Batman. Thanks for the input. I did do the HX crossover upgrade myself. Roy sent me the new crossover with very detailed instructions to install with a new Marigo wring harness. Seemed to make a significant improvement, so what speakers. I did the plumbers putty thing on the woofer as well. So what speakers did you move to?
Past or current Green Mountain C-3 owners
I own a pair of Green Mountain C-3 with the HX upgrade. I am currently driving them with a Coda N0.8 amp and a Lumin A1 directly using the Leedh volume control. I also have a pair of Seaton Submersive subs that I bring in under the C-3s that are running full range. I am quite happy with this system, but given the passing of Roy Johnson and the replacement tweeter becoming unobtanium I want to be thinking about where I might have to go next in the future. The C-3s just totally disappear in the room and I attribute a lot of that to Roy's design objectives of maximizing phase and time coherence as well as minimal diffraction enclosures for the tweeter and mids. I have other speakers I can rotate into this system in a pair of Martin Logan Summits and a pair of modded Klipsch Chorus IIs (fun speaker). Neither of these could replace the C-3s.
My question to past or current C-3 owners is what speaker have you moved to that gave you equal or better performance to what you got with the C-3s? Thanks for your insights
