I do have an 2 JL hd 750 running each sub. The hd was recommended, and glad I did. I live in the midwest, and to be honest, there are a number of subs I've heard of that aren't sold here by anyone. Kansas to be exact. I'm pretty sure our audio shops aren't what the west coast, or east coast are. In other words, I'm sure we lack diversity, and knowledge. Good bad or otherwise, the most highly touted subs are JL, Kicker, Fosgate, MTX, Alpine........... you get the idea. I have found one shop that sells Morels........ Heard they were good, but......... Anyway, we are a simple folk, and most go with the "name" before taking a shot on less heard of. One has to go out of state to even hit a show. It's sad really............
