I would not like a wiggly binding post. How much to make about the packaging and transport to me also has to do with the quality of the product we are talking about. I am not trying to diminish importance of the issue. But Acoustic Energy stand mounted speakers vary in price new from around $500 to around $1600. So used, they are unlikely to be more than $250 - $800. My reluctance to shrug off a little problem, or fix it by pulling a woofer is strongly related to the cost of a speaker. If the speaker was $10K, or $20K or more new... I would be really reluctant. Wanting a professional solution. But in this price range, I’d pull to woofer and tighten it.
If it was a much more pricy speaker, I would buy from a dealer. I would say given the cost of the units. giving it to UPS was a reasonable choice. I am sure the vast majority of the time they arrive in perfect shape.
