Good luck with your search. I have owned several of Roy’s speakers, one being the Imago IV. Definitely worth repairing.
I do know he was fond of Morel drivers.
replace Mid-range speaker of Green Mountain Audio Imago VI
I need to replace the mid-range speaker of one of my Green Mountain Audio IMAGO VI speakers. It buzzes. In 2008, Roy Johnson upgraded my IMAGOs to a unique Series VI. Except for this annoyance, they sound as wonderful as ever. Does anyone know the particular mid-range speaker Roy likely used and from whom I can buy it?
