The very compact (less then 1 foot sq) 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
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.
