Replace Dynaudio woofers?
Hello. I have a pair of woofer blown Dynaudio Contour 1.1s They have been sitting, unused, in a clean, temp controlled room for at least 15 years. I hooked them up recently and the tweeters were emitting sound.
Is it worth to source OEM woofers to replace? Is it an easy job I can manage myself? Any advice would be appreciated. Thank you in advance.
Ok got one out. Ours are different because mine did not have that thin black strip. Glued all the way. I lifted a bit while my partner made tiny slices in the glue. After three or four, it all started breaking down. (Sorry still don't know how to post images) Now the part I had dreaded all along: I don't have any soldering skills. Do I need them to test the driver/crossover? I was under the impression that ferrofluid can dry over time and cause damage/distortion in the tweeter. |
Dynaudio drivers cannot be repaired, email Dynaudio and they will put you in touch with the nearest authorized dealer so you can order a new one. You only need to replace the one that damaged and why your add it replace that terrible internal wiring. Replacing the driver and wiring is easy if you have even a little bit of diy experience . |
@xidnpnlss Your first challenge will be de-soldering! If you’re not up to investing $200 or so for some decent soldering kit, you might consider taking the crossover to a local tech shop or friend who can undo and redo the joints for you. Of course, you could get by with a 25 Watt iron and a ‘Solderput’ sucker (nothing less, no substitutes). The component that blew up on the one board was one of those ‘$2.00 resistors’ referred to above, often termed ‘sand resistors’ —they are not expensive. The other commonly replaced items include any electrolytic (‘can’) capacitors, as they dry/wear out after years of service, even if they’re not used. Again, not a terribly expensive part unless you’re going for super high quality. Parts Express can hook you up. Would be a shame to have them fail soon after you get the speakers all reassembled. Original performance will also be restored. Good job on getting the first woofer out. I approve of your method, for what it’s worth. Good luck with your project, I’m sure you’ll be pleased with the result. |
@tecknik Yes, I know that blown drivers can't be repaired. I already have the part number from Dynaudio and some good aftermarket recommendations from the thread. My situation now is figuring out if it's actually the driver that's blown or the crossover. What would you recommend to replace the wiring? @oldrooney Thank you for the support and commendation! And thanks for the bit of knowledge on the components. If I already knew how to solder I'd be all over this.. But I dont and I'm actually not at a place right now to learn or invest in a good soldering set-up. Someday, for sure. I'll be calling around techs after the holiday break. I'll be sure to update this thread with whatever transpires! Fingers crossed thrice it works out. |
It looks like Dynaudio is using standard 12ga copper wire. There’s nothing wrong with that choice, it does the job, especially considering you are talking about runs less then a foot. I’d cut the ends, strip back some fresh wire and reuse it after you have gotten the crossovers repaired. See if there are any speaker repair shops near you, they can fix the crossovers. Or give GR Research a call (1-940-592-3400) they could probably make replacement crossovers as well. The cost to repair can vary greatly depending upon the level of parts used so stick to a budget and don’t let them talk you into high end stuff. I’d keep the budget under $200 for the pair that way you have some budget leftover to replace the drivers. Assuming the cabinets are in good shape I’d peg their value at around $600-700 w/ fresh crossovers, and $900-1000 with fresh crossovers and new oem drivers. |
