Engineered for PRO-style high-volume performance, the MS4-4P delivers a massive 160W RMS / 80W minimum input power with 87.3dB sensitivity (1W/1m) —significantly louder and more dynamic than standard 4-inch speakers. Whether you're building a competition-grade system or just want to feel the music, these speakers bring the punch.
Featuring a pressed paper fiber cone with fabric suspension, a 25.5mm (1") voice coil with TIL/CCAW copper-clad aluminum wire, and a 9.5 oz ferrite magnet, this speaker is constructed to handle serious power while delivering clear, detailed midrange reproduction. The robust build ensures durability even under extreme playback conditions.
With a frequency response of 198Hz – 18kHz and a recommended active crossover of 200Hz, 12dB/octave, the MS4-4P excels as a dedicated midrange driver. Important: This speaker requires a high-pass filter (crossover) to block low frequencies—it is NOT a full-range speaker. When properly filtered, it delivers distortion-free, authoritative midrange that cuts through the mix like no other 4" driver.
Tuned for performance with Fs: 198Hz, Qts: 1.06, Vas: 0.6L, and Xmax: 2.0mm, these parameters give you the flexibility to design custom enclosures or integrate seamlessly into existing active systems. The 4Ω nominal impedance (3.0Ω minimum) allows for series, parallel, or mixed connection configurations to match your amplifier's capabilities.
With a mounting depth of just 53mm (2.09") and mounting diameter of 94mm (3.7"), these speakers fit most factory and custom door locations. The package includes mounting screws (8 pcs) and wiring female terminals (1 pair) for a hassle-free installation. Pro tip: Use a grommet when routing wires through metal panels to protect your investment.
