OPIS:

The E15-200S is a fine example of a high quality transducer providing the right balance between performance and engineering costs. This ferrite low frequency driver satisfies the demand for a 15" loudspeaker which combines excellent linearity with good sensitivity and power handling characteristics. The E15-200S has been designed for two-way or multi-way reflex systems. When used in a two-way system, we recommend a 1" exit HF compression driver match for the best sound quality results. The high quality paper cone has a smooth, P.audio specified curvilinear profile design that eliminates bell-mode resonance within the intended frequency range. The cone is carried by a specially treated and dampened double half-roll linen suspension designed to control excursion while maintaining piston action linearity. Voice coil cooling has been achieved by incorporating airways between the chassis back plate and the magnetic top plate, allowing heated air from the voice coil and gap to be channeled away and dissipated by the chassis basket. This technology is the result of a meticulous 3D CAD design project.
