There's not any other company out there offering a 50 pound monster for 250$. This sub is more than I could ask for. Dual spider nice true 8 guage terminals. Great quality product will be buying more. Don't look anywhere else skar audio is the best bang for your buck period. I compared it to the 500 plus dollar sundown x and the magnet is exactly the same size. You can't go wrong with this vxf 15.
