Hertz Uno K 130 5.25" Component Speakers, 55W RMS, 4Ω, Pair

Hertz UNO K 130 is a 2-way component speaker system designed for OEM head unit upgrades where you want stronger front-stage clarity and midbass without changing the source. It combines a compact 24 mm (0.9") neodymium tweeter with a 130 mm (5") woofer to replace factory speakers while keeping installation straightforward.

The system is rated at 55W continuous (RMS) with 220W peak power handling at 4 ohms. The tweeter uses a 6 dB/oct crossover integrated on the tweeter wiring for an easy OEM-style install, and the tweeter’s annular acoustic lens is optimized for off-axis response to help maintain a stable stereo image from typical door/dash locations.
