Augment the power of your mixing room, project studio, or any other monitoring setup with the KH 805 Active Studio Subwoofer from Neumann, a 10" woofer that reaches all the way down to 18 Hz, boasts 160W RMS / 200W peak power-handling, and features a multitude of ways to integrate with your existing set up; fourth-order crossover points, manual acoustic controls, four different routing modes, and remoteable electronics (requires optional kit)—all of these allow for greater ease and flexibility in implementation.

In addition to providing a loud and accurate low-end, the magnetically-shielded subwoofer increases the maximum SPL of your loudspeaker set up by up to 8 dB, while simultaneously decreasing any harmonic/intermodulation distortion that might be imparted by your main monitors. You can also use the KH 805 as a daisy-chain point for other subs.

Furthermore, this unit features a bass management design compatible with 2.1 systems (the common two monitor/one subwoofer arrangement) or 0.1 systems—surround 5.1, 7.1, etc. Thus, it is suitable for music mixing and surround applications, be they musical or post-production in nature.

Flexible Electronic Design

Bypassable fourth-order 80 Hz active crossover for compatibility with consumer reproductionFour routing modes on right input connector: right-channel bass management, LFE to subwoofer up to 120 Hz, wide for multichannel systems (where bass-management is the source), and Daisy Chain for subwoofer arraysSwitchable acoustic controls: Output level, low cut, parametric equalizer, and 45° step phase controlRemoteable electronics kit for less cabling and ease of use (available separately)Built-in limiter for amplifier/driver protectionLow heat dissipation

Powerful Driver and Cabinet Design

Extends frequency response down to 18 HzLow distortion due to magnetic shield and long throw driverReduced bass compression at high SPL reproduces bass frequencies in balanced proportionAllows main speakers to play louder with lower distortionWooden cabinet sports anthracite finish and high-density rubber isolating feet
