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.
