    • Tight 5° vertical dispersion at 15 kHz
    • Controlled dispersion -- uniform frequency response over a known angle; rolls off rapidly beyond
      • conserves recorded ambience
      • sharpens the soundstage
      • reduces interaction with the room, especially reducing wall splash
  • involves the room enough, however, to avoid in-your-head imaging
  • Remote control: level, mute, input, preset, on/standby
  • Inputs
    • Analog
  • Balanced XLR in and through
  • Single ended RCA in and through
  • Digital
  • AES (balanced XLR)
  • Optical S/PDIF (TOSLINK)
  • Coax RCA S/PDIF
  • All have through outputs, except optical sends its through data from coax output
  • Input circuit automatically engages whichever input has a signal
  • Adjustable gain by way of remote control; no effect on resolution or S/N
  • Crossover: 2nd order @ 500 Hz
    • Far below the disturbance-sensitive hearing region of 1 kHz - 3 kHz
    • Entire midrange and treble carried by the electrostatic elements
    • DSP (Digital Signal Processing) implementation, which functions exactly according to design intent, unlike complex passive crossovers
  • Secondary partial crossover on electrostatics
    • Resistor-only 1st order passive at 5 kHz
    • Limits the upper treble from half the width of ESL panel
    • Controls dispersion and flattens the electrostatic aperture effect roll-up response without an electrical rolloff network
  • Built in equalization
    • Idealizes the frequency response
    • Provides three room boundary reinforcement corrections, selected with the remote control
    • Adapts the bass response to a wide range of speaker placements relative to walls, or can be used to boost or cut bass
  • airLayer feature
    • High grade, silk ring-dome tweeter mounted on outboard side of each speaker
    • Adjustable level from off to overly loud
    • Its sound is reflected from each near side wall
    • 2nd order crossover at 2 kHz
    • When adjusted to be just slightly on, enhances the sense of spaciousness
    • When adjusted to higher volume, provides extra treble for informal, off-axis  listening
  • Driver configuration
    • 2.5 way, WTW (Woofer - Tweeter - Woofer) quasi-line
    • Woofer radiation pattern mates well to electrostatic array
    • Reduces room mode coupling, eases placement
    • Excellent phase alignment for image focus
    • Vertical image stability
    • Minimal floor bounce effect
  • Electrostatic panels
    • Two identical panels in each speaker, mounted in a barometrically isolated sub-enclosure
    • Vertical array; 7” x 16
    • Protected by an integral barrier
    • 80 in2 [520 cm2] forward radiating
    • Tough, stable, injection molded stators
    • 66-element, parallel wire, stator electrodes (total of 132 electrode elements per panel)
    • Unique panel construction and materials are immune to the effects of wide and rapid temperature and humidity swings
    • Optimal sonic membrane material
  • Thickness less than 1/15th of a sheet of 20 lb. paper -- lighter than the air it is driving (air load exceeds in-band mass load)
  • Acts as a virtual air driver with force applied evenly over its whole surface -- no breakup, no coloration
  • Properly damped, unlike see-through electrostatics, for most accurate transients
  • No midrange or treble coloration
  • Distortion is far below audibility
  • Will not lose tension or degrade
  • Woofers
    • Two identical, 8” [25.5 cm], low mass, long excursion, alloy cone, low distortion, low inductance, high resolution drivers connected in parallel
    • Operate far below their breakup frequencies for nearly ideal pistonic motion and thus practically no coloration
    • Seamless integration with the electrostatics
    • Strong, accurate bass, not boomy club bass
    • Tight, palpable impact and slam
    • Direct connection to the amplifier eliminates the effects of speaker cables
  • Enclosure
    • Sealed --fast woofer transient response, low group delay, tight integration with electrostatics
    • Walls high mass, 1” thick [25 mm], well damped, well braced; negligible vibration
    • 2.5” [63 mm] thick, solid hardwood baffle is stable and rigid, yet free of resonances
    • Baffle step is reduced by front edge scoops, which are also visually interesting
    • Modest backward tilt
  • Maintains time alignment between drivers and thus sharpens image
  • Causes the image to appear above the speakers, not from down on the floor
  • Plinth
    • 2.5” [63 mm] thick
    • Solid, hard maple, painted to match cabinet
    • Choice of high durometer rubber feet or spikes
  • Amplifiers
    • Two amplifiers in each cabinet, one for the woofers and one for the electrostatics and airLayers
    • Input impedance (analog)
      • XLR: 44 kΩ, balanced to ground
