Many 2 way boxes (FRFR) have inherent problems by design. Not saying they are bad, just physical laws that can't change.
Many issues occur in and around crossover bandpass frequency (typical 1.6k for most)
Coaxials do a better job than horn/driver mounted systems on flat baffles. IMHO. An IR taken from a standard guitar speaker cabinet, processed through any driver/horn wedge will have inherent problems. Electrical and physical.
I went back to a traditional cabinet for these reasons, sometimes using an IR as a "tuned filter" for certain desired resonances.
The 3 dB peak at bandpass is going to be there on powered wedges. Subtractive, or additive, depending on filter order. Bad place for guitars to be getting weird in. Maybe Atomic designed active filters and cabinet porting, tailored to guitar response curves. I imagine the CLR's are not as good for a vocal wedge either. Try the inverse. If your using a wedge that is designed around vocal responses, use your ears to tune it to emulate a guitar cab. I measured my old FRFR, and filtered accordingly, and had pretty good results.
I get your general drift, and agree that some monitors have problems or are tuned for a certain range/instument/voice or whatever - But the CLR is designed to be a true FRFR monitor and while not 100% perfectly flat (show me a stage monitor that is !) it is a really darn flat FRFR monitor, meaning that is does indeed work brilliantly with vocals, keys, bass, program material and so on.
It's NOT a guitar specific product, and as such is not tuned around guitar frequencies, but rather around being a flat FRFR system.
