Glad to find these at such a good price for my 1980's Acoustic speaker columns, 2x12+horn. I use with my band regularly and blow the diaphrams from time to time and need affordable replacements.

Speaker Diaphragm
with only moderate skills I was able to replace the diaphragms following there tutorials online (make sure to clean the magnets well!). The horns are now as good as new thus saving substantially on replacement speakers.
