JBL LS Series - Manual (Page 5)

SHOUTS AND WHISPERS:
THE LS EXPERIENCE.
The ideal home audio system doesn’t favor music over movies, or small rooms over larger ones. The ideal home audio system has the raw power to
reproduce bass and midrange frequencies without any effort or distortion at any listening level, as well as the finesse to deliver brilliantly clean high-
and ultrahigh-frequency sound directly to your ears, undiminished by interaction with walls and furniture.
In the high frequencies, LS Series speakers employ a constant-directivity HF compression driver and UHF ring tweeter in a unique computer-optimized
baffle that suppresses phase interference and signal loss. The realism of low-frequency sound is heightened with high-performance dual pulp-cone
woofers in a staggered network design for exceptionally rich bass response. Working together, these technologies ensure that LS Series speakers
render “out-of-this-world” action sequences and delicate, otherworldly musical passages with equal clarity and accuracy.
Music and movies are made to be enjoyed, and LS Series speakers are engineered to ensure that you’ll enjoy them to their fullest, whatever your
taste in entertainment may be.
60 YEARS OF BREAKING NEW GROUND: THE LS TECHNOLOGIES.
THE BI-RADIAL
HORN.
The proven design of
the proprietary JBL Bi-Radial horn
delivers precise imaging with
strict directivity for highly realistic
on- and off-axis response to 40kHz.
The graceful curves of the LS horn
baffle maximize clarity by
preventing any interference
between the HF and UHF drivers.
THE UHF RING
TWEETER.
The 015M ring
tweeter features an exceedingly
fast, highly rigid 19mm polyimide
diaphragm driven by a ferrofluid-
cooled neodymium magnet that
provides outstanding heat
resistance. The tweeter’s
diaphragm, surround and
voice-coil superstructure is
molded as a single piece to
minimize signal loss. An
oval-shaped short horn and
bullet-shaped center equalizer
control energy attenuation
caused by phase interference,
for smoother overall response.
THE HF
COMPRESSION
DRIVER.
An expressive
176Nd compression driver with
a 50mm titanium diaphragm and
lightweight aluminum voice coil
delivers superior high-frequency
response, and a ferrofluid-
injected neodymium magnet
structure provides improved
power-handling capability.
THE PURE PULP-
CONE WOOFERS.
Dual pure-pulp-cone woofers
provide exceptionally rich, realistic
bass and mid-bass reproduction.
A heat-resistant, high-excursion
Kapton
® voice coil with center-pole
vent minimizes distortion and power
compression at high output levels,
even over extended periods.
THE CROSSOVER
NETWORK.
In LS80
and LS60 speakers, a staggered
network design divides bass and
mid-bass frequencies between
identical woofers, enhancing
low-end response and smoothing
the transition to the HF driver.
The networks employ three
types of capacitors, including a
polypropylene film capacitor, for
detailed musical expression and
dynamics. Gold-plated HF and LF
binding posts allow for bi-wiring.
