weird problem with my JBL LSR2325P monitors

| I have a very frustrating problem... I have a pair of JBL LSR2325P monitors and recently discovered, much to my horror, that the audio coming out of the right monitor had substantially less low-end than the left one. I conclusively figured this out after panning a bass synth hard left which was a comparatively heavier sound than when I panned it hard right, which was much thinner. needless to say this is pissing me off because I have no idea why this is happening or what's causing it. Has this kind of problem happened to anyone else, and are there any good resources and information to start with to fix this? thanks guys |

| Maybe you have some room control buttons on the back? Check them so their at equal value. |

| Also check the location of each monitor. Placement in your room can have a considerable effect on the frequency response, particularly in the lows. Try swapping them around and see if the problem persists. |

fuxzz: Yea, I did check the knobs in the back... the volume knobs are in the same position and the eq stuff is turned off.
aquila: alright, I'll try this when I have time. My set-up is in the corner of my room... if I have one monitor huddled against the corner and the other is against the wall, would this make a difference? |

It could most certainly be the problem in terms of perceived level at a particular listening point but it's going to be a really easy test to confirm if this is the issue; just put the speakers right next to each other and pan left and right.
The other thing it could be is cable related; if one is balanced and the other not (or short circuited) that could cause a frequency/volume related problem. Switch the cables and see what happens.
I actually own these monitors and there should not be any issues like this.
If it's neither of these things than you may have a faulty crossover but the good news is that JBL are really helpful with these things. |

| I would use test tones for the moment so you are not distracted confounds. If you have access to a microphone, place them on the same stand alternatly using the same cable and then another cable. The room is generally notg an issue for mid lows which im guessing is what you mean by low end. |

bingo!
corners=bad!
walls too really.
1m in every direction is prefered :) |

| Wont affect your perception of direction for low end unless you are really close to the speaker but that doesnt seem to be the case. Take the room out of the equation and place the speakers in the same spot. |

It will actually; placing a speaker too close to a wall, especially a rear ported one as in this case, will make the speaker sound louder in terms of low frequency, and as you know, volume and it's relation in the stereo field is one part of our ability to discern direction.
The closer you get to true sub, the less it is crucial, but these speakers only just go down to 80hz so when the OP is talking about bass he's also talking about low mids, which are affected. |

| i think the problem is that he hasn't really defined what he means by bass or low end, how far he is from the speakers and how big of a difference and I suppose how big the room is. I just find it rather unlikely that the room is the culprit especially if it is occurring at the normal listening position. Unless it is mid lows as I previously mentioned. I guess that is perhaps why he should test using pure tones rather than audio that could have a wide spectrum. |

Very true. I have a feeling it's low mids as the speakers don't really do that much LF in the true sense. I could be the rooms but as you say, he'd be able to tell in a 2 minute test by putter the speakers next to each other, away from any walls. |

| sorry guys for the late reply, been busy recently with school and stuff... don't get me wrong this is really helpful. I will find some time to try some of these tips, and possibly upload a picture of how they are set-up |
