Specs -- Carmelita Active

  • Biamplified with electronic crossover and EQ
  • Frequency response -- 30 Hz - 40 kHz +/- 3 dB on axis (in room)
  • Peak SPL -- 105 dB (pair playing music at 4 m [13'] in mid-sized room -- 4.5 m x 7.3 m x 3.0 m (15' x 24' x 10')
  • Fully enclosed, not dipoles, makes placement easy
  • Listening area
    • Full spectrum 2 m wide @ 4 m (6.5' wide @ 13')
    • Very tight vertical dispersion and relatively narrow horizontal dispersion conserves recorded ambience, reduces interaction with the room, and sharpens the soundstage, yet is wide enough to avoid a headphone effect
  • Crossover -- 1st order @ 500 Hz -- far below the disturbance-sensitive hearing region of 1 kHz - 3 kHz; entire midrange and treble carried by the electrostatic elements; minimum phase operation through crossover region
  • Secondary partial crossover -- 1st order at 5 kHz -- limits upper treble from half width of ESL panel -- controls dispersion and flattens response without an electrical rolloff network
  • 2.5.5 way, quasi-line configuration
    • Woofer mounted below ESL array; ESL panels employ half-split-response (1.5 way ESL), additional woofer in back covering deep bass only
    • Woofer radiation pattern mates well to ESL array
    • Excellent phase alignment for soundstage focus
    • Vertical image stability
    • Recorded image height is well presented, even above tops of speakers
  • Four DSP presets; standard are: very near wall; normal; far; and console
  • ESL panels
    • One panel in each speaker, mounted in a barometrically isolated sub-enclosure, 18 cm wide x 20 cm high [7"H x 8"W]
    • Protected by an integral barrier
    • 260 square cm [40 square inch] forward radiating area per array
    • Tough, stable, injection molded, ABS stator frames
    • 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
      • Acts as a virtual air driver with force applied evenly over its whole surface -- no breakup, no coloration
      • Properly damped, unlike see-through electrostatics
      • Introduces absolutely no midrange or treble coloration, and distortion is far below audibility
      • Will not lose its tension or degrade over time
    • 1.5 way tweeter/mid design controls horizontal dispersion and eliminates electrical EQ network
  • Woofers
    • 16.5 cm [6.5"], paper cone, extra low distortion, low inductance, high resolution, very long excursion driver with neodymium magnet structure
    • Operate far below their breakup frequencies and their Xmax for practically no cone coloration
    • Seamless acoustical integration with the ESL
    • Strong, accurate bass, not boomy dance club bass
    • Direct connection to amplifier creates maximal damping factor and thus maximizes cone control
  • Enclosure
    • Sealed (acoustic suspension) for best woofer transient response, minimal group delay, and best integration with electrostatic panel
    • High mass, 25 mm [1”] thick, well damped, well braced walls for negligible enclosure radiation
    • Baffle step (diffraction interference) is reduced with front edge scoops, which are also visually interesting
  • Amplifiers
    • Input
      • True balanced XLR
      • Operates well, however, with RCA adapter (supplied upon request).
    • Input impedance: 10 kΩ balanced to ground
    • Maximum gain: 32 dB (x40 voltage gain)
    • S/N ratio: >113 dBA (20 Hz – 20 kHz, A weighted)
    • Damping factor: >1000 (20 – 1000 Hz)
    • Distortion: < 0.0005% (THD, DIM, SMPTE)
    • Mains power – <150 Watts playing music at full gain (assuming 12 dB crest factor, 6 Ω average impedance), <1A on 120V mains – 95% efficiency typical, starting from 1/8th maximum power -- very green
    • Works from any mains worldwide without adjustment
    • Built-in surge protection
    • IEC cord inlet with power switch -- uses standard power cords worldwide
  • Diaphragm polarization supply
    • Mains power -- 0.1 Watts to 1.0 Watts, depending on mains voltage -- very green
    • Works from any mains worldwide without adjustment
    • Built-in surge protection
    • IEC cord inlet with power switch -- uses standard power cords worldwide
    • No transformer or oscillator -- high reliability, and no radiated or conducted noise to affect your other components
  • Weight -- 16 kg [35 lbs] each
  • Dimensions: 43 cm high x 20 cm wide x 33 cm deep [17" H x 8" W x 13" D]
  • Heirloom quality materials and finishes used throughout for lifetime operation, yet all are recyclable
  • Designed, engineered and made in the USA
  • Warranty -- 5 years on all components against defects in materials and manufacturing
  • Modular construction and simple disassembly for straightforward repairs, even in the field
  • Miscellaneous
    • 10 mm [3/8"] thick, wool felt to kill internal edge diffraction
    • Appearance options available (custom finishes/paints, custom wood veneers)
