Hertz Cento Pro CPX 690 - 6x9 Inch 3-Way Coaxial Speakers for Powerful Sound
The Hertz Cento Pro CPX 690 is a 3-way 6x9-inch coaxial speaker that provides powerful bass and clear highs in vehicle rear decks and door systems. Its design, featuring neodymium tweeters and supertweeters with Tetolon domes, delivers detailed mids/highs, while the woofer with a water-repellent paper cone ensures solid bass performance. The Radial Venting System improves voice coil cooling and stabilizes performance even at higher levels. A durable ABS and metal protective grille is pre-installed, protecting the cone in everyday use.
At Carhifi.shop, you'll find the CPX 690 for direct OEM replacement or as an upgrade in 6x9-inch mounting locations.
