I own a Single 12in L7, and i just picked up a 12in W7, I'm thinking about selling the W7 and L7 and getting 3 Type R 12's for like $300, and putting them in a 7.5 cubic ft box tuned to like 33hz and giving them 1800 watts rms, and spend the remainin money to upgrade my electrical system //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif.
