I thaught you were looking at that.

The amp may still be sloped correctly but the lenth of the cable and the thickness of it determines the outcome at the house.

For example the 411 frequency may be 15db on a tap and 691 shoukd be higher say 20db. After 60m or so at the end of he drop you find that 411 is 4db but 691 is 0db.

So if the op above is close to the amp then the highest frequencies should be higher than the low as that's the way the amp is set up and the cable isn't long enough to even them out.

Anyway it's 0.5db and it will be playing no part in the issue
