B&W DM550 speakers - black / grey :
DM550 Stand-mount / Bookshelf loudspeaker system :
Product Summary :
• The tailored two-way closed box design incorporates a 6in bass/midrange driver with a large magnet assembly thrusting high pressure sound reproduced to precise limits dictated by the dimensions of small enclosure
• A one piece moulding has been used to strengthen the cabinet rigidity between drivers and front baffle. The metal-domed high frequency unit dictated by CAD allows the simplest of crossovers to be used
All of which increases cost-effectiveness without impairing linearity
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 cabinets feature a specially designed high density front baffle which achieves almost Matrix-like stability in strengthening overall enclosure construction. The bevel edges of the front moulding reduce diffraction and improve dispersion
• The crossover components use heavy gauge wire throughout and new drivers guarantee not only high reliability but ensure that top specifications are met
