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.
