🚀 Key Features & Audio Technologies
- Plus One™ Woofer Cones: This patented polypropylene cone design expands the overall surface cone area by up to 35% compared to standard speakers. The larger cone increases overall efficiency by 2dB, resulting in deeper, punchier bass response.
- Edge-Driven Silk Dome Tweeters: Unlike harsher metal dome designs, these edge-driven silk domes handle smooth, expansive high frequencies that stay clear and non-fatiguing even at high volume thresholds.
- Vented Basket Frame Design: The rigid, ventilated speaker housing cools down the voice coils during heavy use. This structural cooling cuts down on sound distortion at peak volumes and dramatically prolongs the lifespan of the speaker.
- Extreme Environmental Testing: JBL puts the Stage3 lineup through brutal lab testing, exposing them to freezing cold, high heat, UV rays, and heavy vibrations to ensure reliable performance inside tough vehicle environments.
