R.I.P: Rest In Peace Roy Johnson, Green Mountain Audio's Genius

All,

It is with heavy heart that I bring to you the heart breaking news of the passing of one of audio's true geniuses. Roy Johnson passed away this week after a long battle with cancer. He was a truly brilliant speaker designer, and true friend, and an amazing person. For those of us lucky to have known him as customers or friends we know he was infinitely committed to lending a hand, imparting his wisdom, solving problems and creating some of the most amazing loud speakers ever heard.  There were often gremlins in my system not centered around his loudspeakers and Roy would literally drop everything and help me trace down problems, while all the time educating and teaching me, not for gain, not for money, but because that's who Roy Johnson was. 

He will be greatly missed for his humor, his dedication, and his selflessness in audio and in life.

Rest in Peace Dear Friend,

You Are Loved

I am reopening this discussion for a specific purpose. I too have long been a fan of Roy's speakers and owned a number of his models. I still have EOS and had ordered (and paid for) the RX (Ribbon Tweeter) upgrade.  I am sad at Roy's passing and I get he was probably doing the best he could do to get through his last years (as all of us will do). 

Having had many emails and discussions around the design, I would like to complete the upgrade, purchase Raal (or equivalent) tweeters and build my own version of the enclosure. I have all the design photos and details. The thing that I am missing is the xover circuit, although I have a photo of the final circuit, I don't have the values for all of the circuit.

So Wondering if anyone out there has more information and is interested in completing this great project for Roy.

I have some pictures that Roy sent me of the crossover circuit. Unfortunately, you cannot see all of the values of the caps and the resistor in the circuit. The other thing, form my discussions with him, was that the RAAL ribbon was being ordered specifically for these speakers. He was going to have the transformer wound to provide a specific impedance he wanted for the crossover design. I have no idea what that value is. I was told by him that he had tweeters on hand, but have no idea if that was true or not. Maybe RAAL can give you an idea of what was ordered for them. If they were never ordered or they won't tell you what the value was, I would think that it would be very difficult to incorporate into the speaker. Good luck

I know it may be late but I have just tried to call him as we were working on a speaker project together, but alas no number was working so I looked up his name and alas I found out he’d passed on. 
I’m not even sure how or what to say except that to me he was easily one of most honest sincere people I’ve met in our industry and really anywhere. 
He and I would talk allot about many things not just his speakers lol. 
All were captivating and full of flair. It’s really difficult when people you care about go, it really is. 
Rest In Peace my friend
