I have a pair of KEF R500s and I find that when I use the bungs (in any configuration) to tame the bass a little, it affects the treble.
I thought the ports connected to the bass drivers only and should have no impact on the treble. However, I find that when I use the the bungs they take the life and sparkle out of the top end as well as having the intended effect of reducing bass weight.
Has anyone else found this to the case?
Does anyone know why this happens or am I alone in this experience?
