Neumann KH 870

It is worth mentioning that the DSP, which uses a high-quality A/D converter from BurrBrown, only filters the woofer of the subwoofer. The signal path for the satellite speakers remains purely analogue and undergoes no A/D, D/A conversion. With the "Pure Satellite" function, when activated, the subwoofer and the DSP filter section are bypassed completely. In this case, the satellite signals are routed unfiltered to the outputs and only the volume of the satellites can be varied.The volume of the subwoofer and the entire stereo system can be controlled using the remote control supplied as standard with the subwoofer - all from the comfort of your listening position.The special feature of our extremely powerful and high-precision subwoofers is the passive cone used, which replaces the usual bass reflex channel. This design completely eliminates disturbing flow noise caused by air turbulence. Audible tube resonances (with lambda/2 + multiples) are due to the principle of an open tube on both sides (bass reflex channel) and can be eliminated with the passive membrane design in all EVE Audio subwoofers. Furthermore, the suspension of the passive cone has a restoring force below the tuning frequency, which reduces inaudible subsonic excursions. This means less excursion in the operating range and thus reduced intermodulation distortion.A passive diaphragm enables a particularly low tuning or lower cut-off frequency in a compact housing.

The Sub8 is a powerful active subwoofer with small dimensions that extends the playback range to below 30 Hz and can be customised in many ways to suit the acoustic conditions.It contains a special long-throw 8.5" chassis, which is driven by a powerful magnet and a 38 mm voice coil. ICE modules are used as amplifiers, which combine high performance with minimal heat generation and can easily cope with high loads over long periods of time.There are control options for volume (-60 to +6 dB) and phase switching (180°). Furthermore, the upper cut-off frequency of the subwoofer can be variably adjusted (50 - 150 Hz). A filter can be switched on for the satellite outputs, which blocks the signals from the satellites below 85 Hz, for example to reproduce a film soundtrack in accordance with Dolby® and relieve them of the low frequencies. It is also possible to either switch the subwoofer on or off manually or have it switch on automatically as soon as it receives signals (signal-on/continuous).The remote control supplied allows these controls to be set conveniently from the listening position.

In recent years, the audio industry has produced a large number of new, high-quality multi-channel audio formats, which place considerably higher demands on the professional production environment in the studio. The Blu-ray format, for example, makes it possible to store an increased number of discrete audio channels with high resolution (7.1). To meet these requirements, Neumann has created a 7.1 High Definition Bass Manager with the newly developed electronics of the KH 810, which fulfils all studio requirements from mono to the latest 7.1 HD formats. With eight analogue input channels, flexible connection is guaranteed in the modern studio environment. Four switchable LFE modes guarantee compatibility with all formats and industry standards. Extensive acoustic adaptation options and a frequency separation of 24 dB/oct allow optimum integration into the existing studio acoustics. The built-in 8-channel volume control in conjunction with the optionally available wired remote control can be used to realise source-independent central system control. The electronics of the KH 810 can be detached in order to adapt the cabling flexibly. The latest amplifier technology and extensive research and optimisation of the speaker chassis used have resulted in the highest degree of bass precision and sound neutrality. The low-resonance cabinet and the flow-optimised bass reflex channels ensure dry and extremely low-distortion bass reproduction down to 18 Hz, even at high levels. Multisubwoofer systems can easily be set up using the sum output of the electronics. This allows speaker arrangements such as Plane Wave Bass Arrays TM (PWBA) to be implemented, which dramatically improve the lateral mode behaviour in the listening room via cylindrical wave generation. The KH 810 was developed as an extension of our extensive range of studio monitors. It can be used alone or in combination with several subwoofers to realise large systems with very high maximum level requirements. The KH 810 is therefore the ideal low-frequency extension for music, broadcasting and post-production for use in tracking, mixing and mastering. It can preferably be positioned close to the wall or, thanks to the bass reflex ports on the front, in the wall and can be freely combined with all our monitors in multi-channel systems.

The T10S is a powerful yet compact 10-inch active subwoofer designed to extend the bass response of nearfield monitors. At the same time, the subwoofer's performance, features and connectivity are specifically matched to ADAM Audio's T5V and T7V studio monitors.Equipped with a down-firing 10˝ woofer and a superior 130 watt Class D amplifier, the T10Soffers a frequency response of 28 Hz to 120 Hz and an impressive maximum sound level of 104 dB SPL. An adjustable low-pass filter can be used to adapt the bass signal to the monitors in order to get the best out of the overall system. Further adjustment options on the rear of the subwoofer allow it to be adapted to the room acoustics or the satellite speakers.Visually, the T10S follows the clear lines of the T series and its dimensions make it one of the most compact subwoofers in its class. This makes it easy to integrate into any studio environment. The acoustic performance has been optimised by means of four decoupling rubber feet and a generously dimensioned bass reflex port.
