I am swamped and not taking anything new until I can catch up. Just joined since my Sub 12 is now blowing fuses. I did check the resistance of the speaker and it is 4.5 ohms so it appears to still be good to go. Just curious if you knew if a replacement amp for the Sub 12 model is available. If not, do you know if a replacement amp for a Synergy Sub 12 would work (Part number 1012532...replaces part 119511 - US version)? Reason for asking is because I have found one of those. I really like the sound of the sub in the room it is in so don't want to start looking for a replacement. Also like how it is a down firing 12 with the port in the rear. The larger down firing subs are harder to find. Thanks in advance. Quote Link to comment Share on other sites More sharing options...

I bought 2 used Klipsch sub 10 subwoofers ( with quintet III) from Goodwill auction. I liked the first speaker set with the Quintet III so well that I got another set with the sub 10. Both worked fine, until the second started blowing fuses. Now my first one has no sound, but the power stays on. They are probably not worth fixing. I contacted Klipsch, but they won’t give me a schematic on them. I probably can’t fix them anyway? From what your writing, it sounds like there is no way I can cheaply fix them? Cleveland. I have a massive waiting list but I do have some trade-ins listed on eBay. Quote Link to comment Share on other sites More sharing options...
LarryM Posted July 18, 2021 Share Posted July 18, 2021 I have a sub12 subwoofer. The auto on/off stopped working. It is always on. Do you know what I need to replace to fix this. The amp number is 119511. Thanks Quote Link to comment Share on other sites More sharing options...
RadioCaledon Posted July 24, 2021 Share Posted July 24, 2021 Very interesting. I'm working on a Polk PSK125 and discovered the PDC board used is exactly the same. Perhaps it's a rebrand or OEM Part as it is labelled INDIGO. I'll have to do some research and see. I think the PDC is also the source of my troubles, which is a crackling noise followed by blowing fuses. Significant burn damage to the rear of the PDC board. In the Polk amplifier the PDC board sits next to a couple of resistors that seem to get very hot. I'll be replacing the resistors with something that can handle the heat a bit better, but trying to decide the approach to repairing the damaged the back side of the PDC board. Trying to decide if I can simply jumper the appropriate traces to prove that's all the damage and then perhaps its best to design and fabricate another board and replace it altogether. The traces on Pins 1 & 2 of J6 have been obliterated and the outer layer of the board damaged up to the level of the lower diodes Quote Link to comment Share on other sites More sharing options...

I think Klipsch only made it for one year One 10” and two 10” pas drivers and a 500 rms amp. Mine is dead , green light comes on but no sound The resistor were 1k ohm instead of the 750 ohm. everything else was the same my card was a indigo PDC like in the picture. Mine was working but I pulled out too replace it and that was the only thing different on my card 1k ohm instead of 750 ohm Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

I've been having fun mapping out a replacement board using ExpressPCB and will first try to etch a replacement. Currently stalled because I'm having trouble sourcing the NTE6412 DIAC up here in Canada. Seems there is lots of NOS availability in the US, but shipping as high as $28 to get one up here. So biding my time until I can find one or travel across the border again post covid 🙂 Digikey had an equivalent HT60RP, but it also is obsolete and they recommend a DB4 as a replacement. However the breakover voltage is lower (35-45) and I don't know enough about the design to know if they are suitable substitutes.. Quote Link to comment Share on other sites More sharing options...

Especially if I wish to get more than qty 1. I have time to either find one locally, or wait until I can cross the border and get one at a better shipping cost.

JonHolets Posted August 29, 2021 Share Posted August 29, 2021 I have a sub-10 that is basically never been used. Bought it for my dad 15 years ago, he never really used it, so he recently gave it to me. It distorts with a metallic sound at even low-medium volume. As a complete novice, I figured there was a voice coil issue. I replaced the speaker with a new crewin Vega. Sounds exactly the same. Keeping in mind that I don’t understand most of what is on this site, is there anything I can try? Hate to waste this. thanks in advance.

T_S Posted September 1, 2021 Share Posted September 1, 2021 @ngen33ri had one amp gone bad.... looks like my second sub is going down the same route. Happy i found this... Is there a way for me to send mine for repair? it makes a loud clicking sound. Quote Link to comment Share on other sites More sharing options...
Conrad787 Posted September 2, 2021 Share Posted September 2, 2021 I too have a Klipsch Sub-10 in need of repair. Any takers? I'm happy to ship you the broken BASH amp. Pretty sure I have the identical issues described above in this thread. Quote Link to comment Share on other sites More sharing options...
ngen33r Posted September 16, 2021 Author Share Posted September 16, 2021 I am swamped with repairs for now. I have a huge waiting list and summer is busy as hell for me. I do offer amp swaps on 3bay when I have the time to get a few snuck in. Life ruins my hobby. Quote Link to comment Share on other sites More sharing options...
Latinskllz Posted October 27, 2021 Share Posted October 27, 2021 (edited) I have a SUB-10 with no sound. The LFE signal appears to be working as the Auto-On is going from sleep mode to on when receiver seems to be sending a signal. It was working for some time after the replaced the capacitor and added thermal paste circled in green. I am trying to troubleshoot myself for a learning opportunity. testing resistance on sub yields 5.3ohms, is this acceptable? I believe it’s an 8ohm sub and thought that I should be around 6.4ohms or 20% of 8ohms. just trying to see if I can do use basic tools to trace root cause. I really like the sub and would love to avoid ditching it. Edited October 27, 2021 by Latinskllz Quote Link to comment Share on other sites More sharing options...

Welcome, sorry but i can't help with finding your problem. But if you wanted to keep it you could use a outbard or stand alone amp, no reason to ditch the sub. A regular amp could be hooked up and just put the bad amp back in it's place so the cabinet space stays the same. . 1 Quote Link to comment Share on other sites More sharing options...

The PDC control board failed and took out the mosfets. I had to clean and rebuild the PDC, replace the fets, replace Q5 and TH3. TH3 is almost always bad when fuses are blowing. After the board was working, a full recap was done on the amp.The active crossover was especially fun due to all the damn glue used. Are you able to help me fix mine, something is happening to mine Quote Link to comment Share on other sites More sharing options...
