What crackling under what conditions? I've been buried so may have missed it...
A myriad of things can cause speaker crackling, some due to the speakers (like the infamous delamination problem when wires separate from the panels and buzz), some due to component issues (bad coupling caps in an amp or preamp, in some cases high DC offset causes problems), etc. Some people hear buzzing or rasping from a ground loop or EMI/RFI and describe it as crackling so it may be hard to tell without "being there".
If you hear crackling, use pink noise or tones to see if it is frequency-dependent. That will at least isolate the driver. Listen with your ear to the speaker and move around to see if it is localized to one spot or one driver segment. Delamination is buzzing, usually at the ends of the panel, and may go away or get very quiet as volume is decreased. With the new QR design I would expect delamination to be less an issue but I do not know their manufacturing details. Sometimes it may not be the panel itself but something else, like the frame or feet. Years ago I did a call for a customer who complained about his 20's making strange popping noises. He had eschewed our normal dealer setup and did it himself. He overtightened and stripped or spun the mounting screws on one speaker and with large bass signals the speaker was actually vibrating, buzzing, and occasionally "whacking" against the footer.
If it is in one speaker, swap speaker cables (usually easier to do at the amp end) and see if the problem stays with the speaker or follows the amp. If it is in both speakers, that would be unusual unless they are both defective/broken.
If you have another amp/AVR try that to see if the problem is still there. Be aware a bad preamp may cause problems with any amp. If you have another pair of speakers, any speakers, hook them up and see if you have the same problem (implying amp/preamp/AVR/electronics not speakers).
Hope this provides some things to try. If they are new, contact your dealer. Hopefully he'll bring or loan you a replacement amp/AVR to try.
