SKU CH-R0WP-DGS97

12-inch neodymium car subwoofer handling 400 W RMS with 100.5 dB sensitivity and 51 Hz to 3.5 kHz range

  • 12-inch driver moves more air for deep bass
  • 400 W RMS handles continuous high power
  • 5 dB sensitivity produces loud output with less amplifier power
  • Neodymium magnet reduces weight for easier installation
  • 51 Hz to 3.5 kHz range covers deep lows and mid-bass detail

12-inch neodymium car subwoofer

The Eminence 3012HO is a 12-inch car subwoofer rated at 400 W RMS and 800 W music program power. Its neodymium magnet structure keeps weight low while delivering 100.5 dB sensitivity. The 3-inch voice coil and 8-ohm nominal impedance suit high-output bass enclosures in mobile audio systems.

Check enclosure volume and amplifier matching

Verify that your planned enclosure falls within 28 to 76 litres for sealed designs or 41 to 110 litres for vented alignments. Ensure the amplifier can drive an 8-ohm load at the required power level and that the 52 Hz resonance aligns with your target low-frequency response. The usable range extends to 3.5 kHz.

Neodymium motor and robust suspension

The 11 oz neodymium magnet reduces mass without sacrificing BL product, rated at 15.9 T-M. A 0.365-inch gap height and 6.2 mm Xmax support controlled excursion, while the mechanical limit reaches 12.5 mm. Standard 12-inch mounting dimensions simplify installation in typical car audio boxes.

Questions about this item

Does the 3012HO come with an enclosure or wiring, or do I need to buy those separately?

The 3012HO is supplied as the raw driver only; you must provide a sealed box of 28 to 76 litres or a vented box of 41 to 110 litres plus speaker cable and mounting hardware.

Should I choose the 400 W RMS or 800 W PMPO rating when matching an amplifier?

Use the 400 W continuous power rating to size the amplifier; the 800 W figure is a music-program peak value, not a continuous rating.

What does the 100.5 dB sensitivity mean for actual output in a car?

At 1 W input the driver produces 100.5 dB SPL, so it reaches high volume with modest amplifier power, but enclosure tuning and cabin gain will shift the final in-car level.
