Bowers & Wilkins DM620i Manual, Specification Sheet

DM620i
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 bass units have been upgraded with a new cone and surround assembly, injection
moulded with revised materials and geometry. The surround is now moulded directly onto the
cone, forming a welded joint, which is more consistent and far more secure than its glued
equivalent.
●
The response of the improved bass units is significantly smoother and requires less correction
by the crossover network. The number of components has been reduced accordingly, which
helps lessen the degradation of the signal.
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.
