HI, New to the forum and have a question.
I have Crites Cornscala Type B and I purchased a complete speaker set. He makes the cabinets out of good Birch plywood but there is no packing or dampening in the cabinet. I have some carpet pad. Is there benefit to wrapping the horn and walls? Is there any chance the screws will strip out if I remove the back of the cabinet? Thank you.

It's worth a try. If you don't feel right taking the back off, you could go through the woofer hole. You'd then want to be careful in torquing the screws when putting it back.
Wrapping the horn and covering the walls with carpet pad will be less effective than simply installing a new polyfill pillow in the middle of the cabinet. Just like spacing acoustic panels out from the walls in your home, any absorber will be more effective away from the boundaries. (walls)
...but be careful not to put much stuffing, as it would mess up the port tuning. I haven't seen the insides-is there any bracing? If not and they were mine, I'd probably put some soft-coupled cross braces, antivibration coating, and some kind of absorbent on like 3 internal faces, to absorb midrange reflection. What @diyuser2010 says "more effective away from the boundaries" I think so too but for reducing internal standing waves...but you have to balance that against the port tuning. Do you have a way to measure the impedance curve? OR more to the point to check the port tuning maybe use sine tones and an SPL app on a phone as a crude measure.
I have a set of Bs as well. I tried different configurations and the one that gave the sound I prefer is an inch of poly on sides, top, back and on top of the port. Without the poly, bass response was weak.
I would measure the Cornscala first to see if there is a resonance that you didn't hear. Then you can fix it for peace (or piece) of mind.
Normally we should not touch a system unless we can identify something "wrong" and after due consideration can attribute a specific mod to solve that specific problem.
