Thank you. I know that placement ist critical. My listening room is certainly not over-damped, and it is rather large, although I have to use the shorter side of the room for practical reasons (it is also our living room, and it is all glass on one side).If the speakers truly come to life at higher volume then they should not sound bass heavy. Sound bass heavy one reason is the panel output is weak.
Despite being bass heavy and listening carefully at the volume just when the panel comes to life. If you think panel sonics are greater compared to previous. Then you need to adjust the placement. Placement close to the corner and wall in front of the listener can make the overall sound bass heavy.
In my opinion try adjust the following:
Placement. After I felt placement was optimal with my ML hybrids. The resulting sonic in my spartan room can be described as understated bass, open clear midrange and clear dynamic treble.
Listening position.
Run them in minimum time a month. Observe improvement in panel sonic.
Listening room is not overcrowded with sound absorbers such as sofa, cushion, curtains, main carpet and small rugs.
If after adjustments the sound is still bass heavy, recommend new panels. For peace of mind namely - 5-year warranty, longevity, fault free craftsmanship recommend electrostatic industry leader, Martin Logan.
The sound seems very different to yours - OVERstated bass, recessed and not very clear midrange, slightly thin treble. And the speakers do not "disappear" at all, although this may be caused by the placement.
This can't be it...
