Fohhn presents a new PS-9 active sub featuring an electronically controlled 21” woofer powered by a 8500 watts DSP amplifier.
Sub PS-9 active is a DSP controlled subwoofer with integrated 8500 watts CLASS D amplifier and a 21” woofer. The 21” speaker has a long excursion of 60 mm and an impedance of 0.5 ohms. The power output is equivalent to four high-power 18” woofers, the company says.
The excursion of the speaker membrane is controlled by DPC (Differential Pressure Control) technology, designed to generate high pressure levels and produce a tight, controlled bass response.
Subwave PS-9 active is designed for large venues, clubs or stadiums requiring higher levels of bass. It is also described as a good partner for WaveLine line array systems. The PS-9 active is equipped with DSP signal processors developed and made by Fohhn and can be operated and controlled via the Fohhn Net network. The wooden housing is finished with a PU coating.
During use, the supply to the amplifier is constantly monitored. If at any time it exceeds the maximum permitted range (180-255 VAC), the supply will be interrupted, the manufacturer says. During power up it also minimizes the input surge current by switching on at the mains voltage zero crossing.
Pricing & Availability
The PS-9 is expected some time in May, at a price of around €11,000.
