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.
UPS Stores (not the same as UPS the carrier) use bubble wrap and/or styro peanuts. I’ve never seen them use foam. That’s not OK for our purposes. A proper foam cradle / cage is THE way to pack expensive & heavy gear. Two types: open cell, closed cell (polyethylene). Both fantastic. Closed cell is better for the heaviest items. This is what companies like ARC and VAC use, for good reason. VAC’s foam material in particular is fantastic (multiple layers bonded). You can get similar foam on amazon; it’s not cheap. I’ve used that before, cut to purpose, for the rare times I didn’t have factory packing of a heavy component.
