Sound output due to cabinet vibration

low-pass filter 80Hz
EQ = i
EQ = ii
EQ = iii
Bandpass output level 90dB at 1m
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
area, but using a single 250mm driver in a
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.
