Cabinet blemishes on the inside of the cabinet severe enough to have any effect on performance would be virtually impossible. However, that being said, if it were to happen, it would show up on our acoustical tests. 'Firsts' and 'Seconds' undergo exactly the same acoustical tests. If there is a discrepancy in sound from our reference loudspeaker, then the speaker is taken off the line and given to the engineering department for investigation. We understand that some people aren't concerned with minor cosmetic imperfections, but we're sure no one wants even the slightest defect in sound!
