1 ribbon came out flawless, (the second one...) while the other has a couple of wrinkles around the bottom where the PCB is. No problems sonically/no buzzing so far, but I'll give them a few weeks before I determine if I will have to rebuild the wrinkled one.
I was prompted to get off my ass and do them after I purchased the ALIII+ speakers without the ribbons for $200.00 on Ebay. They were just 45 minutes from the house, so I went and picked them up (smelled like cat piss, had to clean them really well before the wife would let them inside...) Have them hooked up to a Sunfire 300 X 2, but was wondering if I would do better biamping them with my Cinema Grand 200 X 5. Figured there would be about 400 watts (4 ohm) to each woofer and ribbon, so it might sound better than just the 300 watts to each speaker in the current setup. Interested in anyone's opinion on that one...
SOOO, I have a couple of 60" ribbons (needing repair, of course) and a pair of Plat regular and Mk IV crossovers, as well as 8 new Plat woofers from Dynavox to upgrade my original ALS'. That will be my project for the next couple of weeks.
DaveS has been great with his patience in answering all of my questions and walking me through the first ribbon. I appreciate all of his time and knowledge that he generously shared with me.
