I dont think anyone is hating on JL, they're stuff is awesome, the only thing I think anyone is saying is that with JL, some of that price if definately paying for the name. at the $200 per sub range, DD has thier 1500 series, which are killer. In the right box, they are punchy, solid, and got drop like a son of a bitch when you need them to. But, in answer to your question, the JL's are a definate upgrade from the CVR's
