  • PEI tweeter dome provides smooth treble without harshness

HERTZ UNO K-170 component system

The HERTZ UNO Series K-170 is a 6.75-inch two-way component speaker system designed for listeners who want separate woofer and tweeter placement. It suits car-audio builders upgrading factory locations with a dedicated crossover network. Buyers needing a single-point coaxial drop-in or a powered subwoofer enclosure should look elsewhere.

Ferrite woofer with neodymium tweeter

The woofer uses a ferrite magnet paired with a water-repellent pressed-paper cone for mid-bass duties. The tweeter employs a neodymium magnet and a PEI dome to handle high frequencies. This magnet combination defines the system's tonal balance and installation depth.

170 watts peak handling

The system is rated at 170 watts peak power, giving headroom for dynamic musical passages at moderate listening levels. It runs out of clean output when driven continuously at high volume in large cabins or when paired with an amplifier exceeding the thermal limits of the voice coils.

Questions about this item

How does the 170 W power rating translate to actual volume and headroom in a car door installation?

The 170 W rating shows the maximum power the two-way system can handle continuously, giving strong output and clean headroom for dynamic music peaks when driven by a matching amplifier.

What crossover topology is used between the ferrite woofer and neodymium tweeter, and where does it set the transition?

A passive crossover network splits the signal between the ferrite-magnet woofer and neodymium-magnet tweeter, routing lows to the water-repellent pressed-paper cone and highs to the PEI dome.

What mounting depth and cut-out diameter does the 6.75" woofer need for a standard door panel?

The 6.75" woofer requires a matching cut-out and enough depth behind the panel for its ferrite magnet structure; the tweeter mounts separately with its own surface or flush kit.
