Woofer of my front speaker sounds stronger than my other front speaker. I need help !

[dazkyl]

So basically , I got a room issue with my Left and Right front speakers. My fronts are the JAMO S608 which are powered with a 10'' woofer. My AVR crossover is at 100hz. I noticed that the bass coming out from the right front speaker woofer is tighter and more stronger than the woofer of the left front speaker. Fronts are set to ''0dB'' from the AVR (Everything measured with SPL meter).

Unfortunately , I had to set the right speaker to ''-4dB'' so that the bass from the woofers is equal. Bass from woofers are now equal , but the volume of the speakers are now one higher than the other (0dB vs -4dB).

I feel like the right side of the room is filled with bass coming out from the right front speaker woofer , and the other side of the room is emptied.

Subwoofer position is great.

Obviously , this is a room issue , as my right speaker is near my computer desk and about 1 meter away from a side corner. Even the left speaker is about 1 meter away from the side corner , but that side in wide opened , as viewed later on on the picture im going to post of my setup.

Anything I can do to even the bass output from the woofers of my front speakers ?

I will not be able to move my computer desk because lack of space and wiring problem.

Thanks !

I can't quite tell from the picture you posted, where is your sub located? For me, 100 hz is high enough that I can pick out directional sound. If your sub is on the right hand side of your room, you may be associating some of its higher bass frequencies with the right front speaker. One thing I would try is lowering the crossover point on your AVR. I don't know much about those Jamos but if they each have a 10" powered woofer they sure as hell better be able to dip down to at least the 60 hz range. Lower the AVR crossover point to at or below 80 hz and see how it sounds.

If that doesn't fix it, you might consider installing a bass trap in the right hand corner of the room to absorb some of the lower frequencies and prevent them from being over amplified by the walls and corner.

Hello, sometimes when your speakers are not in phase, then the woofers can experience what you may be hearing. Check the polarity of your speakers wires to your amp to make sure that they are correct.

Also, if you have other 2 speakers, try it in the same location and if it is the same, then maybe it's your room but otherwise recheck the polarity of the wires.

The subwoofer is located behind the Christmas tree. I did like my 100hz crossover in the receiver. I thought im giving the receiver less work to do , and the bass from the subwoofer was pretty great.

Can you tell me how to check the polarity of my speaker wires please? Does different speaker wires improve the overall quality ?

What speaker wire are you using?

If your speakers are out of phase, the woofers can react this way so check the polarity by making sure the positive ends and negative ends are connected properly to your speaker and to your receiver.

In that picture from what I see, it could be difficult to tell which is positive and which is negative. Did you try other speakers to see if the room is creating one woofer stronger than the other? Because if all speakers sound this way in the way you set it up, then it could be your room.

No i did not , but im pretty sure its a problem with my room. Both woofers are working as i tested them. Neither one is stronger than the other , so its because of the room. Should i leave a little space in the corner between the right front speaker and the computer desk ? Or put the computer desk exactly in the corner ?

The wire you have is basic lampcord and there is an easy way to tell the difference between the 2 strands. As you split the wire one side should have a ridge that you can feel with your finger. It's a slight bump raised from the wire. If you attach that end to the Positive terminal of the speaker...make sure you do the same on the receiver end. If you do this you are in phase and all is good.

EDIT: Sometimes there is a colour-coded (usually white) line that runs along one of the two strands.

If your pretty sure the problem is your room, then try different speaker placements or furniture placements. Good luck.

I noticed that the wires in the right speakers were properly connected. I checked the left speaker wires and one of them was kinda of loose. I wired it properly. I will give it another try. I will check the wires on the back of my receiver. What about the question regarding the computer desc ? leave it about 70 cm from the front wall/corner or exactly in the corner?

Wiring is all fine. What about the computer desk ? Should i leave some space between it and the corner ? Or move it exactly with the front wall ?

Can you remove the Christmas Tree? I would suggest this and then move the entire system to the left.

That shot was taken in December so all decorations are removed. I can move it to the left but i cant move my center speaker as its wall mounted and if i move to the left on my seating position i will come too close near my rear left speaker.

Then you're going to have to experiment with everything, including speaker placement and the desk. We can't tell you what to do as we can't hear the outcome of the changes.
