Muddster Posted September 9, 2021 Share Posted September 9, 2021 Looking to buy old stock, new replacement amp for my RT-12D. Also if anyone has had any luck repairing these and what the cost is. Thank you for any help. Quote Link to comment Share on other sites More sharing options...
Rockets Posted September 10, 2021 Share Posted September 10, 2021 Been there, done that. I had mine repaired and it promptly failed again a week later.😡 My solution... Get a Rolls MB15b Promatch 2-Way Stereo Converter, and a Crown XLS1502 Two-channel amplifier. You need the converter to bump up the "line in" signal to a "Pro" level to feed the Crown. (trust me on this). Set the Crown up in 'Bridge' mode, configure the DSP setting on the front panel, and you're pretty much done. Is the DSP as nice as what was built into the Klipsch Amp? Not even close, but the subwoofer itself works great! I also have more confidence in the Crown amp than the Klipsch (which have a dismal track record). BTW, the woofer inside the RT-12d has an 8 ohm impedance, so you can't just connect any 'plate' amp to it. Good luck! Quote Link to comment Share on other sites More sharing options...
BATMAN5892 Posted September 11, 2021 Share Posted September 11, 2021 I had mine repaired a few years ago. Faulty, cheap, Chinese mosfets was what I was told was the culprit. Cost was around $250 to repair it and it has worked for 3 years. 1 Quote Link to comment Share on other sites More sharing options...
Rockets Posted September 12, 2021 Share Posted September 12, 2021 I wish my 'repaired' amp had lasted 3 years. I couldn't justify throwing another $250 plus shipping (over $500 total between two repairs) only to have it blowing fuses again in another week. Don't get me wrong, using the OEM amp would be preferred, but for me, having been burned once, the risk vs. reward wasn't there. The Crowns usually go on sale around Christmas. 'B' stock units are $380 on fleaBay. The Rolls unit is $56. So, pay roughly $440 one time, or roll the dice, and get yours repaired for $250 plus shipping. The risk would be to end up like me and having to pay the $250, plus another $440 ($690 total) after the repaired amp fails and go the Crown route. Understand that I could be in the minority of having the OEM amp fail twice. Another issue is, after paying for the repair, even once, for that same cost you could get a new subwoofer. WOOT has Klipsch R-12SW 12" for $185. Yeah, it does not have the same spec's but...🙄 Muddster, it's a crap shoot either way, and neither option is cheap. How's your luck? There's also this possibility. Good luck! 1 Quote Link to comment Share on other sites More sharing options...

StarRider Posted February 19, 2022 Share Posted February 19, 2022 Hi - Currently selling a Klipsch RT-12 unit that works except it has 1 bad passive radiator cone (these can be purchased for about $125) which creates rattle and buzz, and the grills are not in great shape. Otherwise, a great unit. List on eBay as of 2/18/2022. Quote Link to comment Share on other sites More sharing options...
