I have a Yamaha receiver in which when I test the sound one of the speakers (front right) is quieter than the others. I've tried the obvious troubleshooting: new wire, new speaker (no matter what the front right is the quiet one), moving to channel B. Same results. What could be the problem?

what model is it? does it have discrete channel adjustments (ie +/- dB levels)?

It's an HTR-5240 (about 8 years old). As far as I could tell the levels of all the speakers were set the same.

A speaker can be quieter if:

- it's in the open when the others are in a corner
- it's got something wrong with it.

A "location" can be quieter if the AVR has not been tuned to compensate for a specific location - most AVRs allow you to boost or cut each location, although the main speakers may not have that feature.

It looks like you tried swapping the LF & RF speakers to see if the same speaker is still quieter. Since the RF location (not the actual speaker) is still quieter, then the AVR setup may allow you to increase the sound level of the RF? Try that.

Also, have you checked your "balance" setting - it could have been moved towards the left side? There could be something wrong with the amp, but you could test that by putting the LF and RF speakers in the same spot (say out in the open) and hearing if one is still louder than the other - especially useful if you have an SPL meter to check.

For example,
My left speaker is set to +4(a corner)my right is set to +6.5,the door entrance to the room is there.
Sometimes even windows can screw with volumes of the speakers.It's a very common thing

Thanks for your help. Apparently the solution was an easy one that I was overlooking. My 2-year old son turned the balance knob. I was racking my idiot brain trying to figure this out and it took one second to fix it. Thanks 57.

Ozzman, in response to your comment, how did you arrive at those settings? Did you just adjust it by ear or was there some specific way of adjusting those settings?

Glad to be of service. Check out the following post, useful for those new to the forum:

You can certainly adjust by ear, but an SPL meter is usually better if you can borrow or purchase one.

I used my mic setup.

Then adjusted to my liking.Every time i used the mic setup my right front was always higher then my left,It did`t bother me because it makes sense(the entrance is there like i said)

My center is always lower then my fronts,but this is something i already knew.may i suggest,You don`t want your center set louder then your fronts.

my rears are lower then my fronts and center and my back surrounds are just +2 louder then my rears,But i have large rears(PSB 800i)there not bookshelves.

Everybody`s setup is different because of there room ,the speakers you use and the placement of your speakers,But i just wanted to give you an idea where i am with MY set up .I hope this helps you
