## Features

- DIMENSIONS AND COMPACT DESIGN The X 690 features a DIN basket design that makes installation easy even in confined spaces or complex configurations. The low installation depth and compact 4-way system structure allow easy integration into OEM 6x9 systems, providing an ideal solution for installers and planners who need a high-performance product without compromising space.
- PERFORMANCE AND SOUND QUALITY With a durable 340W power output and a 25mm pure copper coil woofer, the X 690 ensures high dynamic control and precise sound reproduction. The frequency response extends beyond 20 kHz thanks to the double designed 15 mm piezoelectric super tweeter, while the high sensitivity and low harmonic distortion allow SPL performance at a high level that ensures clarity and detail even at high volumes.
- Materials and workmanship quality: the membrane made of high-strength press paper is water-repellent treated and finished with a grey metallic paint, which offers an optimal ratio of lightweight and mechanical stability. The 80mm high flux density ferrite magnet combined with the 25mm pure copper coil contributes to distortion-free acoustic behavior, while the foam surround allows for extended and controlled bass response.
- Easy installation and versatility: the system is designed for quick integration into OEM systems thanks to the DIN basket and the abrasion-resistant dust cover. The optimized front panel layout with tweeter and super tweeter improves off-axis performance, extends positioning capabilities without sacrificing acoustic degradation, and supports flexible configuration that adapts to different vehicle layouts.
- Brand value Hertz is a brand that stands for reliability and innovation in the professional audio sector and has a long tradition in research and technological development. The X 690 embodies the experience gained over years of advanced development, integrating proprietary solutions such as the dual-engineered piezoelectric super tweeter and selected materials, confirming the brand's reputation as a reference for demanding installers and audiophiles.
