Frequently Asked Questions - M71012 Memphis Audio
What is the recommended enclosure size for the Memphis Audio M71012?
For a sealed enclosure, use 0.8-1.0 cubic feet. For a ported enclosure, use 1.0-1.2 cubic feet tuned to 35 Hz. Always ensure the enclosure is built to specifications for optimal performance.
How do I wire the M71012 subwoofer?
The M71012 has a single 4-ohm voice coil, so it can be wired to a compatible amplifier at 4 ohms. For a single sub, connect the amplifier's positive to the sub's positive and negative to negative. For multiple subs, consult the amplifier's wiring diagram.
What amplifier should I use with this subwoofer?
Use a mono amplifier that delivers between 400-800 watts RMS at 4 ohms. Match the subwoofer's RMS power rating to avoid distortion or damage. Choose a reputable brand like Memphis Audio for best results.
How do I break in a new Memphis Audio M71012 subwoofer?
Play the subwoofer at low to moderate volume (50-70% of max) for 10-20 hours. Use music with varied bass frequencies. Avoid heavy clipping or distortion during break-in to ensure proper suspension loosening.
What is the impedance of the M71012?
The M71012 has a nominal impedance of 4 ohms. It is a single voice coil subwoofer, so it presents a 4-ohm load to the amplifier.
Can I use the M71012 in a home theater system?
Yes, it can be used for home theater if paired with a suitable amplifier and enclosure. Ensure the amplifier is compatible with 4-ohm loads and provides enough power. The subwoofer is designed for car audio but works in home setups with proper ventilation.
How do I clean the Memphis Audio M71012?
Gently wipe the cone and surround with a soft, dry cloth. Avoid using water or chemicals. For the basket, use a slightly damp cloth and dry immediately. Keep the subwoofer away from moisture and extreme temperatures.
Why does my M71012 subwoofer smell like burning?
A slight smell during break-in is normal. If the smell persists or is accompanied by distortion, it may indicate overpowering or clipping. Reduce the gain on your amplifier and ensure the subwoofer is not receiving more power than its RMS rating.
What is the mounting depth of the M71012?
The mounting depth is approximately 5.5 inches (140 mm). Ensure your enclosure has sufficient depth to accommodate the subwoofer without the magnet touching the back wall.
How do I troubleshoot a blown M71012 subwoofer?
Check for physical damage like a torn cone or voice coil rub. Use a multimeter to measure resistance: it should read around 3-4 ohms. If it reads infinite or zero, the voice coil is likely damaged. Overpowering or distorted input is the common cause.
