Is there anyone out there who knows anything about Essence Speakers by Dale Pitcher?


I have read all the threads I can find on the web about Essence Speakers and about Dale Pitcher. I met Dale at the Essence plant in Lincoln in the early 1990s. I know about his eccentricities but found him to be a genuinely nice guy with a great passion for audio. I have owned a pair of early Gem speakers and currently own a pair of Gems from near the end of their production run. His speakers are amazing. I would like to become acquainted with other Essence owners and fans of the Essence product line. I have recently found and purchased a set of Essence Topaz 6 speakers from the mid 1980s paired with a pair of Topaz Subwoofers. Is there anyone out there with any literature, pics, documentation, history,  setup procedures, or an interest in having an informal club or chat room to share the joys and sorrows of these wonderful speakers?

I have the manual and wave launch charts for the Topaz 6. Several years ago, I sent the midrange, tweeter assemblies with cradles, and crossovers to Dale for upgrade. They never got finished and I don’t believe they ever will. All I have left is the bass enclosure with upper sides, the tops, and the bottom plinths. I could send you copies of the manual and charts if you are interested.
Don't know a lot about them, but when I heard a pair, I liked them very much!
Like I thought my brother does not have the manuals. Looks like someone else does, thats good.
No one ever mentions the Essence 8a. It had the same driver complement as the IMF TLS80 and RSPM MK IV. The 8a had an aperiodic bass chamber instead of a TL. I thought the 8a was an homage to John Wright and his designs. It was a beautiful loudspeaker.
I just stumbled on a set of Essence speakers and I’ve been trying to identify them. I posted a discussion about them already but I’ve included a picture of them. I know very little about speakers but they looked and felt very high end so I bought them. Any help is appreciated. Thanks a lot.
