DM640i
Floor-standing loudspeaker system
Product Summary
G
Designed with the more demanding digital sources of the nineties in mind, the 600 series has
earned a reputation for minimal coloration and musical accuracy in audio reproduction.
Successfully capturing the transients found in music meant developing a loudspeaker able to
do justice to the attack of the original audio signal.
Designed by a master of industrial design Dr Kenneth Grange, the cool, dark lines of the
600 series cabinet are perfect partner for contemporary furniture and interior design settings.
G
The profound low frequency response is achieved by the use of heavier Cobex cones in the
two 8in bass drivers, delivering a lower fundamental resonant frequency. The midrange unit is
a separate, acoustically isolated Kevlar driver mounted in its own sub enclosure.
G
This has been enhanced in the DM640 by taking the Silver Signature Kevlar cone profile,
and introducing a new rubber surround, making it identical in every respect to the Kevlar
driver in the much acclaimed B&W Matrix 805.
G
The crossover has been revised to accommodate the changed response of the new midrange
drive unit.
Technical highlights
G
B&W 's Tweeter technology ensures that the sound remains focused and time sensitive and
that the stereo image is presented with unparalleled three dimensional accuracy.
G
The strict acoustic requirements of the cabinet have dictated a front baffle moulding of extra
high rigidity. The polymer has been chosen for its composition and ability to reduce unwanted
resonances to a minimum.
