Thanks Chris. I actually found the PDF copy in one of Roy's emails he had sent me from a few years back when I bought the speakers.
I was waiting for the RX ribbon upgrade but unfortunately as you know Roy passed away.
I've just ordered the new Spatial Audio X5 speakers which I should be receiving in a few weeks. Have listened to another open baffle speaker at a friends that I really liked so looking to try something different. I've had four different Green Mountain audio speakers for the last fifteen years and love their sound but want to try the open baffle approach and see if I like it or not. I will have 60 days home audition in case I prefer the Green Mountain Audios, we will see.
How long have you been using Green Mountain Audio Speakers?
Thanks,
Marcello
