Key Features:

• The (Eighteen) 18 Sound 12W700 meets the specific market requirement for a loudspeaker which combines the excellent linearity, good efficiency and high power handling of the 15W700 model but in a 12 inch (300 mm) chassis for use in more compact systems.
• It is primarily intended for application in compact reflex and band-pass enclosures but can also be used for horn loaded configurations.
  The ribbed curvilinear paper cone has been made from a special high strength woodpulp 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, triple roll suspension made from a polycotton material which is more resistant to aging and fatigue than traditional cotton-based ones.
  The 75 mm (3 inch) diameter 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 FEACAD resource to maximize the flux density in the voice coil gap.
• Voice coil cooling has been achieved by incorporating airways between the chassis back plate and the top plate of the magnet, allowing heated air from the voice coil and gap to be channeled away and dissipated by the chassis basket.
  Due to the increasing use of audio systems at outdoor events, the ability to perform in adverse weather conditions or in high-humidity areas is an essential feature of the 12W700.
• This has been achieved using an exclusive cone and magnet plate treatment process which increases resistance to corrosion and renders the cone water repellent.
