18 Sound 12LW1400
SMALL SPECIFICATIONS
96 dB SPL 1W / 1m average sensitivity 100 mm (4 in) Interleaved Sandwich Voice coil (ISV) 900 W continuous pink noise power handling Weather protected cone and plates for outdoor usage Double Silicon Spider (DSS) for improved excursion control andlinearity Demodulating Ring for lower distortion Improved heat dissipation via unique basket design Specially designed for high loading compact enclosures
The 12LW1400 is a low frequency loudspeaker which sets a new industry standard in 12" (300 mm) 4" voice coil high performance transducers, already accomplished by the 15LW1400 and 18LW1400 respectively.
It has been designed for use as a subwoofer or low frequency component in multi-way systems where considerable amounts of power and low distortion are needed. It is ideally suited for very high loading situations, such as bandpass, horn loaded or compact reflex configurations. In its reflex configuration, it can be used in extremely compact enclosures (30 - 60 lt), making the 12LW1400 ideally suited for touring applications, sound reinforcement or fixed installations, including indoor and outdoor concert reinforcement systems.
Maximum strength, smooth response and high displacement piston motion are obtained using Double Silicon Spider technology (DSS) and a large excursion surround. A special formulation cone material has been used to enable it to withstand high loading and high power peaks. The suspension system has been designed to give symmetric large signal behavior across the whole working range, providing low harmonic distortion at different excitation levels.
A new state-of-the-art voice coil, based on Interleaved Sandwich Voice coil (ISV) provides high levels of thermal stability and durability. The ISV technology is based on a high strength fiberglas former with half the coil wound on the outside and half on the inside ensuring uniform thermal dissipation on both sides. It is bonded together using unique high temperature resin adhesive to achieve a balanced and solid linear motor unit.
Great care has been taken to symmetrize all non linear characteristics, mechanical as well as electromagnetic. Customized Double Demodulation Rings technology (DDR) has also been used to further improve the performance of this speaker. This technology dramatically reduces the intermodulation and harmonic distortion whilst improving the transient response.
The top plate and back plate design have been optimized for cone excursion and maximum symmetric force factor by the use of in-house FEA Magnetic simulation software.
Furthermore, excellent heat dissipation has been achieved by the special basket design which incorporates air channels between the basket and magnetic top plate.
The speaker is able to perform properly under inclement weather conditions due to an exclusive cone treatment which improves pulp strength and gives water repellent properties to both sides of the cone. In addition, the special treatment of both the top and back plates makes them far more resistant to the corrosive effects of salts and oxidization. This treatment is far more effective than any other treatment in use today.
