I'm having a difficult time trying to track down information about the speakers that come with the Spider IV combo amp and the Spider IV 320W 4x12. Everywhere I look, the only info they give is the line, "Two custom 12" Celestion speakers", so I assume 80w. But why isn't there any info about them at all anywhere. The Spider Valve 412 cabinet boasts that it comes with Celestion Vintage 30's pretty loud and clear and are priced twice as high. Yet, these remain a mystery. It just concerns me that there isn't any more info about these speakers out there. I'm trying to figure out if I might want to replace the speakers with better one's, but I can't compare them to anything because I have no idea what the specs are. It's almost as if they don't want you to know.
