Hertz K130 5.25" Two-Way Component Speaker System

The Hertz K130 is a 130 mm (5-inch class) two-way component speaker system designed for replacing factory-installed front speakers. It separates the woofer and tweeter so they can be positioned more effectively than a typical coaxial speaker. This makes it a practical option for vehicles with dedicated door-speaker and tweeter locations.

The system combines V 130 woofers with T 24 tweeters to cover bass, midrange, and high-frequency duties. Its 55 W continuous power handling and 4-ohm impedance make it suitable for use with compatible factory radios or an appropriately matched external amplifier. With 93 dB SPL sensitivity, it is designed to produce useful output without requiring unusually high amplifier power.

The V 130 woofer uses a water-repellent pressed-paper cone, foam surround, and V-cone profile. This construction is intended to support clear midrange response and bass output from a compact door-mounted driver. A 25 mm pure-copper voice coil and high-density ferrite magnet support the woofer motor assembly.

For the high frequencies, the T 24 tweeter uses a 24 mm PEI dome and neodymium magnet. Its annular acoustic lens is designed to support off-axis performance, which is useful when tweeters must be mounted away from the listener's direct line of sight. The tweeter wiring includes an integrated 6 dB/octave crossover.

The K130 is suited to an OEM-style speaker upgrade where separate tweeter placement is available or can be added. Its compact woofer dimensions and included tweeter mounting accessories support a range of installation approaches. Pair it with a properly configured head unit or amplifier, while confirming vehicle mounting depth, cutout, and wiring requirements before installation.

Key Features

• Two-Way Component Design: Separates woofer and tweeter placement for a more flexible front-stage upgrade.
• 130 mm Woofer: Fits applications designed for a 5-inch-class speaker size.
• PEI-Dome Tweeter: Uses a compact 24 mm dome for high-frequency reproduction.
• Integrated Tweeter Crossover: A 6 dB/octave filter is built into the tweeter wiring.
• Water-Repellent Paper Cone: The woofer cone material is designed for automotive-door use.
• V-Cone Woofer Profile: Supports off-axis response in typical vehicle speaker locations.

Design & Installation

The V 130 woofer uses a water-repellent pressed-paper cone, foam surround, pure-copper 25 mm voice coil, and high-density ferrite magnet. Its DIN-size basket is protected by abrasion-resistant dust paint. The T 24 tweeter combines a PEI dome, neodymium magnet, and annular acoustic lens.

Confirm that the vehicle accepts a 130 mm woofer and compare the available opening and depth with the listed 116 mm mounting opening dimension and 52 mm mounting-depth dimension. The included tweeter accessories support external or embedded mounting. Connect the tweeter through its integrated crossover wiring, and use an amplifier or radio compatible with a 4-ohm speaker load.
