B2 Audio XC 18" Subwoofer

In order to make the XC series as massive as they are, we had to overdimension everything, but still make every part have a function as intended. Therefore all XC subwoofers share the exact same 462 oz magnets & 4" voice coil configurations.

These subwoofers already hold the 2011 World Record in dB Dragracing**, but fear not, they will ensure SQL as well as SPL. Look at the paramters & you will see that music is no problem for any of the XC subwoofers.
