More about the product
The Hertz SV165.1 is a high-performance SPL midrange speaker designed for car audio systems that demand loud, clear sound. Built for enthusiasts who want strong output and precision, this model delivers exceptional midrange clarity while handling high power levels with ease.
The SV165.1 features a 165 mm (6.5-inch) ultra-light pressed paper cone. This material is chosen for its ability to produce natural, accurate sound while remaining lightweight for fast response. The water-repellent treatment ensures durability in automotive environments, protecting the cone from moisture and extending its lifespan.
Power handling is a key strength of the SV165.1. It is rated at 150 W RMS and 400 W peak, making it suitable for systems that require serious volume without distortion. The speaker uses a high-efficiency motor structure combined with a lightweight copper voice coil wound on a heat-resistant former. This design allows for excellent thermal stability and consistent performance even during extended high-power use.
A large ferrite magnet provides strong magnetic flux, ensuring precise control of the cone movement for accurate sound reproduction. With a sensitivity of 97 dB, the SV165.1 delivers impressive loudness even with moderate amplification, making it ideal for SPL-focused setups.
The frequency response ranges from 100 Hz to 10 kHz, covering the critical midrange frequencies where vocals and instruments sit. While it excels in this range, it does not reproduce deep bass or high treble, so pairing it with a subwoofer and tweeters is recommended for a full-range system.
Installation is straightforward thanks to its standard 6.5-inch size and robust build. The SV165.1 is optimised for open-air applications, such as door panels or custom enclosures, where maximum output is required.
The Hertz SV165.1 combines lightweight design, high power handling, and SPL performance, making it a reliable choice for anyone seeking impactful midrange sound in a car audio system.

Look out for Bankstown Sound Recommendations
The Hertz SV165.1 suits car audio enthusiasts who want strong midrange output for SPL or competition systems. It is ideal for open-air installations and works best when paired with a subwoofer and tweeters for full-range sound. Compared to entry-level speakers, it offers higher sensitivity and power handling, making it suitable for louder setups without sacrificing clarity. However, it is not designed for deep bass or high treble reproduction, so it is less suited for those seeking a standalone solution. For those focused on impactful midrange performance, this model is a solid choice.
