B & W ’s Active Subwoofer Series
Product Summary
●
Coloration is reduced to negligible proportions by the proprietary B&W Flowport™ design
and substantial internal cabinet bracing. A separate decoder input socket, which has its
own volume control calibrated to the standard THX input level, facilitates calibration of your
home theatre installation. Added to your home cinema system, the ASW 4000 produces
unrivalled bass response and impact. One which will truly complete the dynamics of the
home cinema experience. Immaculately finished in your selection of real wood veneers Black Ash, Cherrywood or red-stained Cherrywood, this active subwoofer is designed to
complement the new Nautilus 800 range of loudspeakers - truly the connoisseur's choice.
●
The powerful, low distortion 15inch driver, derived from the Nautilus™ 801 features a 4in
voice coil, double rear suspension and Kevlar® reinforced cone. The 450 watt amplifier
gives sustained ultra-low bass performance of true weight and precision and to a level
capable of filling the larger room with just one unit. A separate, calibrated decoder input
facilitates the set-up of your home theatre installation.
Technical highlights
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.
Matrix™: The basic construction of nearly all loudspeakers is exactly the same -
panels of wood-based materials, bonded to form a rectangular box. B&W
studied and evaluated how each aspect of cabinet behaviour and the efficiency
of various materials and construction methods affects sound.
