I am the original owner of a pair of Infinity 6 Kappa speakers. The speakers were purchased brand new in 1990 and have been simply phenomenal ! The only issue has been surround rot on the bass drivers 10 years. This was lovingly repaired by Jamac here in Portland, OR. Sadly, the last week one of the polydomes on the midrange decided to literally erupt, tear and fall apart (you get to be 30+ years old and see how YOU do). I have one of two options:
1) Order a replacement driver from an outfit called simplyspeakers.com.
2) see if I can locate a re-dome kit
3) ship the offending driver off to be re-domed.
If I go with option #1, I think I would need to buy a pair of midrange speakers (one for both speakers). The difference between the two is the replacement is a traditional paper diaphragm/foam surround. I can get a data/spec sheet for the replacement from SimplySpeakers, but I can't find one (what am I thinking?) for the Infinity model 902-3075.
I could ship the broken midrange off to be re-domed/re-foamed, but I would be without a speaker for 6-8 weeks. (No thank you.)
(Don't suggest new speakers, I can't afford a pair of KEF Blades just yet)
