I tried unsuccessfully to search the forums for an answer so...curiosity question about the auto-on switch on my Hsu VTF2-MK5s, driven by a Pioneer SC-LX501:
Both subs are set auto-on, manual volume settings on each at 9 o'clock position. Listening to music, average 60db at the LP, Hsu #1 will turn on without issue but, invariably, #2 doesn't turn on until I add more juice (at about 65db). I thought it was just a Y-splitter in the Pioneer, meaning the same signal should be going to both. Why aren't they both responding identically?
Nothing wrong with the subs' performance; when they're on, they're fabulous.
