XB1
Subwoofer:
The Professional Monitor Company’s XB1 transmission line sub-bass
system is intended to supplement the output of smaller nearfield monitors
such as PMC’s DB15+, TB1S, GB1+ and FB1+ which it feeds as satellites.
Requiring no additional electronics or amplifiers the XB1 can be placed
out of sight and provides the answer to the problems of space and cost
by offering full frequency, high quality, high SPL monitoring.
