Hertz K 170 6.7" Two-Way Component Speaker System

The Hertz K 170 is a 6.7-inch, two-way component speaker system designed for vehicle audio upgrades where separate woofers and tweeters are preferred over coaxial speakers. It combines V 170 woofers with compact T 24 tweeters to place high frequencies more flexibly in the vehicle. The system is rated at 70 watts continuous power handling and uses a 4-ohm nominal impedance.

This component set is suited to listeners replacing factory speakers who want clearer front-stage presentation and more installation flexibility. Its separate tweeter design can help position upper-frequency output closer to ear level when the vehicle layout allows. The integrated tweeter crossover simplifies the signal path for an OEM-style upgrade.

The V 170 woofer uses a water-repellent pressed-paper cone and foam surround. Its V-Cone profile is designed to support off-axis response, which is useful when speakers are installed low in doors or other angled factory locations. A 25 mm pure-copper woofer voice coil works with a high-flux-density ferrite magnet.

The T 24 tweeter uses a 24 mm PEI dome diaphragm and a neodymium magnet. An annular acoustic lens is incorporated to support off-axis high-frequency dispersion. This arrangement is intended to maintain useful detail when the tweeters cannot be aimed directly at the listener.

With a 55 Hz to 23 kHz frequency response specification, the K 170 can serve as a front-speaker upgrade in a full-range system. It can be used from a compatible factory or aftermarket head unit, or with amplification matched appropriately to its 70-watt continuous rating. For systems seeking more low-frequency output, it can be paired with a separately selected subwoofer and amplifier.

Key Features

• Two-Way Component System: Separate woofers and tweeters allow more flexible speaker placement.
• 70W Continuous Power: Supports amplifier matching up to its stated continuous rating.
• V 170 Woofer: V-Cone profile supports response in off-axis door installations.
• PEI Dome Tweeter: Compact 24 mm diaphragm handles high-frequency reproduction.
• Integrated Tweeter Crossover: 6 dB/octave filtering is built into the tweeter wiring.
• Tweeter Mounting Accessories: Supports external or embedded tweeter mounting options.

Design & Installation

The woofer combines a water-repellent pressed-paper cone, foam surround, 25 mm pure-copper voice coil, and 80 mm high-flux-density ferrite magnet. Its DIN-size basket is protected by abrasion-resistant dust paint. The tweeter uses a PEI dome, neodymium magnet, and annular acoustic lens in a compact housing.

Confirm the vehicle's available mounting space before installation: the woofer has a 140 mm mounting opening requirement and 45 mm mounting depth specification. The tweeter can be externally mounted or embedded using the supplied mounting accessories. Connect the tweeter through its integrated crossover wiring and use a compatible 4-ohm source or amplifier.
