JBL Stage3 527FAM 5.25" Coaxial Speakers

40W RMS per speaker with a 3Ω load in a compact 5.25" coaxial package—the JBL Stage3 527FAM delivers high-output, deep bass and JBL-pro sound for performance-focused car audio builds.

• Power Handling: 40W rms, 200W peak — This is the continuous and peak power the driver can handle, informing how loud and dynamic your music can be without clipping during demanding passages.
• Sensitivity: 91dB @ 2.83V/1m — Higher sensitivity means more output with less input power, helping you achieve louder sound from modest amplification.
• Frequency Response: 75Hz – 20kHz — Provides bass presence down to 75 Hz and full-range treble up to 20 kHz, contributing to a cohesive front-stage image from a single component.
• Impedance: 3 ohms — Impedance affects how much current your amp must supply; a 3Ω load will draw more power than a 4Ω load, influencing amplifier pairing.
• Plus One™ Woofers: Enables high output and solid deep bass performance — Part of JBL’s patented woofer design intended to maximize bass impact in a compact speaker.
• 2 ohm DCR Design: High output design enables efficient power extraction from the amplifier or head unit — aligns with the stated aim of delivering strong performance from available audio sources.
• OEM‑Level Reliability Testing: Rigorous reliability testing provides confidence for long-term, high-use listening — designed to endure typical car audio environments.

Benefits: In a typical upgrade, these 5.25" coaxials serve as a complete front or rear category upgrade, delivering a coherent sound with integrated high-frequency response from a single mounting footprint. The 40W RMS continuous rating pairs with compatible amplifiers to reproduce dynamic tracks without clipping, while the 3Ω load and 91dB sensitivity help you match amplification for loudness and efficiency. The Plus One™ woofer technology contributes to stronger bass in a compact enclosure, and OEM-level reliability testing backs you up for real-world driving conditions.
