SL speakers don’t have a on/off switch. It is ok to leave the speakers plugged in all the time? What has been your experience? Dr. West says it is ok to leave it on.March 23, 2020 at 11:33 am #317TWBModerator
There is absolutely no reason to not leave them on 24/7/365 with the exception of lightening storms. If you plan to be away for an an extended period of time, perhaps. Personally, living where lightening is a rarity, I never unplug either of my two pair. Current draw in minuscule, so no reason there either. Why would you doubt Dr, West?March 23, 2020 at 5:38 pm #318operaman58Participant
My understanding is that a high voltage is maintained across the stators; would this ultimately result in the breakdown of the membrane?
I have the speakers plugged into wall outlets via remote controlled switches
My habit is to turn on the system (cd player, preamp, amp , speakers) remotely ( they are all connected to a couple of powestrips in turn plugged into a couple of wall outlets) only when listening
On weekends that may mean turning the whole system on and off 3-4 times!
I’m wondering if the stress on the electronics of turning the system on repeatedly can damage the components over the long term
When the left side amp powers on I do hear a soft thump from the left speaker; incidentally the left backplate had to have the bias replaced last yearMarch 23, 2020 at 8:11 pm #319TWBModerator
Turning any gear (with the exception of class A amps which draw considerable power in standby) off and on repeatedly is not a good idea. IMO, the stress on the components (the downside) is greater than the upside. I turn my amps off and on every night, and leave everything else powered up all the time.
Unless the bias is set too high, and there is a pinging sound coming from the speakers, there is no reason to worry about the membrane.

I turn off the bias when not listening. That’s what I’ve done with the A-1PX panels I’ve owned since January 2012 (8+ years) and I’ve experienced no breakdown issues. Prior to the A-1PXs, I owned two different versions of M-1s and M-3s (pre and post ~2006 insulation) which I left bias-on 24/7. Both eventually had breakdown issues. Perhaps my breakdown issues were simply bad luck and had nothing to do with 24/7 bias … but my luck has been better by turning off the bias when not in use.
