Could anyone guide me to some frequency response graphs for a 12" XXX snailshell? I know you will tell me to search, but trust me I have tried and came up blank. I have a 15" and now a 12" XXX as well and I like the 15 sealed but I'm definitely looking to sell one of them. I would really like to try out a snailshell box after all I have heard about them. My trunk isn't tall enough to fit a snailshell for the 15 so I am thinking about keeping the 12" instead. I'm just trying to do a little research to decide if I should keep the sealed 15 or put the 12 in a snailshell.
