And most recently for the last five years Skar EVL 12s x4 I ordered these to replace the EVL and when they were delivered, I was shocked at just how much better quality every single part of the subwoofer is just from the feeling and quality of the tone surround to the basket and venting to the sewn in 10 leads push terminals and overall sign these below Skar out of the water I am extremely happy with my purchase and will submit a secondary review once I have all four of them installed in my car
