I decide to start this website because almost all vintage Loudspeakers have troubles with old foams /surrounds. Most speakers from the 80's and 90' where sold with foam surrounds , after 15 years are the foam’s damaged –but nothing to worry about – it is possible to replace the old surrounds with new one’s. After that You can enjoy another 15 years of music. After repair the speakers has the same Frequency response, look like new and sounds like on the first day of use. Hope You find on my homepage interesting info about the foam surrounds, you can also see photos of speakers I have repaired and a Infinity Vintage Gallery. If you are looking for parts ore vintage speakers feel free to ask - I can try to contact you with other infinity freaks
