Do both of your speakers sound the same? White noise might say otherwise.

So one day I was playing with the menu on my AV receiver Oykyo TX-SR805 one of the big boys with nudes

I found a speaker level option that plays a white noise I guess you can call it that sends a tone to either left or right and I imagine you set the output so they match in volume. The part that got me was one speaker played a higher tone white noise than the other (very noticeable)

Now I am like WTH how can they sound so different? So I am like maybe because one is over there and the other is over there so I put both side to side in the middle of the room with the same outcome. Now OCD is kicking in big time as they sound the same listening to music but obviously not.

Well maybe its the output on the receiver so I switch wires on speakers and the tone difference stays the same between the two.

Ok now this is bugging the hell out of me the tone of the white noise was very different between the two.

I grab a completely different set of speakers my Allison 2 ways which have also been recapped and I get the exact same effect. They sound just like the big 12 inch 3 ways I had hooked up previously.

This left me quiet baffled as two completely different sets and style of speakers exhibited the same behavior and sounded the same.

I could let my OCD drive me crazy with this but I am not going to.

I know Onkyo products are over built
Btw they just filed for chapter 11.
You paid 100$ for it
Is it even close to a high quality
Reference stereo unit?
 
I do not understand your post as the receiver is not really the subject.

Not the point but it sounds fantastic.
 
When you say you switched the speaker leads and the "tone difference stays the same," do you mean that, for instance, the left speaker sounded a bit duller and that after switching the leads, the dullness stayed in the left speaker, or the tone difference was the same but now in the right speaker?

Have you tried, instead of swapping the leads, leaving the speakers connected to the same channels and physically swapping the location of the speakers? It's amazing just how much placement can affect the timbre of white noise/frequency response at the listening position. Even if the speakers are next to each other near the middle of the room. Is the difference still apparent at low levels when listening near-field, within one foot of each speaker on-axis?

As I noted to eliminate any difference the speakers were placed side to side in the middle of the room. The signal from receiver was the same left to right as the tone of each speaker stayed the same when I swapped wires from the left speaker to the right.

I am not even going to try and figure this out I am not sure what's up with the what I would call "white noise" signal it puts or exactly waht it is but both completely diferent sets of speakers were the same result.

Say I took the 1st speaker that played the white noise at a lower tone and put it next to the second completly different speaker that also played the same lower tone white noise and put them next to each other they would have sounded the same.

how two different sets of speakers can exhibit the same outcome with the difference in tone almost exactly the same is odd. the higher tone first speaker sounded just like the higher tone second speaker and vice versa. The higher tone speaker for instance from each set was the same tone signature not one a little higher tone than the other Higher tone but the same higher tone.

which is a million to one coincidence ( which I doubt) or something with the white noise is able to show something I cant explain.

Both sets sounds the same as its partner while listening to music but how both sets show the same difference with "white noise" was quite mind boggling.

I can understand production tolerance between two of the same speakers and that I could accept, but I am not even going to try and figure out how two completely different speakers have the almost identical tonal difference between its mate and the other set with the white noise.

There has to be some higher power going on.

Is your room asymmetrical? Acoustics can do this sort of thing.

That's a much more succinct way of stating one of the things I hypothesized earlier.
If the same phenomena are heard on two different sets of speakers, it's highly doubtful it's the speakers. It's either the amplifier (I have a Dynaco SCA80Q that had a left channel that never sounded exactly like the right channel... for over three decades... until I finally got up the nerve to tear it completely apart and discover the many issues. It's the best sounding SCA80Q I've ever heard now... ), the connections between the amp and the speakers, or the room.

Or, and I am not saying this facetiously.... your hearing. It's pretty common to have the hearing in one's ears deteriorate asymmetrically as one ages.

My intent was not to criticize your Onkyo AV Receiver. i actually think they are the best quality Bargain AV recievers on the market.
I even told my son to get one for his JBL studio 590's and his AV set-up.
I am criticizing All AV receivers for not being even close to a good Hi-Fi Rig.
What is your source of the White noise?
Most speakers especially older ones Have 10-20% tolerance Caps, Resisters that deteriorate more with time.
along with the L-pads
as well as speaker component impedance differences. all these factors will make a Noticeable difference.

Tried that, I wish.

like I said speakers were right next to each other and its just a square room speakers at the same Height not near anything and you could hear the difference 6 inches away or 8ft away.

Maybe I will try one more set of speakers I have someday.

The difference on both sets were like having the base white noise (static sound) and turning either the bass or treble up a few notches on one of them.

even though they were basically touching each other I even swapped them side to side just to rule that out to, I knew it wouldn't matter as you can hear the difference standing right in front of them but did it anyway.. Ye i even swapped wires which I knew wouldn't matter they are exactly the same length.
 
So, for each speaker pair, when you switched the location of the speakers without changing the connections, the "different" sound of, say, the left speaker stayed with that speaker when it was moved to the right speaker position, correct? That would rule out a room issue or an issue with your ears.

When you left the speakers in position without moving them, but swapped the wires so that the amp's right output was now feeding the left speaker, the "different" sound remained in the left speaker, correct? If so, that would indicate a problem with the speaker. If it happened with BOTH pairs of speakers, as unlikely as this may be, that would indicate a problem with the left speaker of BOTH pairs, and require that, coincidentally, you had placed the faulty speaker of each pair on the left side (or whatever side you hear the fault in). That's a LOT of coincidence.

I suppose, if both sets of speakers had at one time been driven by the same amp with a faulty channel (not necessarily the one you're currently using, but one in the past?) had been exposed to a lot of clipping, and been damaged the same way, it's possible, but still a VERY long shot.

Swapping wires seems easy to keep straight, as is the logic behind troubleshooting, but it's easy to get messed up. I've gotten turned around on my test bench a few times, swearing that the test I've done indicates an issue with a speaker, but then realizing that I had it backwards and that, no, the procedure DID show that the issue was with an amp channel or connection. Take your time. Maybe make a checklist as to what you change each step, and then the result.
 
It might be a good idea to go into the Onkyo surround receiver`s configuration setup menu to check for any settings that might effect any of it`s L/R inputs, outputs, etc. balance to see if any are offset from default.

You may have to connect it`s video output to a compatible display device, if not already connected, to visually check the setup menu settings..

Good luck, NH-MAN
 
i've got 7 speakers for my surround duties, same manufacturer, same tweeter, same driver compositions they all sound pretty similar(with white noise from the marantz) with the exception of the center channel, it is noticeably off. i attribute it to different batches of drivers or crossover components. i don't obsess with it, if i did then i would be listening for differences when watching a movie and not even focus on the movie itself and trust me, i have enough trouble focusing on a movie nowadays.
