[edit] Product Summary

• Manufacturer: B&W
• The DM605 S2 is unique answer to the problem of a system that deserves deep,

controlled bass extension when there is not the physical room to incorporate a separate subwoofer. The 130w amplifier is used to power the two bass drivers to give truly extended bass output.

• The mid-range and tweeter drivers are driven conventionally from the system amplifier, while

the two bass drivers are driven by the internal amplifier to give truly extended bass performance. Bass performance is further enhanced by Flowport technology, which smoothes the passage of air over both the internal and external port flares to reduce chuffing and improve detail. A separate line level LFE input can be driven directly from the subwoofer output on an AV processor or amplifier.

[edit] Technical highlights

• Nautilus Tweeter: B&W's Nautilus Tweeter technology ensures that the sound

remains focused and time-sensitive and that the stereo-image is presented with unparalleled three dimensional accuracy.

• Kevlar: B&W developed and patented the method of using Kevlar for

loudspeaker cones to reduce unwanted standing waves. DuPont originally created Kevlar for use in bulletproof vests.

• 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.
