Hey All, I know this is an old thread, but I have some questions. I ordered a set of foam surrounds for my FiL's BOSE 601, series II. He bought them new back in the '80's, while in Singapore. He also has a set of 901’s (I think), but prefers the 601's. I have seen YouTube vids showing how to replace speaker surrounds, but have never done so myself. So for my FiL's B.day, the vife and I thought it would be great to get his 601's back up to spec. I have ordered the surrounds(x4), it comes with some glue, but I am sure that it is only a token amount, and not substantial. What tools, will I need to remove the old surrounds (putty knife, razor blade, etc...?) What is the best way to remove all of the old surrounds still attached to the driver? (A solvent or just the above?) Is it necessary to remove the dome's dust cap, and if so, what is the best way to re-attach? Also, as mentioned, the surrounds come with glue, but is there a more specialized type of glue that I should use? Epoxy, Rubber, Super, etc…? Lastly, since this is a Birthday gift to my Father in Law, what other things should I do to the speakers to make them whole again? I see that these have four tweeters per speaker, is there something that I can do to those, that would help them along? Any help is appreciated, Thanx.
