I have a nice pair of MG944s that I'd like to sell.  I already have a few interested buyers; however, I've not officially put them on the market as I'm not sure how to ship them.

Any advice?

I sold a pair of Martin Logan Theos just  before I jumped all ib for Decware and Omega. UPS. They were about 40 lbs. each.  Original shipping boxes. PA to GA. Cost $500 and the buyer shared none of it.

The seller put my speaker cabs in shrink wrap surrounded by 3/4” foam board panels when they shipped to Alabama from Boise and they were perfect. Shipping was $60+ for empty cabs. The 946s were pretty much the same packaging, foam insulation board all around and UHaul boxes cut and taped to fit. Because the speaker posts extend so far the aluminum panels took some dent damage, not because the shipper was neglectful but because the delivery included rolling the box out of the truck down the drivers steps to the ground. The Monolith horns, packaged the same way took no damage. Shipping was over $150 from FL to AL.
