If someone has the Daytons you mentioned and are willing to send them to me for testing, I'd be happy to test them. I contacted Dayton directly this afternoon with a link to my video and explained many were asking if I would include their speakers. This was the reply:
That is interesting. I can't imagine that other reviewers both big and small were all paying for their Daytons.
Someone from Monoprice got back with me and will be sending out the $99 12-inch along with their 10/12/15-inch monolith subwoofers. Not sure when. I will be sending them back once they have been tested.
Good to hear. I have had good interactions with Monoprice in the past. Unfortunately, I couldn't help you as I haven't spoken with anyone there in over two years.
You didn't say or maybe they didn't. I will be interested to see if that is the sealed or ported Monoliths.
