CDM 2SE
Stand - mount/Bookshelf loudspeaker system
The CDM 2SE is ideal for the smaller room, as it offers superb sound from a compact
enclosure.
An integral part of the CDM 2SE is the use of rounded baffle edges, which reduce the
effect known as diffraction. In normal cabinet construction, sound waves from the drive units
radiate toward both the listener and the cabinet edges. If the sound waves meet sharp
edges, they re-radiate towards the listener and, due to time delay, interfere with and blur
the sound coming directly from the drive unit. Rounding the edges reduces this time
smearing, giving you the listener a clearer sound and better defined stereo image.
Technical highlights
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.
