Ultimate Car Audio by JBL
JBL Stage3 speakers bring patented technologies, world-class engineering and JBL pro sound heritage together to create a powerful line of car audio loudspeakers. Focusing on performance and fitment, they bring unrivaled sound performance to your vehicle. The high output 2 ohm DCR design extracts every watt of power from the amplifier or head unit enabling the patented Plus One woofers to deliver high output and solid deep bass performance.

Engineered to Fit
Close attention to fitment is paramount to the success of this speaker family.

Edge-driven Dome Tweeter
Edge-drive dome tweeters on 6.5" component system and 6"x9" 3way speakers deliver broader and smoother high frequency response.

External Crossover with 0/+3dB Tweeter Level Control
The Stage3 system feature external crossovers to precisely manage frequency distribution between the mic-woofer and tweeter. To allow for further system tuning, a 0/+3dB tweeter level control has been providing allow for adjustment based on tweeter location.

Plus One Woofer Cones
Harman's Patented (US patent No.7548631) Plus One cones provide increased cone area up to 35% by moving the attachment point between the surround and the frame outward. The benefit of this technology is an increase in overall efficiency by up to 2dB. This provides superior output and performance when used as an ipgrade to a factory system and also for a pure afthermarket system with outboard amplification.

Vented Basket Frame Design
The super-rigid vented baskets help to cool the voice coils making for a reliable speaker.Not only do these look cool but they provide a real world benefit bt wicking heat way from the motor structure almost like a fan ad the cone moves through its stroke. The benefits are lower distortion at high output levels, a longer lasting sepaker and higher power handling.

Competitively Tuned
For most brands, off-the-shelf speakers and a cursory approval of frequency response curves are good enough. That's not the case with JBL. We Don't only listen to our speakers against the competition - we voice them against each other to ensure each line has the consistent JBL sound signature that's known and sought out by those who care about their audio. This is just part of an ectensive development process undertaken by some of the best transducer engineers in the world to provide the finest listening experience at any price point.
