Brand new Forte IV static distortion on certain frequency.


Recommended Posts

I just purchased a pair of new Forte IV online from one of the reseller, and notice that 1 of them is producing hoarse static distortion noise around certain frequency (playing piano pieces). 


Contacted the seller, and waiting for the reply. 


But very disappointing that a brand new pair has this issue from klipsch, QC should have caught it.

The brand new pair of original-series Fortes I unboxed myself back in 1988 had a midrange blown - I could tell from vocals, mainly female, which provided a bit of a static rattle, if my acoustic memory serves.

I loaded it up and took it back to the showroom, where they swapped out the mid horn with one in a model they knew worked just fine.


It's still running sweet, some 34 years later.
Hopefully, you can be back up and running with it soon...

It was the K702, the diaphragm was defective. The reseller sent me another and its now singing  beautifully. I can see the Forte staying for very long time.....

Did they send you a new  driver , or just the  diaphragm

They sent me the whole new driver. I believe only klipsch or the oem factory can redo the diaphragm. I tested with all the genres from spotify I can think of, and it's good now. And yes, forte iv sounding life-like and awesome. I'm using it as main instead of my usual sopra to break-in as well as hooking up my dual rythmik F12Gs to it for the 20-50 region.


Would love to find the schematic for the crossover and see if they can be upgraded in the future.
