Wanted:
IC: Someone to repair my Promedia 4.1

Willing to Offer: $45

I am curious to see if anyone can repair my promedia amp. Currently, the bass response is very fuzzy, and it sounds like a resistor is blown. All the speakers still work, but any bass response comes out as static, rather than the normal sound. 

 

If no one can repair it, I have 4x klipsch promedia satelites for sale.

 

Thanks

Sadly it sounds like you have blown the woofer.....normally with that type amp if you blow the amp you will short the output and blow a fuse. It is possible a resistor may have gone causing the bias voltage to be out os spec but unlikely. The woofer can be checked by removing the amp and then the woofer. Push on the woofer cone and if you feel resistance and here a scraping sound you have overheated the voice coil and made it expand. A replacement can be bought but not knowing the specs of the original I could not recommend one....good luck! I may be interested in 2 of your sattelties if you can't fix the amp

It's probably the amp that has given out. I had an issue with my 5.1 Ultra and had it sent back to Klipsch for repair (I think they charged me $80 at the time) because I had issues with the satellites. After a lot of reading, it seems that the BASH amp in the Promedia often have problems from over heating. I would suggest contacting Klipsch and see if they will still repair the 4.1 or you can also contact stpeteshepherd on ebay as he repairs Klipsch Promedia amps and does cooling upgrades.

Thanks for the responses. Unfortunately, Klipsch does not cover the 4.1 promedia speakers any longer. I will contact stpeteshepard, and hopefully all will be well. Otherwise, how much do the satellites usually sell for?

Put an ohm meter up to the speaker and check the impedance

Any interest in selling the broken unit?
