I have a 3/4 QB widebody ext 1x12 with the C90...it is a great cab. I paid $249 a few years ago at local GC. I don't know if it was the porting/open back but it sounds really bigger that it is. I use it with a DC-5 widebody combo that also has a C90 so I run it essentially as a vertical 2x12 setting and it sound great and like I'm pushing a 4x12 but I'm not.
