C4128 TWO WAY SPEAKER SYSTEM The C4128 is a full range two way high sensitivity passive system, compact and versatile. The C 4128 is a two-way, dual woofer, passive loudspeaker designed to provide extended low frequency performance from a compact vented enclosure. It features advanced technology, latest generation transducers: the 8” woofers are equipped with a 2” voice coil and the 1” neodymium compression driver is equipped with a 1.5” voice coil, mounted on a rotatable 90 x 70 constant directivity horn, providing very natural sound reproduction. It is the optimum choice for a variety of fixed or portable applications, thanks also to the pole mount, the very light weight and small size. p/n. 130.00.170 It features four M10 mounting points for horizontal or vertical U-bracket, cabinet is asymmetric (15 and 45) for versatile ceiling/ wall installation and floor monitoring operation. The C4128 can be used as a main speaker in small-medium, near field systems or as a fill/delay element in bigger systems. The design also permits optimum use in Theatre ‘Under Balcony Applications’. The wide coverage angle and the true constant directivity of the newly designed horn make the coverage of a large audience very easy; the crossover design guarantees the perfect pattern matching of woofer and compression driver and includes active electronic protection for the driver. The possibility to rotate the horn optimises both horizontal or vertical installations.
