Together with the technical innovations for which B&W are famous, we have achieved this
supreme audio quality only by use of the very highest quality components. These include
B&W's unique Flowport™ system, new ultra-low frequency 15-inch drive unit which utilises
a stiffer, lighter die cast chassis to minimise unwanted resonances.
High power is essential in reproducing the exceptional bass demands of today's digital
audio recordings and movie sound tracks. The active 3rd order high pass and 4th-order
low pass line level filters with selectable crossover frequency, combined with variable gain
control and a phase reversal switch, allow tight matching between any other loudspeakers.
A passive 1st order speaker level filter gives flexibility for systems without preamp outlets.

Flowport™: Golf ball aerodynamics theory points the way towards lower
distortion reflex ports. Dimples improve the way the air flows over the surface of
any object. In the case of reflex ports, they offer a significant improvement over
simply flaring the port ends in reducing air flow turbulence at each end of the
port; so you get less chuffing noise and less compression at high sound levels.
