4 inch 2-way coaxial car speakers JBL SPKS141F, 4-inch pair, coaxial woofer + tweeter

JBL SPKS141F are 4-inch (10 cm) 2-way coaxial car speakers designed to upgrade in-vehicle audio. Each speaker combines a woofer and a tweeter in a single assembly to provide balanced mid/bass reproduction and clear high frequencies. With a compact 4" diameter and black finish, these speakers suit door or dash installations and are intended for everyday driving and music playback.

Advantages

The coaxial 2-way design integrates a dedicated tweeter with the woofer to deliver improved clarity across the frequency range compared with typical factory speakers. Rated at 25 W nominal output power and 4 ohm impedance, the speakers are compatible with most factory and aftermarket head units and small amplifiers. Sensitivity of 88 dB and a frequency response of 75–20,000 Hz provide usable output and clear highs in a compact 4" package.

Suitable for

• Replacing or upgrading factory door or dash speakers in cars
• Everyday music playback and commuting
• Compact installations where space for larger speakers is limited
