(Per Pair)



  • 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 good specifications are met.

  • 1 x 26mm high-frequency with aluminium dome, One 26mm coil on aluminium former, wound with polymide resin and heat cured
