I dont believe anyone mentioned anything about an 18 let alone any size. I believe the comparison was between the SX, R, and Solo... I am sure no one was trying to compare a 10 inch solo with a Type R 12 against an SX18 //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gifi meant as far as cone area with the L7's.
the 10=12, 12=15, and so on, becuase they're sqaure instead of round.
and the SX comes in an 18, where the R doesn't.
and definately price differnces between them.
