buggered up my measurement on my bass traps!

damn! Should have applied the old measure twice, cut once rule! Once fully finished, I noticed that my traps are 2ft wide, but I forgot to take into account the frame holding the rockwool. End result, my traps are nearly a couple of inches off of 2ft of actual absorbtion area ( though they are 7ft high as a bonus :D ) Its too late, thats how they will stay, but will it noticeable detract from its effectiveness? As said, its done now, but out of curiosity, will I take a noticeable performance hit because of this? thanks

:) The only reason these traps are standard 2 ft is because the wool is that wide. If the wool should be 22" wide, traps should standard be 22".
