Dual 12-Inch Sealed Enclosure

The MTX TNE212D Terminator enclosure houses two 12-inch subwoofers in a sealed 5/8-inch MDF cabinet finished with aviation-grade carpet. It delivers 400 watts RMS and 1,200 watts peak power with a 2-ohm impedance load. The frequency response spans 37 Hz to 150 Hz for deep, controlled bass reproduction.

Ideal For Compact High-Output Builds

This enclosure suits owners who want strong low-frequency impact from a single pre-tuned box that fits in most trunks or cargo areas. Buyers needing ported output for maximum SPL or those with very limited mounting depth should consider alternative designs.

Handles Daily High-Volume Listening

The 400-watt RMS rating comfortably supports extended playback at high volumes without thermal compression thanks to Spider Plateau Venting. Peak headroom reaches 1,200 watts for dynamic transients, while the sealed alignment maintains tight cone control down to 37 Hz. Output diminishes rapidly below the tuned low-frequency limit.

Questions about this item

What amplifier power rating matches the 400W RMS of this enclosure?

An amplifier delivering around 400W RMS at 2 ohms will drive the dual 12-inch woofers to their rated continuous output without overloading them.

Will the 2-ohm impedance work with my older 4-ohm stable amplifier?

Most older amplifiers rated only for 4 ohms cannot safely drive a 2-ohm load; check your amp's minimum impedance specification before connecting this enclosure.

How do I verify the enclosure is reproducing the 37 Hz lower limit after installation?

Play a 37 Hz test tone at moderate volume; the sealed MDF box should produce clean, audible output without port noise or mechanical rattling from the carpeted panels.
