JBL Stadium GTO 620 User Manual

Stadium Speakers

High performance multi-element speakers and component systems engineered to deliver world-class
JBL performance and superior fi t into most factory speaker locations.

Ultimate Car Audio by JBL.

JBL – speaker of choice for the world’s top recording studios, concert
events and movie theaters, delivers a world class listening experience
to car audio with the new Stadium speakers. Unmistakably JBL. The
high output 2 ohm design extracts every watt of power from the
amplifier or head unit enabling the patented Plus One
to deliver an impressive wallop for mega volume aficionados.
Sophisticated crossovers coupled with soft dome tweeters produce
smooth as silk highs with extraordinary detail even at the highest
volume levels. An optional midrange speaker with bandpass crossover
provides seamless integration with woofer and tweeter, transforming
a two-way component system into a three-way system for another
magnitude of sound. Rigorous OEM-level reliability testing provides
peace of mind when it’s time to crank it up for that inimitable
JBL adrenalin surge.

JBL Patented Plus One™ Glass Fiber Woofers with Rubber
Surrounds

Plus One™ glass fiber woofer cones are lighter and stiffer with up
to 25 percent more active cone-area than the competition. The
result is remarkably accurate sound with high SPL performance.
The hi-roll rubber surrounds allow the woofer cone to move freely
and emit bolder bass.

High Output 2 Ohm Design

High output 2 ohm design with low impedance voice coils extracts
every watt from the amplifier, delivering peak power with ease.
Lower impedance also compensates for any added resistance in
thin factory-installed wiring.

Harman Standard Reliability Testing

JBL speakers have to go through environmental testing that would
destroy other speakers. JBL freezes them, bakes them, shakes
them, blasts them with ultraviolet light and drives them at full
power for days at a time.

Competitively Tuned

JBL employs second order filters for tweeters and sophisticated
two-way crossovers for multi-element speakers and component
systems resulting in higher power handling and added flexibility
and accuracy when tuning speakers. A higher quality crossover
allows JBL’s wizards to consider speaker acoustic characteristics
as well as specifications when tuning the JBL sound.

Stadium Speakers by JBL

The modern exterior design and premium finishes of Stadium
speakers further reflect the quality of JBL engineering. In short,
they look as good as they sound.

Oversized (35mm) Woofer Voice Coils

Oversized voice coils with extra copper and surface area serves
to dissipate the heat for improved reliability, enabling maximum
power handling with low distortion.

Edge-driven Soft Dome Tweeters

Home theater quality soft dome tweeters deliver broader and
smoother high frequency response. A push-button tweeter level
control (+0 dB flat and +3 dB) provides custom tuning of high
frequencies in most multi-element speakers.

3-way Upgradability

Crossovers on component systems are gap-switchable to
accommodate a midrange upgrade. The optional midrange includes
a bandpass crossover to convert a two-way system into a three­way system with perfect tonal balance and is designed to fit into
many factory three-way applications.
