JBL LS Series Speaker Systems

Building on the Legacy, Setting a Higher Standard.

An Advanced New Expression of the Most Advanced JBL Technologies

JBL has been a hallmark in loud, clear, and stunningly realistic audio reproduction for public spaces and private homes for over 60 years. This distinction is achieved by utilizing innovative technologies and materials across their product lines, bringing JBL Pro Sound Home™.

Introducing the LS Series, a new line of high-performance loudspeakers that share the design philosophy and signature Bi-Radial® horn/compression-driver configuration of acclaimed JBL Project speakers like K2® and Array, as well as the Everest DD66000. The LS Series was designed to deliver greatness, offering an uncannily lifelike musical instrument experience.

Advanced Engineering Meets Exquisite Craftsmanship

The LS enclosures are designed not only for aesthetic appeal but also for superior acoustic performance. The wedge shape and gently curving side panels prevent unwanted internal resonance. High-mass MDF construction minimizes sound coloration. A curved lower baffle prevents acoustic interference with the lower woofer, gracefully transitioning into gloss-finish, streak-ebony side panels with a rich mahogany shade.

Shouts and Whispers: The LS Experience

The ideal home audio system reproduces bass and midrange frequencies effortlessly and without distortion, while delivering brilliantly clean high- and ultrahigh-frequency sound directly to the listener. The LS Series achieves this through advanced technologies:

Key Technologies:

The Bi-Radial® Horn: Delivers precise imaging with strict directivity for realistic on- and off-axis response up to 40kHz. Its graceful curves maximize clarity by preventing interference between HF and UHF drivers.
The UHF Ring Tweeter: Features a fast, rigid 19mm polyimide diaphragm driven by a ferrofluid-cooled neodymium magnet for outstanding heat resistance. The single-piece molded diaphragm, surround, and voice-coil superstructure minimize signal loss. An oval-shaped short horn and bullet-shaped center equalizer control energy attenuation for smoother overall response.
The HF Compression Driver: An expressive 176Nd compression driver with a 50mm titanium diaphragm and lightweight aluminum voice coil provides superior high-frequency response. A ferrofluid-injected neodymium magnet structure enhances power-handling capability.
The Pure Pulp-Cone Woofers: Dual pure-pulp-cone woofers deliver 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.
The Crossover Network: In LS80 and LS60 speakers, a staggered network design enhances low-end response and smooths the transition to the HF driver. It utilizes three types of capacitors, including a polypropylene film capacitor, for detailed musical expression and dynamics. Gold-plated binding posts allow for bi-wiring.

These technologies ensure that LS Series speakers render action sequences and musical passages with equal clarity and accuracy, making music and movies more enjoyable.

A 60-Year Love Affair with Movies and Music

JBL's history is deeply intertwined with the evolution of sound in entertainment:

1940s: James B. Lansing founded JBL, striking out on his own after leading the team that first brought sound to movies. Early products included a high-frequency transducer still used today.
1950s: JBL became the choice for studio and theater sound. Leo Fender chose the JBL D130 transducer for his electric guitar. The Hartsfield speaker introduced high fidelity to homes.
1960s: The legendary 4320 speaker became the definitive studio monitor. JBL equipment became standard at rock concerts worldwide.
1970s: JBL studio monitors were ranked Number One by Billboard magazine. The L100, a consumer version of the 4320, brought JBL Pro technology home and became a bestseller.
1980s: JBL components were chosen for 70mm Dolby® stereo in showcase theaters. Titanium diaphragms and Bi-Radial horns were introduced in professional monitors.
1990s: THX® theater installations were dominated by JBL speakers. Near-field studio monitors led in 5.1 and 7.1 sound mixing. The JBL Simply Cinema system, an early "one box" home theater solution, was introduced.
Today: The JBL LS Series loudspeakers utilize classic high-end JBL technologies to bring breathtaking new life and depth to home entertainment.

The Architects

The LS Series is the result of a collaboration between JBL systems engineer Charles Sprinkle and Daniel Ashcraft, chief creative officer of Ashcraft Design. Sprinkle, an audio enthusiast, contributed to several innovative JBL systems, including JBL Cinema Vision™, Venue®, JBL Cinema Sound, and JBL Control NOW™. For the LS Series, he developed improved horn designs and new low-frequency transducers for acoustical integration.

Daniel Ashcraft, with over 20 years of experience in JBL industrial design, co-developed legendary systems like the JBL Project Everest DD55000 and Project K2 S9500, along with their successors. Together, Sprinkle and Ashcraft created a visually stunning loudspeaker system with exceptionally lifelike, effortless sound.
