and a heavy-duty 8" woofer for high power
handling and extended low frequency
response. An acoustic bandpass filter design
eliminates the need for an external crossover.
The solidly constructed steel enclosure also
acts as a heat-sink to dissipate excessive heat
from the speaker component.Other
features include a paintable grille and
removable terminal block.Options include a
matching transformer for connecting the HB-1
to distributed speaker systems and a 900
Series Low Pass Filter Module for convenient
system equalization.The HB-1 also carries a
