The PSB Speakers Alpha S10 has a DSP processor; the design scheme is phase-inverted with a backward port. The woofer diffusers are made of polypropylene; "on board" - a complete set of necessary adjustments (cutoff from 50 to 150 Hz, volume, phase).
The PSB SubSeries 250 model has a bass unit with a 10-inch diameter diffuser, and a Class D amplifier outputs 200 watts in constant and up to 600 watts in peak mode.
The PSB SubSeries 350 is already equipped with a 12-inch bass and a 300-watt amplifier. The functional equipment of the models is similar, there is a phase and signal level controller, a low-pass filter with an adjustable cutoff frequency.
The device has received 20-centimeter drivers with encore technology, which makes the sound even more powerful and clear. The subwoofer is also equipped with adjustable crossover and phase control, as well as RCA line inputs and a 12 volt trigger.
