FCC requires a tag showing make, mod #, watts, amps, UL etc, etc. I used to do flooring checks for various companies handling speakers. Look for it on back or maybe bottom. Where does it say Sonora. If you opened any of the links I sent, you will find company names, etc. It's easier for you to look than me.
Tom, I did open all the links...where do you think the above link I posted came from? And with all those links, there's still nada about the company. Which is why I asked the question. The Sonora company profile doesn't even seem to be the same company as what I'm looking for. I was hoping someone might KNOW something. As in - if someone asks me if Fenton made vases..well, I know the answer to that. That's why I was hoping some stereo aficionado would be able to see this post. I can Google, but Google certainly doesn't know everything.
I'm trying to find out if they're still in business, if not, then when they were, where they might be located and if there's a way to reach them, or possibly whatever company bought them out. That information seems to be vague. So settle down, and quit being so snappy.
