The new PS-850 is a passive subwoofer with direct radiation, vented enclosure and Non-Turbulent Port (NTP) design. The system is equipped with two high performance 18″ long excursion chassis with 4.5″ voice coil and water-resistant cones. Its nominal power rating is 2000 W.
The subwoofer is designed for exclusive use with the amplifiers from Fohhn’s DI-Series: This guarantees optimal performance and protection of the speaker.
The PS-850’s enclosure is made from high-quality multiplex birch plywood and finished with a black scratchproof polyurethane coating. For optional weather protection, the subwoofer is also available with additional water-repellent speaker cone impregnation. The front grille is backed with acoustic foam and powder coated in the same colour as the enclosure.
On the rear of the enclosure are two recessed Neutrik NL4 Speakon connectors – this enables the subwoofer to be set up directly against a wall without the cable bending.
The PS-850 is additionally equipped with two further Speakon connectors on the front. In a cardioid setup, this enables the amplifier signals to be seamlessly looped through – on the back of a stack or array. The amplifiers include respective presets for cardioid operation.
The new subwoofers also work as a Focus Sub Array: When used with the new DSP amplifiers, the beam characteristics of a vertical or horizontal bass array can be electronically controlled in real time, using a PC and free Fohhn Audio Soft control software. All settings can be saved as presets and recalled at the touch of a button in changing sound reinforcement situations. No complex re-rigging is needed.
The PS-850 is equipped with numerous mounting points and features designed to make transportation and on-site setup much easier.
