MTX Audio TX812 TX8 Series 12″ Subwoofer
Not for the Faint Hearted
Bring serious bass to your car audio system with the MTX Audio TX812 12-inch subwoofer. With 1800W RMS power handling, this TX8 Series subwoofer combines deep bass, powerful impact and controlled performance for listeners who want their music to make an impression.
Sharing its construction platform with the MTX RFL range, the TX812 brings substantial engineering to your next sound system upgrade. Its reinforced die-cast aluminium frame provides a rigid foundation, while the dual-spider suspension helps control cone movement. As a result, it delivers bass with both authority and definition.
The oversized 3-inch (75mm) voice coil handles the demands of a powerful audio system. In addition, a dual cooling system helps manage voice-coil temperature during demanding playback. A substantial 25mm magnet front plate further supports the motor assembly.
Meanwhile, the fibreglass cone, stitched cone-to-surround connection and oversized surround provide the robust construction needed for demanding bass reproduction. Together, these features make the TX812 a strong foundation for a system that puts low-frequency performance first.
