Hertz Uno Series X 690 6×9-Inch (160×230mm) 340W 4-Way Coaxial Speakers

Deliver powerful, full-range dynamics and broad frequency response across your vehicle cabin with the Hertz Uno Series X 690 6×9-Inch 4-Way Coaxial Speakers. Engineered in Italy by Hertz to combine deep low-end punch with detailed high-frequency articulation, this high-output 4-way system utilizes an oversized pressed-paper woofer, a dedicated balanced dome tweeter, and a dual-super-tweeter array to reproduce music with clarity, impact, and wide acoustic staging.

Featuring an ultra-high sensitivity rating of 94 dB SPL, the X 690 extracts maximum acoustic output and dynamic contrast directly from factory head units or aftermarket media receivers. Its weather-treated cone, high-flux ferrite motor, and low-profile multi-driver bridge allow it to drop cleanly into standard 6×9 parcel shelves and door apertures without clearance headaches.

Key Features & Benefits:

• High-Output 4-Way Multi-Driver Array: Features a dedicated woofer, a 40mm midrange/tweeter, and two 15mm PEI dome super-tweeters to deliver clean instrument separation, natural vocal projection, and sparkling high-frequency harmonics up to 22,000 Hz.
• Exceptional 94 dB SPL Sensitivity: Remarkable acoustic efficiency allows these speakers to produce loud, punchy, distortion-free sound even when driven straight off a standard factory radio or aftermarket head unit.
• Water-Repellent Pressed-Paper Cone: Natural paper pulp construction provides snappy transient response and natural tonal timbre, treated with an anti-moisture coating to protect against condensation and temperature shifts inside vehicle cavities.
• V-Cone® Exponential Geometry: Maximizes cone rigidity while promoting wide off-axis sound dispersion throughout the cabin, ensuring listeners off-center still hear rich midrange body.
• Foam Surround with Linear Excursion: Flexible, durable foam surround allows extended linear cone travel for authoritative mid-bass impact without mechanical distortion.
• Pure Copper Voice Coil: 25 mm (1-inch) high-temperature copper voice coil wound on a Kapton former guarantees efficient heat dissipation and thermal durability during prolonged high-volume playback.
• Low Tweeter Faceplate Protrusion: Slim multi-driver bridge profile minimizes vertical clearance requirements, dropping cleanly underneath OEM factory grilles and rear parcel shelf trims.

Ideal Applications:

• Rear Parcel Shelf & Boot Decks: The ultimate acoustic drop-in upgrade for sedans, notchbacks, and coupes with factory 6×9 cutouts seeking deep bass fill and wide stereo presence without an immediate subwoofer purchase.
• Truck & Bakkie Doors: Direct replacement for vehicles equipped with factory 6×9 front or rear door openings (e.g., Toyota Hilux, Fortuner, American trucks).
• Head Unit-Powered & Amplified Installs: Highly responsive on low head unit power, yet robust enough to handle clean amplification from 2-channel or 4-channel power amplifiers.
