20
Intimate B: 0 dB -- for speaker placement near back wall or
more relaxed bass response
o
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
o
Two identical panels in each speaker, mounted in a barometrically
isolated sub-enclosure
o
Vertical array; 18 cm wide x 40 cm high (7"W x 16"H)
o
Protected by an acoustically transparent barrier
o
520 square cm [80 square inch] forward radiating area per array
o
Tough, stable, injection molded, ABS stator frames
o
66-element, parallel wire, stator electrodes (total of 132 electrode
elements per panel)
o
Unique panel construction and materials are immune to the effects
of wide and rapid temperature and humidity swings
o
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
•
Woofers
o
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
o
Operate far below their breakup frequencies and their Xmax for
practically no cone coloration
o
Seamless acoustical integration with the ESL
o
Strong, accurate bass, not boomy dance club bass
o
Exceptionally low series resistance in crossover conserves damping
factor and maximizes cone control
•
Enclosure
o
Sealed (acoustic suspension) for best woofer transient response,
minimal group delay, and best integration with ESL array
o
High mass, 25 mm [1”] thick, well damped wall materials for
negligible enclosure radiation
o
63 mm [2.5"] thick, solid hardwood baffle is maximally stable and
rigid, yet free of resonances
