Description

Description:

The new Esotar 430 midrange features a geometrically optimized 3.5” diameter MSP (magnesium silicate polymer) cone, a material providing the ideal combination of stiffness, low weight and excellent inner damping.

The diaphragm and dust cap are moulded as one piece. An internal double magnet motor system incorporates powerful neodymium magnets and a vented pole piece. The aluminum voice coil wire provides for a low moving mass, and is wound on an aluminum former to maintain an extremely light weight.
Built into a rigid, die-cast solid aluminum frame with aerodynamically shaped ribs, in conjunction with the powerful motor, the characteristic Esotar low-mass driver construction provides excellent transient response, speed and precision, with smooth high frequency roll off and a natural midrange reproduction.
The Dynaudio Esotar automotive loudspeaker series represent the highest level of automotive music reproduction – not just for Dynaudio but for the entire arena of mobile audio. The compact Dynaudio Esotar 430 opens up the possibilities for system installations, and is a perfect complement to the performance benchmarks set by the Esotar loud-speaker separates.
