Key features 96 dB SPL 1W / 1m average sensitivity 75 mm (3 in) Interleaved Sandwich Voice coil (ISV) 450 W continuous pink noise power handling Weather protected cone and plates for outdoor usage Excellent transient response Ideal for compact two way, multiway systems and subwoofer applications Improved heat dissipation via unique basket design Description The 12W600 low frequency transducer meets the specific market requirement for a loudspeaker combining good linearity and efficiency with high power handling capabilities. Although primarily developed as woofer in compact reflex cabinets, the 12W600 driver’s versatile characteristics make it also suitable for bandpass. When used in a two-way system, we always recommend a 1.4" or 2" exit HF compression driver matching in order to achieve the best sound quality results. The high quality curvilinear cone assures smooth response and exceptional strength with maximum reliability under high mechanical stress. In the same way, the suspension geometry has been carefully designed for superior symmetry, resulting in DC offset free movement in a very low frequency area. The 75 mm ? state-of-the-art copper voice coil employs our Interleaved Sandwich Voice coil (ISV). A high strength fiberglas former carries windings on both the outer and inner surfaces. This results in a mass-balanced coil and an extremely linear motor assembly with a reduced tendency for eccentric behavior during high travels. The ferrite magnetic structure has been optimized using FEA CAD simulation software to maximize the flux density and symmetry in the voice coil gap region and to minimize weight. A new lightweight aluminum basket contributes the excellent weight-to-performance ratio of the transducer. Due to the increasing use of audio systems at outdoor events, the ability of the 12W600 to perform in adverse, high humidity weather conditions is a clear advantage. This has been achieved thanks to a proprietary water-repellent cone treatment. GENERAL SPECIFICATIONS ?
