Ken98 Posted January 12, 2020 Share Posted January 12, 2020 Hi there I have a Pair of DIY speakers that i have been enjoying now for about 2 years. In the last few days or so I have noticed a buzzing/rattling sound coming from the one of the Scanspeak Drivers. It also makes a weird noise when I gently press on it. This driver is the Scanspeak Illuminator 18WU/4747T00 4 Ohm Aluminium Cone version. Don't exactly want to pay the $500 or whatever for a brand new driver, Is there any one in the country that could repair this back to original specifications or am i just going to have to shell out the bucks for a new one.

Dalspec Posted January 12, 2020 Share Posted January 12, 2020 I had a subwoofer that displayed a similar issue. In operation I could make the noise go away by gently touching one part of the rolled rubber surround. To me this suggested the coil and magnet were fouling. Out of curiosity I pulled out the driver and rotated it 180 degrees. No change. I then pulled it out again and rotated it back 90 degrees. Bingo, noise gone and has been working fine for the last 2 years. It might be worth a shot in your case. There's a bit of info here that might also help: https://www.electronics-notes.com/articles/audio-video/loudspeaker/repair-replace-speaker-coil.php Link to comment Share on other sites More sharing options...
VanArn Posted January 12, 2020 Share Posted January 12, 2020 (edited) From the description of the problem it is most likely that you have a damaged voice coil. Care is required to repair these expensive speakers as it is relatively easy to create wrinkles in the aluminium cone when dismantling the cone from the frame . This procedure is necessary to straighten or de-kink the coil winding or former. I would suggest that you contact Garry Cawsey garry@cawsey.com.au . also in Melbourne. You can ask for a test report ( T & S Parameters ) to make sure it meets the Scanspeak specifications after it is repaired.

Ken98 Posted January 12, 2020 Author Share Posted January 12, 2020 Thanks for that suggestion. I need a drill to remove the front baffle and drivers so will have to wait for my dad tomorrow, but while playing a low frequency tone (70hz) I pressed down on part of the rubber surround and it went away. I playedthe tone for a few minutes afterwards and it appears ok. When pushing on the left side of the surround the rattle/buzzing noise comes back though but as long as i push down the right side it seems fine. Here is a google drive link from sound recording i took of the driver. https://drive.google.com/open?id=1A2Lcu5hxxWF5F6NJMYPHLT670-ENsiCF The first recording is me playing a 70hz tone with the left speaker making the rattling/buzzing noise The second is of me gently pushing against the driver and it making a weird noise, completely different to the other scan speak driver in the other speaker.

Al.M Posted January 12, 2020 Share Posted January 12, 2020 You can also try rotating from up to down the driver so that gravity pulls the cone down and it might be enough to stop the voice coil rubbing. If doesn’t work then see a repairer. 1 Link to comment Share on other sites More sharing options...
