KEY MESSAGES

PERFORMANCE

High output 3-way enclosure featuring the D2 Dual Diaphragm

Dual Voice Coil high-frequency compression driver in a lightweight trapezoidal enclosure.

JBL TRANSDUCERS

Differential Drive™, Dual Neodymium Magnet, Dual Voice Coil,

Direct Cooled™ MF and LF cone transducers.

The VTX F35 was designed to address a wide range of applications where high-impact, high-fidelity audio needs to be delivered with the

form factor of a trapezoidal full-range system. The F35 is the go-to choice for customers needing high-power side-fills, mains speakers,

or a high-performance point-source solution to complement to larger VTX system systems. This system has an exceptional power-toweight ratio thanks to its lightweight, Differential Drive 15” and 8” transducers, and benefits from proven JBL technologies, including

a multi-band Progressive Transition Waveguide and the high-performance D2 high-frequency driver. The F35 ships with a detachable

front-face dolly-board as standard and it is available in 60x40 or 90x50 coverage patterns. The cabinet is equally suitable for stackable

and suspendable configurations thanks to the integrated M10 mounting points. The F35 is acoustically compatible with all other VTX

Series systems, and it’s truly a flexible design that delivers uncompromising performance in a compact package.

PROGRESSIVE TRANSITION™ (PT) WAVEGUIDES

The F35 Progressive Transition Waveguides provide excellent coverage control and are rotatable so the loudspeaker system can be used

in either the vertical or horizontal orientation. The distinctive feature

of PT Waveguides is the lack of a traditional diffraction slot. Instead,

the sidewalls transition smoothly from the driver’s throat through to

the rectangular mounting flange. This translates to optimal frequency

response superbly low distortion. The beamwidth and directivity are

optimal in the horizontal plane while the vertical beamwidth was optimized to match with F35 low frequency and midrange transducers.

DIFFERENTIAL DRIVE® TRANSDUCERS

Differential Drive transducers are using a creative reconfiguration of the basic elements of the low-frequency driver. Heat

sinks are integrated into the driver’s cast aluminum frame, and

the neodymium magnets are placed inside the driver’s dual

voice coil assembly, completing the magnetic circuit without

the heavy surrounding steel structure of conventional drivers.

While dramatically reducing driver weight, all critical performance parameters are greatly enhanced: frequency response,

power output and distortion. The resulting sound quality is extraordinarily transparent, even at very high SPL, while system

weight and physical footprint can be reduced by as much as

half when compared to conventional speaker systems. JBL’s

Differential Drive technology is now at the core of all VTX Series loudspeakers from the large format Line Arrays to the VTX

F35 and compact stage monitors.

4-CHANNEL, 3-WAY DESIGN

The VTX F35 features a full 3-way design and utilizing 4-channels of

amplification and DSP. The F35 was design to work best with Crown

Audio I-Tech 4x3500HD amplifier and up to three cabinets can be

connected to one amplifier.

VERSATILE

Multiple M10 attachment points facilitate a variety of suspension

options. Rotatable mid-hi waveguide for use in either vertical or

horizontal orientation. Included front-face dolly for easy transportation.

JBL GC2

Dual 18-Inch High Performance Subwoofer

JBL GC2 dual 18-inch subwoofer features two 18-inch

transducers compared to traditional single-coil designs. The

transducers use Differential Drive®

technology, which provides

better heat dissipation, lower power compression and higher

dynamic range. In addition, the magnetic saturation pole piece

and aluminum shorting ring signiicantly reduce non-linear

distortion.

The transducer features a patented Differential Drive®

dual

voice coil and a magnetic gap neodymium magnet cone.

JBL GC2 supports ground stacking only, with a practical shape

for easy stacking and precise cabinet volume for fast low

frequency response performance.

KEY MESSAGES 

System Solution

JBL GC2 features practical design. For example, the doublelayer feet to meet the needs of ixed installations; tilting

connector box allows it to it closely to the wall without having

to reserve space for cable installation; supports for stacking

applications, either horizontally or vertically. JBL GC2 uses two

high-powered woofer units, providing high-end low-frequency

response performance and stable characteristics.

Performance

JBL GC2 woofer features ultra-low frequency response, patented

Differential Drive®

dual voice coil and magnetic gap neodymium

magnet cone technology, designed to provide accurate ultra-low

frequency coverage to meet demanding applications.

Structure Innovations

The GC Series features a unique structural innovation that

distinguishes it from traditional single voice coil woofers by

using dual voice coil and magnetic gap neodymium magnet

cone transducer technology. The structure of the cabinet is

redeined according to the characteristics of the low-frequency

unit, reducing non-linear distortion and improving low-frequency

dynamic response.

HIGHLIGHTS 

JBL Transducers

JBL GC2 is a compact, powerful subwoofer that features two 18-inch woofer. The

woofer employs unique dual voice coil and neodymium magnets and Differential

Drive®

technology to deliver better heat dissipation, light weight, extra-long excursion,

and lower low frequency performance than conventional single-coil designs.

High Performance

JBL GC2 redeines the internal structure of the cabinet, which uses \"Baltic\" birch

wood panels to maintain lower low frequency performance and to sustain large

dynamic and high intensity output, making it ideal for top venues requiring advanced

low-frequency response.

Durable and Reliable

With more than 70 years of acoustic technology and rigorous testing standards, JBL

GC2 loudspeaker maintains the acoustic characteristics of high output and high

dynamics, but also has a durable and reliable performance.

FEATURES 

Unique and Innovative Internal Design

Compared to traditional single-coil designs, JBL GC2 use Differential Drive®

dual

voice coil technology to provide high dynamic range and low power compression with

reduced non-linear distortion. At the same time, many innovative structural designs

have been made to enhance the sound stability according to the needs of high-level

venue applications.

Flexible Installation

JBL GC2 is equipped with a round hole on the top for stacking; the innovative tilted

connector box design allows it to it closely to the wall without reserving space for cable

installation; the removable double-layer feet (rubber + plastic) design; the dynamic

appearance and double logo design can blend into high-end place applications.
