Musway MWS822 20 CM (8) SLIM SUBWOOFER 250w rms D2. 20 CM (8) SUBWOOFER IN FLAT DESIGN. MUSWAY is known for its small and at the same time very powerful products. The two new flat subwoofers also join this tradition. Due to their design, they also suitable for installation locations that have little space in depth when shallow installation dimensions are a must. With an installation depth of 78 mm for the 8″ (20 cm) and a sensationally low 87 mm for the 10″ (25 cm) subwoofer, they are the ideal problem solvers for special installations. A particularly flat subwoofer should of course sound good and must be robust. That is why MUSWAY uses special and very hard cones made of the composite materials glass fiber and carbon. No savings were made on the drives either: the woofers have 40 or 45 ounce magnets and are driven by 50 mm 2 + 2 ohm dual voice coils, which are also very long wound. With Xmax values?? of +/- 15 mm, both woofers ensure a decent stroke. With 250 or 300 watts RMS, they are also very resilient, so that no compromises have to be made. 250 Watts RMS, 500 Watts Max.
