Key Features:

• The (Eighteen) 18 Sound 15W700 low frequency transducer meets the specific market demand for a loudspeaker which combines good linearity and efficiency with high power handling capabilities, containing a 75 mm Ø aluminum voice coil.
• Although primarily intended for use in tuned reflex enclosures, the versatile characteristics of the 15W700 render it suitable for a wide variety of enclosure types, particularly as a subwoofer or as a LF driver in 2 or 3-way systems.
• When used in a 2-way system, we recommend a 1.4″ or 2″ exit compression driver in order to obtain the best sound quality.
• The deep profile 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 and to control bell-mode resonances around the cone circumference.
• The cone is carried by an unusually deep profile, double half-roll suspension formed of a linen-like material which is more resistant to aging and fatigue than the traditional cotton-based materials used in conventional surrounds.
• The 75 mm Ø aluminium voice coil employs the Interleaved Sandwich Voice coil (ISV) technology, in which a high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil.
• This results in an extremely linear motor assembly with a reduced tendency for eccentric behavior when driven hard.
• The magnetic structure has been optimized using our in-house FEA CAD resource that has maximized the flux density in the voice coil gap.
• Excellent heat dissipation has also been achieved by incorporating air channels between the basket and the magnetic top plate.
• Due to the increase in use of audio systems at outdoor events, the ability of the 15W700 to perform in adverse weather conditions or in areas of high humidity is a great advantage.
• This has been achieved using exclusive treatments which enable the cone and the magnetic plate to resist corrosion and render the cone water repellent at the same time.Designed & manufactured in Italy and provided exclusively by Lean Business, this Eighteen Sound speaker comes complete with 2 years warranty.
