6dB more output compared to single-driver models. The magnetically shielded drivers ensure that you can place the subwoofer near video monitors and sensitive electronics without interference.
The bass-reflex cabinet, constructed from rigid wood and finished in a durable anthracite paint (RAL 7021), is designed to minimize resonance and provide stable, distortion-free low frequencies. The front-panel bass ports enhance the low-frequency response while reducing compression and turbulence, allowing for flexible placement options, including wall or flush mounting.
The KH 870's integrated electronics feature a bypassable 4th order 80Hz active crossover, ensuring compatibility with a wide range of consumer formats and smooth system integration. The subwoofer also boasts an 8-channel system volume control and an RS-232 port for optional remote control, enabling centralized system management and reducing the need for extensive cabling.
For those seeking even more control, the subwoofer includes 0 and +10dB LFE gain settings and 4-mode LFE processing. These options guarantee compatibility with all industry standards and facilitate the creation of complex audio setups, including daisy-chaining with additional subwoofers and external signal processors.
Connectivity is a breeze with support for 8 channels of analog audio via XLR connectors, and the option to expand with a 24-bit/192kHz digital input card for digital audio channels. The sum output feature allows for the creation of larger systems and Plane Wave Bass Arrays, enhancing the consistency of bass across the listening area.
The KH 870 is also equipped with various acoustic controls, including output level, low cut, parametric EQ, and 45-degree step phase control, complete with a built-in test signal. These controls enable precise calibration to match the subwoofer to your specific work environment and system components.
The internal amplifiers boast a peak output of 400W with low heat dissipation, ensuring powerful performance without overheating. An integrated electronic limiter provides additional protection for the amplifiers and drivers, promoting long-term reliability.
For added versatility, the subwoofer supports mounting options for a main loudspeaker, allowing the creation of a large 4-way column system. A range of accessories, including remote controls, cables, and flight cases, are available to maximize the potential of the Neumann KH 870 Dual 10" Active Studio Subwoofer in any professional audio setting.
