PowerBass 3XL-1210D - 12" Dual 1-Ohm Subwoofer

PowerBass 3XL-1210D 12" Subwoofer, Dual 1-Ohm, 1000 wRMS The 3XL series have been designed to withstand the extreme heat that the new generation Class “D” amplifiers create. Class “D” amplifiers heat up the woofers voice coil two to three times hotter and faster than a conventional class A/B amplifier. This calls for Xtreme measures and special parts to classify these as a true “Class D Subwoofer”. But hey, this is PowerBass. PowerBass has it under control. First, PowerBass uses industrial assembly glues that are made in the USA that handle this excessive heat that would normally tear a conventional subwoofer apart. Then there is perimeter venting to allow air movement over the voice coil built into our custom cut, cast aluminum basket. The basket works as a strong foundation for our heavy duty non-pressed raw pulp paper cone and redesigned inverted PBX dust cap.
