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.
