The Hertz DSK170.3 delivers clear, detailed highs, good mids and surprising low‑frequency extension for its size, making it a strong upgrade over many factory speakers. They’re efficient and scale well with an external amp, but the tweeters can be very bright and some vehicles require mount/bracket modification during installation.

Based on customer reviewsHertz DSK170.3 — detailed, efficient 6.75" component set with bright, extended highs
The Hertz DSK170.3 delivers clear, detailed highs, good mids and surprising low‑frequency extension for its size, making it a strong upgrade over many factory speakers. They’re efficient and scale well with an external amp, but the tweeters can be very bright and some vehicles require mount/bracket modification during installation.
What buyers praise

- Clear mids and respectable mid‑bass for a 6.75" woofer
What to watch for
- Tweeters are frequently described as bright or harsh at higher volumes; EQ adjustment is commonly needed
Overview

The passive filters are found directly on the supplied connection cables, along with a rich array of accessories increasing the install-friendliness and installation time.
