PSB SubSeries HD8

The very compact (less then 1 foot sq) PSB Speakers SubSeries HD8 has similar performance to it's slightly bigger brother the HD10. To overpower the laws of physics the HD8 employs Dual Opposing Heavy Passive Radiators to “fool” the HD8 cabinet into behaving as a much larger enclosure with much larger, longer ports. The results of this design should be obvious to all: Deep, powerful, high impact reproduction of even the most challenging soundtracks and musical performances from an incredibly small subwoofer—less than a fourth the size of conventional solutions of equal ability.
