Specs -- Carmelita Passive

Frequency response -- 30 Hz - 40 kHz +/- 3 dB on axis (in room)
Sensitivity -- 85 dB/1W/1m
Power handling -- 40W - 400W RMS/ch/8 Ohm recommended; higher than 400W risks damage; 120W nominal for max steady state SPL; 240W for full headroom for transients
Impedance -- 8 Ohms nominal (4 Ohms minimum at low bass frequencies only)
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
airLayer rolls off 2^nd order below 2 kHz, 1^st order above 6 kHz
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
Reduces room mode coupling and eases placement
Excellent phase alignment for soundstage focus
Vertical image stability
Minimal floor bounce effect
Recorded image height is well presented, even above tops of speakers

Stand-mount runs the speakers with a flat response for mounting on stands.
Bookshelf removes some energy in the 50 Hz band to counteract excessive wall reinforcement when placed very close to the front wall.

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

Two identical, 18 cm [7"], low mass, alloy cone, extra low distortion, low inductance, high resolution drivers with dual short circuit paths and heavy cast aluminum basket
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
Exceptionally low series resistance in crossover conserves damping factor and maximizes cone control

Sealed (acoustic suspension) for best woofer transient response, minimal group delay, and best integration with ESL array
High mass, 25 mm [1”] thick, well damped, well braced walls for negligible enclosure radiation
Baffle step is reduced with front edge scoops, which are also visually interesting

Single pair of binding posts, not for bi-amping
Bi-amping option available
Rhodium plated, solid copper Cardas Patented binding posts for spades or bare wire with a convenient, single clamping knob
5-way post option available

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

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
