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.
