Martin Logan Spire Electrostatic Speakers
|
The first new MartinLogan speaker of the CLX generation, Spire marks
a new paradigm for high-performance sound. Crossover engineering
derived from the CLX loudspeaker seamlessly blends the high-resolution
XStat™ and PoweredForce™ drivers.
Revealing every subtle nuance of recorded sound with unflinching
accuracy, Spire's ultra rigid AirFrame and curvilinear XStat
electrostatic transducer reveal a magical performance with precision,
dynamics and three-dimensional sound staging. Housed within an
ultra-rigid, extruded aluminum and composite AirFrame™, Spire's CLS™
(Curvilinear Line Source) XStat™ transducer builds upon the legacy of
MartinLogan's 25 year heritage of providing the highest quality
electrostatic products.
