GTO SPEAKERS

GRAND TOURING

®

 SERIES

For more than 60 years, JBL has been delivering

products embodying the technology developed

in the professional arena – equipping leading

recording studios and movie theaters, as well as

live-music reinforcement in venues ranging from

dance clubs to Woodstock. We continue to

transform this expertise into products that

provide the impact and excitement of a live

performance. The JBL

®

experience is for

enthusiasts who won’t settle for anything 

less than “live” at home or on the go. 

PLUS ONE

®

WOOFER CONES

Each GTO model uses a patent-pending woofer

cone with more surface area than in competing

models of the same size. The benefits are

increased bass output and increased efficiency,

both very audible and important. 

REDUCED NOMINAL

IMPEDANCE

That’s right – GTO speakers have 2-ohm voice

coils. This enables them to extract all the power

from amplifiers and head units that are designed

to increase power when driving 2-ohm loads.

LOW-Q WOOFER DESIGN

The lower Q offers higher bass output and better

transient response in typical mounting locations

(doors, rear package trays).

UNIPIVOT

TWEETER POD

Select JBL GTO models use a unique, patented

rotating-tweeter design, which allows the

installer or end user to aim the tweeter toward 

the sweet spot for optimal imaging.

INTERMOUNT III

†

MOUNTING SYSTEM

Allows for installation of all 6-1/2" models in 

all four 6"-hole size standards without the need

for additional adapters or installation kits.

BUILT-IN CROSSOVER

NETWORKS

Most JBL GTO speaker models come with

integrated high- and low-pass filters. This 

results in a smoother transition between the

woofer and tweeter, delivering superior 

midrange performance.

ADVANCED ENGINEERING

The JBL GTO speaker lineup is the result of real

engineering and real-world testing. This results in

speakers that absolutely sound better than the

competition. High output, better bass response,

long life and a smooth response are what you can

expect from a GTO speaker, or any other speaker

that wears the JBL badge.
