Have you tried some far field IRs? And do you place the CLR on a pole or on the floor?
Try this if you can:
- load a FF IR
- place the CLR on the floor so that the speaker is perpendicular to the floor (just like a guitar cab)
- set the preset switch on the back to FF
This is the closest I could get my CLR to a guitar cab in terms of thump.
But I still prefer my real cab for that, so my current setup is basically a 2x12 plus 2 CLRs used as PA speakers (for guitar, vocals and occasionally keyboard).
My guitar mainly comes out of the 2x12, the (weaker) signal going to the CLRs is just to add some clarity and stereo spread. Best of both worlds.
