FOCAL 3 KM | 3″ (80 mm) Mid-Range Driver – K2 Power M Series- 3 KM

Performance Meets Precision in Compact Form The 3 KM is a specialised 3-inch (80 mm) mid-range driver built for serious car audio systems that demand clarity and fidelity in tight installation spaces. As part of the K2 Power M series, it brings Focal’s premium acoustic technologies into a compact format Key Features & Specifications Aramid fibre K2 sandwich cone with M-profile – improved frequency response, better dispersion and reduced depth Patented TMD® (Tuned Mass Damper) surround – lowered distortion and improved cone stability. Rigid aluminium non-magnetic frame – high mechanical integrity. Nominal power: ~60 W RMS, peak ~120 W (various sources). Sensitivity: ~89 dB (2.83 V/1 m) with 4 Ω impedance. Frequency response: approx. 200 Hz–9 kHz (as a dedicated mid-range driver). Mounting depth: approx. 27.3 mm / 1-1/8″. 4 Ω nominal impedance Why Use It? If you’re building a custom high-fidelity car audio system, the 3 KM allows precise mid-range reproduction with high accuracy. Its compact size makes it suitable for limited spaces while maintaining premium acoustic performance. The use of the “M” profile cone ensures better dispersion and reduced installation depth — ideal for demanding installs. Installation & System Considerations Because this is a dedicated mid-range driver, you’ll need appropriate crossover filters (often active crossovers) to ensure proper integration with tweeters and woofers. Its compact depth (~27 mm) allows for flush or near-flush mounting in constrained spaces. Should be paired with other components from the K2 Power M line to maintain tonal match and performance (e.g., 6.5 KM woofer, FRAK tweeter). Ensure your amplifier and system power levels align with the RMS/peak specs to avoid under- or over-driving. Summary The Focal 3 KM mid-range driver brings audiophile-grade mid-range clarity into a compact form, leveraging top-tier technologies like the K2 sandwich cone, TMD surround, and M-profile design. If you’re seeking to elevate your car audio build with precision and performance — this is a strong choice.
