Active bass reflex subwoofer

A 120 watt RMS class-D high performance amplifier, which is housed in the active bass reflex subwoofer of the Tempus series, provides the relentless powerful drive for the 300 mm long-throw woofer with its coated paper cone. With a Klippel-optimized magnet system and ventilated high-performance voice coil it is capable of generating a solid and voluminous, yet extremely precise deep bass range. To ensure no resonance or flow noise is produced, despite the huge movement of air that is created, the sturdy MDF housing has been equipped with elaborate bracing and two generously dimensioned Airflex ports. Volume, crossover frequency and phase can naturally be adjusted, while the active frequency response equalization system optimizes levels in the sub-bass range. The Tempus Sub 300A also features an automatic standby function with a power consumption of less than 0.5 watts.
