ReggaeBen Posted August 24, 2018 Report Share Posted August 24, 2018 Ahh...so I'm back to work on my next little project, this time my Aussie 6's. They'd been playing fine and are in great shape already to begin with therefore I wouldn't expect I'll need to spend a great deal of time on this job. Plans for these include - *replace the original tweeters for a pair of later model fero cooled (200014-3). *Boston Acoustics filled fillet surrounds. *Recap with a pair of big russian oil caps that I decided to try. *Fibreglass fill instead of the rockwool. *Bypass the inductor and cap/resistor setup found in this model for the later version that runs the woofer at full range and the tweeter cap to 6uf. *Try out Howards restor a finish (neutral) on the cabs. That's about it I figure but I welcome any more suggestions on this as I'm still fairly new to speaker resto's. Okay... now what's been done, One woofer had a clicking noise when pushed in that was bothering me a bit, I thought It may have suffered from bottoming out at some point and there could be damage to the VC. So curiosity got the better of me and I decided to remove the cone from the basket, very carefully of course! With the aid of acetone and a very potent product called MEK (methyl ethyl ketone) I softend the glue holding the spider to the basket, then used a utility blade to work it up slow and steadily. Bingo, cone now was separated. After inspection of the VC and gap I couldn't see any damage or anything to cause the noise, but what I did find was that the placement of the magnet was not square with the basket or pole "plate?" thus leaving me to think that as the VC lowers down it then gets drawn by the magnetic field to one side and hits someplace in the gap. As I can't see it doing this and Its not at precisely the same point each time, I can only say that what I'm hearing is that grabbing noise when a magnet has pulled something in. Anyhow moving ahead, since I can't see damage and couldn't detect any sonic issue I guess without breaking the speaker down even further then I'll resemble it next. I was lucky enough to find a Sprague compulytic can in the first cab but not so in the second, the first speaker was slightly clearer sounding that the other and this could likely be why. I'll keep up with posting my progress as I go along and hope this help with others that are working on the same speakers or similar models.
