Eminence

Eminence Neodymium 3012LF 12-in car subwoofer

SKU CH-AY7W-0H70N

12-inch car subwoofer rated at 450 W RMS with a neodymium magnet, 8-ohm impedance and 95.5 dB sensitivity

  • High output with 450 W RMS and 900 W program power
  • Deep bass extension down to 37 Hz resonant frequency
  • High sensitivity of 95.5 dB for efficient performance
  • Neodymium magnet reduces weight to 11 oz for easier installation
  • Long 9.1 mm linear excursion enables high displacement

Neodymium 12-inch Car Subwoofer

The Eminence Neodymium 3012LF is a 12-inch car subwoofer built with a neodymium magnet structure. It handles 450 W RMS and 900 W music program power at 8 ohms nominal impedance. The driver suits sealed enclosures from 23 to 59 litres and vented boxes from 37 to 85 litres.

Thermals Noise and Power Draw

The 3-inch voice coil and 0.365-inch gap height support the 450 W continuous rating without thermal compression in normal use. Sensitivity of 95.5 dB means high output with modest amplifier power. The neodymium motor keeps the moving mass at 72 grams for controlled cone motion.

Build Quality and Mounting Implications

A 16.7 T·m BL product and 9.1 mm Xmax deliver linear excursion within the recommended vented volume of 37 to 85 litres. The 545.4 cm² cone area moves up to 14.5 mm mechanically. Buyers needing smaller sealed boxes below 23 litres or drivers with lower resonant frequency should consider other models.

Questions about this item

How do I install the 3012LF in a sealed enclosure and what step is often missed?

Mount the 12-in driver in a sealed box of 23 to 59 liters; the step many miss is verifying the internal volume after bracing and displacement so the final air space stays inside the 0.8 to 2.1 cu. ft. window.

What maintenance or replacement will the 3012LF need over time?

The suspension and voice-coil assembly are the wear items; with 9.1 mm Xmax and 14.5 mm Xlim, long-term high-excursion use can fatigue the spider and surround, eventually requiring a recone kit.

What limit appears first when the 3012LF runs at high output for extended periods?

Thermal compression from the 3-in voice coil handling 450 W RMS typically arrives before mechanical bottom-out, raising Re and reducing sensitivity until the coil cools.
