The Nautilus
TM
tube-loaded
tweeter ensures far greater
absorption of unwanted
radiation away from the
rear of the diaphragm.
Flowport is B&W’s familiar dimpled
design that reduces turbulence noise
to negligible levels.
It is located at the back on DM303,
DM309 and LCR3, and at the bottom
on ASW300.
