JBL Stage3 427F

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. Our rigorous OEM-level reliability testing provides peace of mind when it’s time to crank it up for that inimitable JBL adrenalin surge.

Plus One™ Woofers Cones

Harman’s patented (US patent #7,548,631) Plus One™ polypropylene woofer cones provide increased cone area of 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 upgrade to a factory system and also for a pure aftermarket system with outboard amplification.

Edge-driven dome tweeter

Edge-drive dome tweeters on 6-1/2″ component system and 6″x9″ 3 way speakers deliver broader and smoother high frequency response.

Engineered to Fit.

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

External Crossover with 0/+3dB Tweeter level control

The Stage3 6-1/2″ component systems 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.

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 by wicking heat way from the motor structure almost like a fan as the cone moves through its stroke. The benefits are lower distortion at high output levels, a longer lasting speaker 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 extensive development process undertaken by some of the best transducer engineers in the world to provide the finest listening experience at any price point.
