F113v2 unexplained volume change
2 channel system with 2x F113v2, left and right of speakers. Noticed a few months ago the bass level increased so much I had to turn down the low output levels by about -4 dB in my McIntosh MEN220. Last night took the covers off and played JL Audio's Qobuz playlist. Noticed the left sub was MUCH more active than the right sub. The left sub was playing louder and the right sub was playing but quieter and less excursion. I switched the output interconnects from the MEN220 to see if the increased volume and activity then went to the right sub. It did not. The left sub was still more active and higher volume. On both subs the volume knob has been at about 10:30 on the dial. I returned the MEN220 to default level output and then I turned the left sub volume level to about 9:00 on the dial and they both seem about equal volume again. What is going on that the left sub for no reason became much more active than the right sub and at a higher volume? At first I thought the issue was with the right sub (still could be) being less active and quieter but I recalled the increased bass in the room so I am thinking the left sub has an issue. I sent an email to JL Audio. Thanks,, Jim
