The Plus One design adds cone area within the same frame size, boosting sensitivity and expanding low‐frequency output for richer musical character without enlarging the enclosure.
The shallow mounting depth and compact footprint support more mounting options across a wide range of vehicles, helping JBL signature sound fit where space is tight. The woofer uses acoustically damped, UV‐resistant polypropylene for clean, nonresonant performance that withstands heat and humidity in a car environment. A larger magnet improves power handling, delivering dynamic headroom at typical listening levels while remaining competitively priced.
Specified response about 55 Hz to 20 kHz with 92 dB sensitivity, 6 1/2" woofer, and a 2‐way configuration align with a balanced, detailed sound suitable for everyday driving. Full product description: The Club 64FSL lineup emphasizes more cone area in a compact package through JBL’s Plus One architecture, enabling higher efficiency and stronger bass without increasing frame size. The patented cone geometry increases overall cone area relative to standard designs, improving low-frequency output and musical character.
The rugged polypropylene cone is UV‐resistant and acoustically damped to minimize resonances in hot, humid car interiors. The larger magnet enhances motor strength for better control and power handling at typical listening levels in vehicles. The 6 1/2" woofer is paired with a suitable high-frequency driver in a 2‐way system to deliver coherent mids and smooth highs across a 55 Hz to 20 kHz range.
The shallow design supports easier installation in modern dashboards and doors, and the black finish blends with most interiors. Overall, these speakers deliver a reliable JBL upgrade with improved bass, clarity, and durability.
