Speakers at the hive

Posted the other day about an issue with a power surge at my home that took out some of my home audio speakers. There are some Kenwood speakers down here at the hive that are loaded with dust and look like they have been here for a while and I was wondering if they belong to anyone. They have a Goodwill price tag on the back in their writing. I was going to test and see if it worked and wondered if it belong to anyone currently or if they are something that has been abandoned? I will add a picture on here of what they are, if they do belong to anyone if you could please let me know and I could talk to you about it that would be awesome. I was going to check the main one out and see if it works and wipe it down as it is loaded with does an any information on who these belong 2 would be great. Thank you.
