The 18LW800 is a low frequency loudspeaker which meets the demand for a transducer with high linear travel and high efficiency values.
It has been designed for use as a low bass or sub-woofer component in a reflex configuration, in high power fixed or touring loudspeaker systems. It provides clean, linear, undistorted low frequency reproduction at high power levels. In its reflex configuration, it is also suited to bass musical instrument applications, especially the 5- string fretless bass guitar.
The curvilinear paper cone has been made using a special high strength wood pulp and designed to achieve the best possible linearity within its intended frequency range as well as control bell-mode resonances around the cone circumference. This cone is carried by a double half-roll suspension formed of a linen-like material, which is more resistant to aging and fatigue than the traditional cotton-based materials of conventional surrounds.
The state-of-the-art voice coil employs our own Interleaved Sandwich Voice coil (ISV) technology in which a high strength fiberglas former carries windings on both the outer and inner surfaces. This results in a balanced coil with a uniform distribution of mass and motive energy, providing an extremely linear motor assembly.
Excellent heat dissipation has been achieved by incorporating air channels between the basket and the magnetic top plate.
Maximum flux concentration and force factor in the gap are assured by the unique shape and design of the top and back plates, which have been researched and designed using our in-house magnetic flux FEA CAD resource.
Due to the increase in use of audio systems at outdoor events, the ability of the 18LW800 to perform in adverse weather conditions or in areas of high humidity is a great advantage. This has been achieved using exclusive cone and magnetic plate treatment processes, which resist corrosion and render the cone water repellent.
