Very compact at only 38" tall, but they project the soundstage of a huge speaker!


JANSZEN zA2.1 SPECIFICATIONS



Frequency response -- 30 Hz - 20 kHz +/- 3 dB on axis (in room)

Sensitivity -- 87 dB/1W/1m (pink noise)

Power handling -- 25W - 150W RMS/ch/8 Ohm recommended; up to 250W tolerated (500W/4 Ohm)

Impedance -- 6 Ohm nominal, 4 Ohm min., 10 Ohm max.

Peak SPL from pair playing music

108 dB at 4 m [13'] in mid-sized room - 4.5 m x 7.3 m x 3.0 m [15' x 24' x 10']

114 dB at 2.5m [9'] in small room - 3.7 m x 4.9 m x 2.7 m [12' x 16' x 9']

Fully enclosed, not dipoles, eases placement

Listening area

Full spectrum 1 m wide @ 4 m (3.5' 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

2.5 way, WTW (Woofer - Tweeter - Woofer) configuration

Woofers above and below ESL array; ESL panels employ half-split-response (1.5 way ESL)

Woofer radiation pattern mates better to ESL array

Reduces room mode coupling and eases placement

Excellent phase alignment for soundstage focus

Vertical image stability

Minimal floor bounce 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 -- limits upper treble
from half width of ESL panel -- controls dispersion and flattens
response without an electrical rolloff network

Woofer level -- three settings - autoformer maintains damping factor and cone control -- no resistive divider

Intimate Mode -- on-axis seating

Intimate A: +3 dB -- compensates for when speakers are
placed far from front wall (or boosts bass a bit near front wall)

Intimate B: 0 dB -- for speaker placement near back wall or more relaxed bass response

Audience Mode: -3 dB -- for off-axis listening; matches woofer level to room diffusion of highs

Tweeter/midrange level setting from normal to -6 dB

ESL panels

Two identical panels in each speaker, mounted in a barometrically isolated sub-enclosure

Vertical array; 18 cm wide x 40 cm high (7"W x 16"H)

Protected by an acoustically transparent barrier

520 square cm [80 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

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
