About the MB Quart RW1-304
MB Quart has been turning out high-quality car audio equipment for over 50 years, creating the immersive experience that listeners crave. Now they bring you their Reference Series subwoofers, made to deliver the kind of low end that captures attention inside and outside your vehicle.
The RW1-304 is a 12" component subwoofer with dual voice coils that can be wired for 2-ohm or 8-ohm impedance, giving you a wide array of system options. The non-pressed coated paper cone delivers warm bass, while the double-stitched foam surround and specially-designed spider keep the cone in check for higher power handling with minimal distortion.
Serious power handling
A heavy-gauge black powder-coated die-cast aluminum basket holds everything together with stability and style. The 3" voice coil and dual 70-ounce magnets allow this sub to handle up to 1000 watts RMS for impressive low-frequency performance. This sub will take all the power your music can dish out.

Dual 4Ω Voice Coils: The dual 4Ω voice coils offer wiring flexibility; when wired in parallel the woofer presents a 2Ω load, when wired in series the woofer presents an 8Ω load.
Terminals: The two sets of spring post terminals will accommodate single banana plugs and bare speaker wire up to 10 gauge.
Ported Enclosures: Ported (or vented) enclosures typically provide better overall efficiency than sealed, so they are suitable for use with smaller amplifiers, giving you more bass output from a given amount of power. Two ported enclosure volume options are listed in the manual:
- Best Sound Quality: 2 ft³ with one 4" diameter x 15½" long port, resulting in a tuning frequency of 28 Hz and a -3dB point of 25 Hz
- Highest SPL: 1.75 ft³ with one 6" diameter x 18" long port, resulting in a tuning frequency of 41 Hz and a -3dB point of 38 Hz
