I have old Energy V-S surround speakers (beautiful-looking and fairly expensive) mounted high on the back wall. They never produced much sound but I guess I wasn't paying attention... recently I got a UMIK-1 and REW and measured their room response. Do you have any idea what could be causing such a steep rolloff in the treble? They actually have a knob for gain on each speaker, and this graph is with the knob turned all the way to the right. The mid position on the knob produced a graph with a much steeper rolloff.
It's not tweeter dispersion, because I measured them at different room locations with the same result. It's not one speaker's blown tweeter, because, as you can see, both exhibit the same behaviour.
Any clues as to what's going on, and how to fix it? TIA.
