JBL Synthesis 1400 Array Floorstanding Loudspeaker

Raising the Standard for Ultrahigh-end Luxury Audio

The JBL Synthesis 1400 ARRAY is a three-way floorstanding design featuring the LE14H-3 350mm (14″) Aquaplas-treated pulp cone driver with 100mm (4″) copper voice coil, the 045Ti 25mm (1″) pure- titanium compression driver and the 435AL-1 75mm (3″) Aquaplas treated aluminum-dome compression driver.

A new level of dimensional accuracy and tonal and dynamic realism

All three JBL Synthesis Project Array floorstanding loudspeakers employ advanced Aquaplas-treated high-frequency transducers and titanium-diaphragm ultrahigh-frequency drivers in an extremely dense and rigid freestanding horn.

The unconventional look of the horn assembly produces an equally unconventional sound: brilliantly clean highs – into the ethereal realm of 40kHz – delivered directly to a listener’s ears. Coupled with a fast mid- to high-frequency compression driver in the time–honored JBL Professional tradition, Project Array brings a new level of dimensional accuracy to the tonal and dynamic realism JBL is justly famous for.

Project Array loudspeakers are professional designs optimized to create a home theater to please the most demanding Hollywood director or composer. If movies are an important part of your life, you’ll appreciate the difference. More important, you’ll enjoy the professionally inspired, audiophile-grade sound on a daily basis.

Constant-directivity horns deliver massive yet highly accurate sound

Combining our proprietary horn systems with a fast bass driver in the time-honored JBL Professional tradition, Project Array brings a new level of dimensional accuracy to the tonal and dynamic realism JBL is justly famous for. Project Array is the latest innovation from Greg Timbers, JBL’s chief systems engineer, who has been behind many acclaimed and award-winning loudspeakers over the years, including the 43 Series monitors and Project K2.

Aluminum compression driver

The neodymium motor and edge-wound voice coil of Kapton®-encapsulated aluminum wire drive a 75mm (3″) Aquaplas-treated aluminum dome mounted in a rigid, constant-directivity horn. This is the secret behind the threedimensional
imaging of JBL Project Array.

Titanium super tweeter

The edge-wound voice coil attached directly to a 25mm (1″) titanium diaphragm and driven by a 50mm (2″) neodymium motor assembly delivers uniform response out to 40kHz. The vertical SonoGlass constant directivity horn maintains an optimum dispersion pattern of 60 degrees x 30 degrees.

Classic JBL bass drivers

The Project Array woofers are all based on acclaimed JBL Professional bass drivers.
They employ massive ferrite motor assemblies, edge-wound copper voice coils and
durable rubber surrounds to drive an essentially inert Aquaplas-coated pulp-cone assembly. Built to play loud and long, they proudly reflect their professional heritage.

Unique enclosure

The trapezoidal low-frequency internal enclosure is constructed of heavily braced 1-1/2″ MDF. A raised-top cavity minimizes diffraction from the exposed high-frequency horn. Brass spikes couple the external enclosure to the floor. Project Array lives up to JBL’s longstanding reputation for rugged construction.
All Array loudspeakers are available in the same rich, luxurious black zebrawood finish as the K2 S9800 Special Edition.

Seamless system integration 

Project Array crossovers use 4th-order acoustic transitions, ultralow-loss inductors
and polypropylene capacitors. The high and ultrahigh crossover sections are isolated on a separate board in a different section of the enclosure to minimize crosstalk with the low-frequency crossover.
