3000iphones Posted July 3, 2020 Report Share Posted July 3, 2020 i have a d2 sundown sa-12 v2 that, when pulled out of it's previous enclosure, was working well with no signs of anything being broken or damaged. it's been sitting for a few months now, and i got a second one with a new enclosure. disconnected, it reads ~26 ohm. i wired them together, and the reading at the amp was something like 26-30 ohm wired series/parallel. i can push the dust cap/cone down and it'll feel just like the new sa with no scratching but scratches with bass playing. i knew there was a problem at that point, and i'm wondering if anyone has any insight here. is it easily fixable by an amateur? is it worse than i think?

That subwoofer needs to be reconed or replaced if you do not know how to recone it with a recone kit or know somebody that does. thank you. that's what i was looking for. so i'll learn how to recone a sub soon i suppose.

Turn the amps gain down that was on that sub too because you most likely was clipping it and making the voice coil way too hot. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
1point21gigawatts Posted July 3, 2020 Report Share Posted July 3, 2020 To tune an amp’s gain correctly you need to purchase a smd dd1 or make a distortion detector. Because clipping/distortion is the main culprit of blowing subwoofers. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
1point21gigawatts Posted July 3, 2020 Report Share Posted July 3, 2020 Self made distortion detector. capacitor that’s needed. https://www.parts-express.com/33uf-100v-electrolytic-non-polarized-crossover-capacitor--027-328 “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
1point21gigawatts Posted July 3, 2020 Report Share Posted July 3, 2020 The smd dd1 (it’s better because it can tune mids and highs amps too. The self made one can only tune subwoofer amps.) https://www.wccaraudio.com/smd-distortion-detector-dd-36.html “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...

Because clipping/distortion is the main culprit of blowing subwoofers. i'm sure i was clipping it, probably due to my voltage being at 11 and the wolfram wanting 14 instead of my gains being ignorant. i smelled glue, but i heard different opinions on that glue smell. either way i won't have those problems anymore. thank you for your time. **edit** also, it's strange it'd go out while sitting instead of being in use.
