Well, maybe this will help the original poster understand the relatively dark sound of Fractal Audio Systems.

Also, it might be helpful to use Cliff's old tip (instead of using cab blocks) by slightly refining it.
For your convenience/try , I'll attach a pre-set block file. Just put it in the correct folder location, place 1 filter block, 1 GEQ block, and load these files from the library, and you're basically ready to go.
oh , and It might also be helpful to mix it with existing dynacab or legacy IR cab blocks.

"Try this:
Make a patch with no cab block.
After the amp put a Filter block. Reset to make sure all parameters are at default values.
Set the type to Lowpass.
Set the Order to 4th.
Set the Freq to ~5000.
Set the High Cut Freq to ~5000.
Adjust the Freq and High Cut Freq to taste. For more aggressive tones increase both to 6000 or so. For warmer tones decrease both to 4000 or so.
Now, to add some "character" put a Graphic EQ or Parametric EQ block after (or before) the Filter block. Boost 125 Hz a little. Play around with some of the midrange and upper midrange bands to change the character of the tone. This is what I used:
31: 0.0
63 Hz: 0.6
125 Hz: 4.57
250 Hz: 0.25
500: 0.0
1K: -5.0
2K: -2.27
4K: 1.95
8K: -1.0
16K: -5.77
The reasoning behind this is that there is no such thing as a "flat" speaker. All speakers, even really expensive monitors have peaks and dips in the response. That's why they all sound different. The primary thing a guitar speaker does is roll off the highs aggressively at somewhere between 4K and 6K Hz. The Filter block replicates the rolloff but lets the natural response of the speaker come through. "
That's an interesting approach, albeit a very cumbersome one and I honestly would just prefer to load an IR instead of EQ'ing one myself. But I appreciate you searching and suggesting Cliff's tip.
It's definitely interesting to see if the midrange boxy sound is still there. If not, then it comes from the cab block or the IRs, though I doubt that pretty much all IR's have the same problem.
