Right front speaker sounds higher and brighter than the left front speaker.

[dazkyl]

So basically i got a problem with my left and right front speakers. The right speaker , which is on the side of the room that is closed and with furniture , sounds brighter and higher than the left speaker , which is on the other side of the room and this side is wide opened.

Both are set at ''+1dB'' from AVR via SPL METER.

Any thing i can do to fix this issue apart from setting the left speaker higher ''dB'' than the other one ?

This is a shot of my setup.
