Hi Forum,
now that the aches with my Sequels were solved in no time at all through ONE post on this forum (how much more efficient can you get - thanks to you Forum guys), on to the next problem area, one of my CLS II panels.
I am listening to the CLS IIs for about 6 months now and notice ever so often (I know this is vague but I have not been able to ascertain any pattern or specific situation yet) that one and the same panel goes down in loudness by about 70% (estimate) after about something like 20 minutes playing. I reversed the cables to the other stereo channel, have used four different power amplifiers (from low 80 W output to way beyond the panels capacity), all the same. I turn them off, after some time (hours to a day, not minutes) I turn on the power again, the panels sound equally loud. Then, same game again, my left panel goes "dim" but not after the same time as before. It is also independent of the music and loudness I play them at.
I have vacuumed them, have not had them under the shower yet but they do not look dirty.
What I have not done yet is switch the electrics boxes from one panel to the other. Will do that next.
When they play with equal loudness, they sound great (yes, I have read all the bass threads!! More than interesting - fascinating). They also still sound great when the one panel goes down in loudness. It plays all across the panel all the time; no dead areas. I slide my ears across and up and down. Given enough amps in the amplifier, I can get them to sound equally loud by using the power output knob for the weak channel but I do not feel comfortable doing that. The left panel remains at that low output level then, it does not get any weaker even after many hours playing.
My CLS IIs are used in a quadrophonic system as front speakers with two Aerius as rear speakers in a Swiss wooden "barn" from 1837 in its 40' x 22' A-frame attic. I use spikes on a granite plate under the CLS IIs, mainly listen to classical music, and, yes, am thinking about a subwoofer setup. When I added the Aerius as rear speakers, the bass question was helped a bit.
Does anyone have an idea what could be the problem with the CLS II panel going down in loudness level?
Thanks folks,
Arthur
