Sub power on "pop" is this bad?

    I've tried all the different configurations I can to avoid this, but the only method that avoid it sounds bad to me.

    The problem, when the power it turned on the powered subs pop. The level seems to vary and I'm concerned it's not good for the speakers. It doesn't seem to matter if the power is switched on before, during or after the rest of the equipment is switched on.

    The only configuration that doesn't pop requires me to leave the power to the subs on always. I don't feel comfortable doing that, it seems wasteful.

    So, is there any way to avoid the power on pop? I'd guess no. Can this popping cause damage to my subs?

    Thanks for any help!

    Last on, first off.

    Turn the sub on last, turn it off first (depending what you're doing).

    Ned, I've tried that (or at least the last on part) and the pop seems unavoidable. I'm just hoping it's not going to damage anything.

    Personally I just leave everything on all the time. I don't think the gear uses much juice when idle.

    Jeff.

    I gather this is a self-powered sub? (built in amp and x-over)

    And even all by itself (nothing connected to it) it pops upon turn-on. Right?

    What brand and model sub is it?

    Has it always done it or did it just start doing it?

    I believe it's always done this. It's the powered sub part of my Boston Acoustic's 970s.

    I think it has happened all the time since I've switched to using a switched power supply. Either the SurgeMaster and now a Monster Power 5000. I've tried plugging the sub power into the amp's switched outlets and the monster power outlets. On the Monster I've tried delayed and undelayed. All three of those cause the pop. The only on that doesn't is if I connect to an unswitched (always on) outlet.

    My concern about leaving the thing on all the time isn't really the power drain, although in CA every bit seems important. I'm more concerned about burning it out.

    I know with my Sub, if it doesn't recieve a signal within 40 minutes, it puts itself in standby, and the only power being used there is for a red LED, just to show that it is actually in standby.

    I am confused here. You have switched power supplies on the subs amp? Somehow I think you mean something else. Do you mean since you installed switched outlets?

    You won't burn it out and although I understand your concerns about energy usage, keep in mind that at idle the power consumtion is small. But it sounds to me like the turn-on muting circuit of the sub (if any) is not working. The only fix then would be to leave it on or have it repaired as there is no way of circumventing this externally.

    You shouldn't have to worry about power consumption... the little clock on your stove or microwave probably uses more power than the idle sub.
