SubSeries HD10
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.

SubSeries HD10 Reviews
- AV South Africa - SubSeries HD10
Its compact construction will be welcomed by many, especially since it sounds much bigger and more authoritative than its size suggests. - AV Magazine Brazil Subwoofer Review
With its excellent mechanical acoustic design, the small HD10 surprised everyone who was in the room during the tests, and can be easily compared to the best subwoofers three times its size. - Synchrony Speaker Review WSR
"Making disparate loudspeakers speak with one voice is a nearly impossible job to do, but PSB has done it."
