Hertz Cento CK 165 - 16.5 cm 2-Way Front System with Precise Treble and Powerful Mid-Bass
The Hertz Cento CK 165 is a 2-way component system for the vehicle front, delivering clean highs, present mids, and controlled mid-bass. At its core are the C 26 tweeter with a 26 mm Tetolon dome and 20 mm voice coil, and the C 165 mid-woofer with an SPP-M membrane. Ultra-compact CCX 2 crossovers, a balanced frequency response – even off-axis – and practical tweeter level adjustment ensure a harmonious setup for everyday use.
Technical Highlights
- 26 mm Tetolon dome (C 26) with 20 mm voice coil for natural, detailed highs
- 165 mm SPP-M (semi-pressed paper with mica) mid-woofer (C 165) for a good balance of lightness and damping
- Passive 2-way setup with 12 dB/oct. crossover at 2.5 kHz (CCX 2)
- Tweeter level adjustable via switch (0, +3 dB)
- RMS 95 W, Peak 285 W, 4 Ohm, 93 dB SPL
- Frequency response 55 Hz – 22.5 kHz
- Compact crossovers and protective grilles included
