I have 15 year old Quad speakers which have been performing stellar, however right from initial days I always felt one speaker is slightly brighter than the other.
Recently I did REW measurement using my laptop and inbuilt microphone. Yeah, it might not be calibrated microphone - but then any coloration of microphone's frequency response will cancel out when I take difference between left and right speaker readings.
What came out confirms my ears - there is a slight difference in the frequency band from 2.8 kHz to 7 kHz. Peaking between 4.5 and 6 kHz.
What could be causing this? What could be possible solution?
Right now I am running an EQ (pulse effects) on my PC to correct for this.
