Midrange
Esotar² 430
The new Esotar² 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 excel-
lent inner damping.
The diaphragm and dust cap are molded as one piece. A new magnet/
motor system incorporates powerful neodymium magnets and a large
vented pole piece. The relatively large diameter aluminum voice coil wire
provides for a low moving mass, and is wound on an aluminum former to
maintain the extremely light weight.
Built into a rigid, die-cast solid aluminum frame with aerodynamically
shaped ribs, in conjunction with the powerful motor, the characteristic
Esotar² low-mass driver construction provides excellent transient re-
sponse, speed and precision, with smooth high frequency roll off and a
natural midrange reproduction. The Esotar² 430 driver exhibits very low
distortion even at extreme volumes, while the transparency and detail of
its midrange quality can best be described as holographic.
The Dynaudio Esotar² automotive loudspeaker series represent the high-
est level of automotive music reproduction – not just for Dynaudio but
for the entire arena of mobile audio. The compact Dynaudio Esotar² 430
expands the possibilities for system installations with a performance that
was previously not possible, and is a perfect complement to the perfor-
mance benchmarks set by the Esotar² loudspeaker separates.
