Well I have been installing car audio since 1987 and the Energy speakers that we have are awesome.I myself think they sound better then the Infinity and the Jbl.I can see them being a very good seller.They are in the same price range as the Infinity.They are worth taking a listen to you won't be disappointed.I go into work this afternoon and if I have time I'm going to build a couple of boxes.We have 10" as well as the 12" subs.And if they sound anything near the rest,they will be awsome as well.
