Specifications A great sound for these small bookshelf speakers, made of cherry wood. High quality tweeter, and bass/midrange driver. The advantage of ribbon drive units is that the ribbon-shaped metal aperture - in this case 60 x 8 mm - is also the coil to which the signal is fed, so there is no risk of loss due to membrane coupling or resonance. The unit has a cast chassis of 135 mm and a cone made of a metal alloy with a diameter of 100 mm, made of a mixture of aluminium, titanium and magnesium. Dimensions 32 x 24 x 21 cm Power 50 watts Peak 80 watts The set will be packed carefully and shipped by insured mail to mainland destinations.
