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 !
