Robin,
Actually, I think my system goes fairly low as it is. I haven't put an SPL meter on it yet, but I think it's safe to say that it's no more than 3db down at 60Hz. Maybe 50Hz. (I'll find out for sure with a meter before I proceed too much further.) (I'm looking for that extra octave with the sub.) I was under the impression that it was not acceptable to sum the channels with a Y-connector because you mess up the impedance. Is this not true? -- jonheal Jon Heal says: Have a nice day! http://www.theheals.org/ ------------------------------------------------------------------------ jonheal's Profile: http://forums.slimdevices.com/member.php?userid=2133 View this thread: http://forums.slimdevices.com/showthread.php?t=20907 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
