The vibration levels of the PV1 (red) are
compared with those of a conventional
subwoofer (blue) of similar bandwidth,
output capability and drive unit radiating

heavily braced wooden cabinet.
Measurements were made by scanning
the enclosure surfaces with a laser beam
and summing over the total area in each
case.
