Technology - LEMS Driver





World’s best electrodynamic driver in terms of :

  • Linearity : > 99,5% linear at full excursion (8mm)

  • Resonance : no mechanical coupling of cone to basket, no surround, no spider

  • Distortion (no spider, no surround, minimum of moving parts and mechanical connections)

  • Qts : 0,25

World’s fastest driver

  • Not physically restrained by the mechanical suspension of spider and surround

  • Very low moving mass (only 15 grammes)

    • Low kinetic energy of moving mass

    • Less inertia problems

  • Optimized impulse and phase response for maximum transient response in the mid-bas frequency range.

  • Excellent power response** characteristics

LEMS technology


The combination of above mentioned qualities result in such a high level of detail and pureness of sound that you will experience the Ilumnia’s sound as real-life sound coming from a natural source and not from a speaker driver, just like we promised you...

**Power Response is the sum of the total radiated acoustic output of a loudspeaker as measured in a sphere around the speaker at several incremental intervals  on- and off-axis in the far (reverberant) field.  This measurement essentially captures the total sound emitted by a loudspeaker at all frequencies, in all directions, and is therefore thought by proponents of this measurement method to be more representative of how a speaker will sound in an acoustically well-balanced listening environment than by what can be inferred from a simple on-axis anechoic frequency response measurement.
