I purchased a pair of Focal speakers from a seller on the other site. The speakers arrived fine but reeked of some funky floral/soap smell. I wiped down the speakers with multiple passes of distilled water followed by a quick drying. I eventually got rid of the smell. I still have the speakers after two years and continue to enjoy them.
I also purchased a pair of Aerial Acoustics on eBay from a seller in Colorado several years ago. They stunk of a strong mildew odor. Not receiving any satisfaction from eBay or the seller, I took the speakers completely apart and wiped everything down inside and out with denatured alcohol. I then left the cabinets completely disassembled for about ten days to air out in my garage. I eventually put them back together and enjoyed the speakers for about five years. I still have them. I might use them in my bedroom with a DAC and streamer.
