I just bought myself a pair of NIB Celestion Impact 40 Speakers at auction of an older Audio Store that went out of business a couple years ago. They seem to be awesome speakers but there wasn’t any technical paper work with them. Can any of you furnish any info on these speakers? When were they manufactured? Were they considered good speakers in their day? What is the best way to use them to obtain max enjoyment? Any help or suggestions will be appreciated.
