Overview

SPIRE

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.

XStat™ Transducer
Advanced MicroPerf stator technology gives MartinLogan's latest-generation CLS™ electrostatic transducer almost twice as much exposed diaphragm surface as a traditional electrostatic panel of the same size. This dramatic increase in effective radiating area translates to higher efficiency and an even more effortless, unlimited dynamic presentation. The XStat pulls no punches!
But there's more to it than just putting more holes in the stators, which must maintain uniform spacing in front of and behind the diaphragm to exacting tolerances. They cannot flex. XStat's ultra-rigid aluminum AirFrame™ firmly anchors the transducer's working elements – stators and diaphragm – around their periphery, while ClearSpar™ spacers stiffen the assembly further across its width. ClearSpars enable precise, consistent tensioning of the Vacuum Bonded diaphragm without obstructing the floating, see-through look that is the visual hallmark of MartinLogan electrostats.
In the end, a speaker cannot outperform the signal feeding it. MartinLogan's state-of-the-art toroidal transformer and electrical interface engineering ensure an absolutely transparent link from amplifier to electrostatic panel. The result is sound of unparalleled purity, precision, clarity, and openness – the next best thing to no speaker at all.
