JBL Stage3 48
The JBL Stage3 48 car speakers are two-way coaxial drivers for your car's sound system. The patented Plus One diaphragm architecture, with a larger cone area, results in higher sensitivity and more powerful bass. With a continuous power of 50W RMS, they are compatible with both a head unit and an external amplifier, and cover a frequency spectrum from 80Hz to 20kHz.

Patented diaphragm for more powerful bass
The woofer cone diaphragm has a patented Plus One architecture. This provides a larger overall cone area compared to similar speakers, delivering higher sensitivity and a stronger low-frequency response. The diaphragm contains 10% glass fibre. Its surface is also shaped by a laser-engraved mould, which creates a visual effect similar to forged carbon fibre.
Clear highs and optimised performance
The balanced PEI dome tweeter delivers clean high-frequency reproduction. Its design ensures a smooth and wide frequency response without unwanted harshness at any volume level. The speakers operate with a true 4-ohm impedance, which compensates for resistance in the system, maximising the output power from the head unit or connected external amplifier.
