The nine drivers in each speaker may have foam surrounds that tend to rot away with age. Take a look! Regarding the Bose equalizer to boost bass frequencies - throw it away! All it does is add distortion by over-driving those 4 - inch cones! Use a pair of subs crossed over at 60hz.
Bose 901 low serial number set (3 digit) with "patent pending" sticker
I have inherited a pair of Bose 901's that were just removed from the first time since they were installed (early 70's?)
We have tested them out and they work, but I am having a hard time trying to get a year and possible value.
The serial numbers are LOW. (#499, #452) and the sticker is typed and says "Bose Model 901 Loudspeaker Pat. #3,038,964 Pat. Pending"
Anyone have any idea where I can get info?
