Eighteen Sound 15W750

The Eighteen Sound 15W750 speaker   combines good linearity and efficiency with excellent power management capability. Although it is intended primarily for use in reflex tuned boxes, the versatile features of the 15W750 make it suitable for a wide variety of uses. It can be used as a subwoofer or as a bass route in 2-way full-range systems. In the latter case, the parent company recommends coupling with compression drivers with 1.4 "or 2" throat exits.

The paper cone involves the use of a special high-strength wood pulp and is designed to obtain the best possible linearity of response. In addition, an unusually deep robust triple-wave suspension supports the cone. The front suspension is made of a linen-like material, which is more resistant to aging and wear.

The 75 mm (3 ″) aluminum coil uses ISV - Interleaved Sandwich Voice Coil technology , in which a high-strength fiberglass support supports the windings on both surfaces to obtain a balanced coil with a uniform mass distribution and motive energy. All this translates into an extremely linear motor unit.

Air ducts between the basket and the rear magnetic plate guarantee excellent heat dissipation. In addition, air vents in the back plate provide additional ventilation by forcing the flow directly to the air gap. Furthermore, considerable attention characterizes the design of the magnetic structure in order to maximize the concentration of the flow and the force factor in the air gap.
