I am using quite old vintage AT1 speakers from PE Leon. These are two ways bass reflex floorstand speakers and I am quite happy with them. However, one of the tweaters has been damaged by a chair and is a little bit disformed. Probably due to this, I noticed with Audiolense a drop in frequency response above 13 khz on one channel that is not corrected by the RC filter. Strange is that this drop does not seem to have an impact on soundstage integrity without RC. Without RC, I have the most realistic image when my head is let say at 30 cm from the back wall. Unfortunately, I did last measurements further from the wall and this might be why the result is not that good with RC. Another strange result is that I get a delay of 1.6 ms between channels. Given this corresponds to a distance of 0.5m at the speed of sound, I suspect difference in mic distance from each speaker is not the main cause of the delay. Can phase shift between channels due to wrong mic orientation be the cause? Again, if I have a good soundstage without RC, wouldn't it be better not to compensate for the delay? I will give it a try. -- evdplancke ------------------------------------------------------------------------ evdplancke's Profile: http://forums.slimdevices.com/member.php?userid=43147 View this thread: http://forums.slimdevices.com/showthread.php?t=93393 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
