Bad Cornwall IV?

Hi guys. I finally upgraded my decades old receiver to an Anthem MRX-1140 to compliment my Cornwall IVs that I bought a few months ago. While running through the room correction ARC software the right front speaker sounds very different from the left and center (all Cornwall IVs). Can someone look at this graph and let me know if the speaker is bad or what the problem could be?

Thanks in advance!

PLOT TWIST!

 

I took off the binding posts in the back and put them back on and tightened the heck out of them with my fingers. I also played some EDM music at 25db which is LOUD (95db according to my decibel meter). I then re-did the room calibration and the right speaker is now PERFECT!

 

What the heck? Any thoughts??

You call that an upgrade?

Good to hear you solved the issue.

Just goes to demonstrate that good physical connections are just as important as everything else.

The bywire is Fake not true biwire from the Xover ,from the 5-6 pair I have rebuilt ,and connectors are lower quality gold over brass, when all quality connectors are copper,gold  far better conductivity. I have  rebuilt many Klipsch speakers the Xover parts are not even average quality ,the jumpers are NG . Get the tweeter replaced 

and then seriously consider rebuilding the internal Xover  which is a Major upgrade in sonics , crites type are ok at best you want Top quality resistors like Path audio ,

and a quality brand name capacitor.
