auto switch on subwoofers?

I have read that the auto setting on a Sony SA-CS 9 sub-woofer can be a problem in that it cuts off and on with a fairly loud clicking noise. I also understand that the problem might be corrected by turning this feature off but then the power would have to be turned off and on manually before and after each use. Is this a problem with all Subs that have an auto setting or just with this particular model? I really want to like the Sony because it matches my other core equipment and might be all I need in a 13' x 17' room.

That Sony sub looks like an updated version of the Sony SA-W2500 which I owned and just sold. I tried the AUTO setting for a while but if there isn't a sufficient amount of bass present in whatever your are listening to, it will shut off, and you hear the 'click' of the relay. I solved the problem by leaving the sub turned on all the time.

I presume the constant switching on and off in AUTO mode would be problem with all subs, but whether or not you can hear it switching off/on is another matter.

Thanks for your reply. If you leave the sub on all the time will it get too hot? How did it work for you after you stopped using the AUTO setting? Think it would be good in a smaller room and used mostly for movies?

It won't get hot because when it's idling it's barely drawing any current from the wall outlet. Once I stopped using the Auto setting I forgot all about there being a clicking problem with the sub. There were no problems.

Think of it this way--how much electrical current is a garage door opener drawing when the motor is not engaged lifting the garage door? Almost nothing--just enough to keep the radio receiver "listening" for a signal from the handheld opener and keep a couple of LED lights lit up.

It's something that I feel is common with the Auto On feature.

The Elac sub I had made a unsettling "pop" sound whenever it went into standby mode that truly sounded like it was going to damage the driver over time. I just leave the switch to the full On position because 9.9/10 it consumes the same amount of power whether it's on or just in standby. Also, I found that the sub will stop outputting any sort of signal even part-way through a song, and not start up again until I flipped the switch on then back to auto.

For ME, I prefer to set the sub power to ON. With the subs powered on during a movie. There should be less of a delay when the LFE audio signal is sent to the subwoofers. You should experience the full LFE signal event. With auto there may potentially be a delay with the subwoofers responding to the LFE signal. As subs would need to turn on (wake from sleep mode.)

You may find this helpful.

I don’t prefer to leave the subs on all the time 24/7. I use these RF controlled plug in outlets to remotely turn the subs on before enjoying a movie or concert and off when I am done enjoying a movie or concert.

I use a RF controlled plug in outlet. Plug each sub into a RF controlled outlet then plug the outlet into a wall outlet. Now when I am done enjoying a movie or concert. I turn the subs on/off with the RF controlled outlet.

Thanks for the reply. I had thought about something like this so I can turn it off when not in use.

My subs have an auto-on function that works fine, but when I noticed that the back of the subs still get a little warm to the touch while in "standby" mode, I decided to buy a pair of these...can't beat the price!

I just turn it off whenever I know I won't be using the subs again for at least a day or longer, other than just low level NPR or something like that.

~ Are you a "geek hobbyist" obsessed with squeezing out that last 5-10% improvement? The economy will thank you...especially the Chinese one. Or are you more of a get-set-and-forget "casual user" who simply wants to increase your enjoyment of movies, TV and gaming? Relax, HT isn't rocket science, nor does it have to cost an arm and a leg---especially if you ignore the aforementioned vocal minority. And remember to smile...it's just a silly hobby, after all. :)
