PSB SubSeries HD10 review
The very compact (1 foot sq) SubSeries HD10 has the performance of a much
larger subwoofer and is perfect for people who want performance but do not
want to give up a large area of their room to do it. To overpower the laws
of physics the HD10 uses Dual Opposing Heavy Passive Radiators to
“fool” the HD10 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 a subwoofer less than a fourth
the size of conventional solutions of equal ability.
