| 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 Specifications : -:®:- Vintage : 1991 model -:®:- Frequency Range : 56Hz to 30 kHz [-6dB points] -:®:- Bass Loading : Second-order closed box alignment -:®:- Frequency Response : 75Hz to 20kHz, ±2.5dB on reference axis -:®:- Dispersion : 20Hz to 15kHz : Vertical : ±2dB over 10° arc, Horizontal : ±2dB over 40° arc -:®:- Sensitivity : 87dB [2.83V/1m] -:®:- Distortion [For 90dB at 1 m] : Second Harmonic: Less than 3% at 20Hz to 200 Hz, Less than 1% at 200Hz to 20kHz Third Harmonic: Less than 2% at 20Hz to 200Hz, Less than 1% at 200Hz to 20kHz -:®:- Impedance : Nominal 8ohms [not falling below 4ohms] -:®:- Crossover : third-order acoustic response low-pass and high-pass -:®:- Drive Units : 1 x 26mm high-frequency with aluminium dome, with 26mm coil on aluminium former, wound with polymide resin and heat cured, -:®:- 1 x 160mm bass/midrange with composite short fibre, 26mm coil on high temperature former, wound with polymide resin and heat cured -:®:- Power Handling : Suitable for amplifiers with 10W to 75W output -:®:- Dimensions [H x W x D] : 352 x 204 x 243mm (13-7/8" x 8" x 9½") -:®:- Weight : 5.5kg each (12 lbs), - packed 14kg one box SOLD May 2017 on trademe to New Plymouth |
