12-inch dual voice coil subwoofer

The MTX Terminator TN12-04 is a 12-inch car subwoofer with a dual 4-ohm voice coil, rated for 200 watts RMS and 400 watts peak power. It targets drivers who want deeper bass from a single woofer without moving to a multi-subwoofer installation. The polypropylene cone and rubber surround are built for durability in automotive environments.

Sustained output with thermal management

Spider Plateau Venting directs airflow at the 1.50-inch voice coil to reduce heat buildup during extended play, while the Asymmetrical Linear Drive System uses a flat progressive spider and extended pole piece to keep cone motion linear at higher excursions. The 86.4 dB sensitivity and 24 Hz to 160 Hz frequency response are maintained across longer listening sessions rather than only during brief peaks.

Upgrade from a single voice coil or smaller woofer

This model replaces a single voice coil 12-inch subwoofer by adding wiring flexibility for 2-ohm or 8-ohm amplifier loads, and it supersedes 10-inch units when the sealed 1.25 cu ft or ported 2.00 cu ft enclosure volumes fit the vehicle. The jump is worth it when the installer can supply 100 to 200 watts RMS and accommodate the 5.44-inch mounting depth and 11.08-inch cut-out diameter.

Questions about this item

Does the 86.4 dB sensitivity and 200 W RMS rating mean the subwoofer runs hot during long sessions?

The 86.4 dB sensitivity means the subwoofer produces high output with less amplifier power, reducing heat buildup at the 1.50" voice coil during extended use.

What amplifier power range is required to drive the 4 Ω dual voice coil at 200 W RMS?

An amplifier delivering 100 to 200 W RMS into a 4 Ω load is recommended to match the subwoofer's 200 W RMS rating and dual voice coil configuration.

Will the 5.44" mounting depth and 11.08" cut-out fit the same enclosure I used for my old 12" sub?

The 5.44" mounting depth and 11.08" cut-out diameter are specific to this model; compare those figures with your existing enclosure before installing.
