Bowers & Wilkins DM630i Speaker User Manual

Floor-standing loudspeaker system
Product Summary
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.
The DM630 delivers a more profound bass delivery via the larger 52-litre enclosure.
The high excursions needed to extend the low frequency range to 40Hz are provided by two
active 8in bass units which enable higher system power handling by sharing the LF load
The bass is augmented by a rear facing port with a range of port lengths to allow for bass
response adjustment of the system to reflect the listeners taste.
Technical highlights
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.
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.
