ISU 690 | 2-Way Component Speaker Kit (6×9” Woofer) – Focal Integration Series
High-Performance OEM Upgrade
A 2-way component speaker kit from the Integration range, designed for vehicles requiring 6×9” (152x229mm) speaker replacements. Built to enhance clarity, precision, and dynamic range, it allows drivers to upgrade their factory sound system without cutting, drilling, or modifying their vehicle interior.
Combining compact depth (83.5mm), Polyglass cone technology, and aluminium/magnesium tweeters, the ISU 690 delivers clean, balanced sound with authentic Focal detail — all in an OEM-friendly design.
Polyglass Cone – Accurate and Balanced Sound
The ISU 690’s woofer uses Focal’s Polyglass composite cone, formed by applying fine glass microbeads to a cellulose pulp base. This design achieves a perfect blend of rigidity and damping, producing natural midrange tones and deep, articulate bass.
The result is a smooth, neutral, and highly detailed sound signature, perfectly suited for both factory systems and aftermarket amplifiers.
Aluminium/Magnesium Tweeter – Adjustable Treble Precision
The kit’s inverted dome aluminium/magnesium tweeter delivers clear, extended high frequencies and superior off-axis dispersion. With its +3dB Flat/High treble adjustment, it lets you fine-tune the high-frequency response to suit your vehicle’s acoustic layout and listening preferences.
This ensures refined, distortion-free treble and an immersive soundstage throughout the cabin.
Compact, OEM-Ready Design
With a shallow 83.5mm mounting depth, the ISU 690 fits seamlessly into OEM speaker enclosures for straightforward Plug & Play installation. Its integrated filters simplify connection to factory head units or amplifiers, while the lightweight chassis ensures secure, vibration-free mounting.
Perfect for modern vehicles with limited door cavity space, it provides maximum sound performance with minimum installation effort.
Built for Long-Term Reliability
Engineered for durability, with a butyl rubber surround that ensures long-term stability and resistance to environmental stress. Every component is tested to meet Focal’s high standards for consistency and performance, guaranteeing years of dependable high-fidelity playback.
Precision design and premium materials combine to deliver reliable, musical, and distortion-free sound over time.
