Hertz CK165L 6.5" 2-Way Component Speaker System

The Hertz CK165L is a 6.5-inch, 2-way component speaker system designed for vehicle audio upgrades where separate woofers and tweeters are preferred over factory full-range speakers. Its 4-ohm design suits many aftermarket amplifiers and compatible factory-replacement installations. The system pairs C 165 L woofers with C 26 dome tweeters and dedicated passive crossover networks.

This kit is intended for listeners seeking a more defined front soundstage, with bass and midrange handled by door-mounted woofers and high frequencies placed separately. The 165 mm woofers use non-pressed paper cones to provide controlled low-frequency response. A 26 mm Tetolon fiber tweeter supports detailed upper-frequency reproduction.

The CK165L is rated for 100 watts continuous power handling and 300 watts peak power handling. Its complete system frequency response is specified at 50 Hz to 22.5 kHz. Woofer sensitivity is rated at 91 dB SPL, while tweeter sensitivity is rated at 92 dB SPL.

Hertz uses a high-density-flux ferrite motor with low-carbon polar plates on the C 165 L woofer. Its 25 mm voice coil is wound on an aluminum former and is designed for extended excursion. The woofer also uses a three-spoke basket and rubber magnet cover to help control unwanted mechanical vibration.

Separate CCX 2W and CCX 2T crossovers simplify placement compared with a single large network. The woofer network uses a 6 dB-per-octave low-pass section, while the tweeter network uses a 12 dB-per-octave high-pass section. This makes the CK165L a practical component-system upgrade for installations with suitable door locations, tweeter locations, and amplifier or receiver power.

Key Features

• 2-Way Component System: Separate woofers, tweeters, and crossovers support flexible speaker placement.
• Non-Pressed Paper Woofer Cone: Helps deliver natural midrange and controlled low frequencies.
• Tetolon Dome Tweeter: Soft 26 mm dome reproduces detailed high frequencies.
• Separate Passive Crossovers: Compact woofer and tweeter filters simplify system routing.
• Selectable Tweeter Level: Choose 0 dB or +3 dB treble attenuation.
• Protective Grilles Included: Supplied ABS grilles add protection for exposed woofer installations.

Design & Installation

The C 165 L woofer combines a water-repellent non-pressed paper cone, high-density-flux ferrite magnet, low-carbon polar plates, and a 25 mm aluminum-former voice coil. The C 26 tweeter uses a Tetolon fiber dome and neodymium magnet. Hertz also supplies high-resistance ABS grilles with a metallic finish and removable metal mesh.

Confirm available door-panel clearance and mounting opening dimensions before purchase. The woofer requires a 142 mm mounting hole and 62.5 mm mounting depth, while the C 26 tweeter supports OEM, flush, or angled mounting approaches with its installation accessories. Connect the amplifier or head-unit speaker output to the separate crossover inputs, then route each crossover output only to its designated woofer or tweeter.
