    I have a Mordaunt Short 308 subwoofer. Everytime I turn off the power the subwoofer makes a strange noise ("boom"). Is that normal?

    Well, perhaps not normal but it may happen. Switch off the sub first and then the AC mains if you have used the latter only, this may help.

    Unless you can't afford the electricty then leave your sub on at all times. It will cause less wear to the elctronics and sound better because it will be warm at all times.

    Retro is right , just leave it on at all times, as he mentions .

    Some subs have a power save , if a signal is not detected over a period of time then it automatically switches off , then back on accordingly.

    The noise that you hear is the fluctuation in electrical supply on switching , which is amplified by the sub , and is normal .

    If you can leave it switched on , i do !!!

    Everybody has he/she likes but leaving the sub on all the time may increase the risk of fire even if it's in standby mode (and even though the risk is minimal), so keep in mind to switch it off if you are not at home for a longer time.

    The boom is not normal as I would expect all modern electronics to have a delay circuit avoiding this (as most AV amps/receivers do).

    I don´t know if it is normal, but my subs, REL Strata III also do that when I switch them on, I just leave them on all the time...

    Its best to leave most of your electronics on all the time. The highest moment of stress for any of your gear is at switch on. Not only that but everything also sounds cleaner smoother and generaly better when compaired to cold starting/playing.
    My projector is the only thing that is on standby mode when not in use.
