Need help identifying these speakers purchased in 1992

I'm not sure you'll find much of a market for 30 year old brand-less, bookshelf speakers.  I suppose it could be helpful to find out who the manufacturer was to list on a Goodwill donation receipt.  I think the tax deduction may be the best bet.  Otherwise I'd gift them to a friend or relative which is good karma.

Those are Essence Gems. Nice set of speakers that should fetch $400-$500 to a buyer that knows about Dale Pitcher and his products. 

I should qualify that price as based on condition. A 8 of 10 Audiogon scale set would be in the range mentioned in my above post. Make sure you understand what 8 of 10 means when rating. Here is a link to what was their flag ship at the time the Gems were produced.  https://www.audiogon.com/listings/lis9gfi3-essence-amethyst-10a-full-range .Not many people know about Essence Electro acoustics products. You almost never see one of their amps for sale, and in 20 years I have never seen one of their preamps for sale. People that buy those products get off of the buying merry-go-round, permanently. 

Thank you so much!  As soon as I read the name my memory was jogged. I was blown away the first time I heard them and they’re still pretty remarkable.
