It would appear YPAO has damaged my speakers

[NM88]

Hello everyone, I’m kind of at a loss here. I just added a Klipsch subwoofer to my setup to complete my 2.1 set up. Not knowing that it’s basically totally worthless to run YPAO with a 2.1 setup, I ran it. After it was complete, I immediately went to jam some music and noticed the music sounded distorted. Turned it up more, and yep, definitely was distorted and sounded terrible. So I go to see what YPAO had set my speakers to. For some reason, it had set my front speakers to LARGE and turned the db on both to +10. I immediately set everything back to normal but now the front speakers sound...blown? They sound muddy or fuzzy, definitely not as clear they were. Did the YPAO just destroy my speakers? If it helps, here is my set up

It is impossible to say from what you wrote. Did the speakers suddenly play really loud after calibration? Did YPAO add some odd Eq after you ran it? In any case what I would do is do a reset back to default and start again with no YPAO. If it is distorted after than, then I suspect somehow your speakers have been damaged, but it could be the receiver also.

Yes, they played absurdly loud after the calibration.
The only thing I really looked at after the calibration was the db level, which had been set +10 on both front speakers. After that I just panicked and reset everything.

The receiver could have been damaged. Have you tried the speakers with another amplifier to be sure it was the speakers?

Unfortunately I don’t have another amp to test it with .

From what you say you most likely have blown your speakers. It could however be your receiver that got damaged, but my inclination is that it is more likely your speakers by far. Have you put your ear close to each driver in turn to see if any in particular are not working at all or sound rough?

You really should have checked what YPAO before playing anything.

 

[NM88]

I mean, I didn’t check the levels because it never crossed my mind that YPAO could cause catastrophic damage.

While YPAO isn't likely damaging anything without your help on the master volume dial.. and turning it up more when already sounding bad....

With a 2.1 setup YPAO might set levels between speaker sub and apply some eq....and seems if it needed to turn your speakers up so much it is indicating your sub gain is set too high perhaps...

Maybe you blew the tweets but maybe not but need more info....

The receiver wouldn't do anything to the main level control, just tailor the output to whatever was measured. If the receiver had been operating at max volume before the test, it may have returned to that when the music started, but that's not YPAO's fault.

Sounds like a volume control issue. Not YPAO.

The volume was at -60 db before the test and was at that after. I turned it up to -40 after the test. I never turned it past -40 db once the distortion started.

Speakers would never die at -40dB and the receiver would shut off if DC voltage hit the protection circuit.

Do a hard reset and, if possible, try it with a different speaker and connect the speakers to another amplifier- that's the only way you'll find where the problem lies.

I probably should have stated this in the original post, but I never turned the volume to an absurd level. I had it set to -60db before I ran YPAO and then turned it to -40db after. I may have very briefly turned into it -30 but I don’t think I did.

None of those volume levels sound like speaker-damaging potential.

 

[Pogre]

Even with the +10 dB boost those aren't anywhere near speaker busting levels.

Usually to bLow a woofer you need to exceed Xmax I did it once with a low end amp I later returned... turns out the wire to the voice coil was torn I just reconnected it and it worked .
Lots of distortion or massive wattage can also but not likely during ypao.
I got two pairs of replacement woofers essentially for nothing. Not even using my realistic speakers or my rtr anymore .

I’ve not used ypao before but with my onkyo the audysee is same volume no matter what . Just don’t let the sub decibels go over 75.... during setup .

An easy test is to hit the pure direct button and tell us if you still hear distortion coming from the speakers. Also please check your connections at the speakers and at the receiver to make sure you dont have any shorts between the terminals.
