Subwoofer switch

I always leave all my equipment on 24/7 except when I'm gone more than a day. It will not hurt anything and is actually better for most equipment. The exception being tube equipment. It's the power surge, the rush of power when a component is first turned on that is hard on things. Ever notice that a light bulb will most always burn out right when you flip the switch on? A lot equipment will go into standby mode after a period of inactivity including subs. I would not worry about it. You can always check the manual see what the manufacturer says about it.
Happy new year to you!

Subwoofers are designed to stay powered ‘ON’ 24/7.  What are your concerns with leaving your sub ON - 24/7? 
In any case, you can use the following on/off switch for easy reach,

I leave mine on unless I'm disconnecting a cable or something. 

My reason is unnecessary power consumption. It has no standby function, not to my knowledge at least.

You can use a wireless control or a WIFI smart plug outlet:

Leave it on 24/7. If it helps, you can rationalize it by telling yourself the extra power consumption is increasing CO2. Geologically speaking the planet is near the lowest its ever been. The higher the CO2 the faster plants grow and the less water they use. So do your part to save the planet: leave it on.

@imhififan looks interesting. Thank you.

Thank you for the responses. I can surmise from the design of the sub woofer that it is meant to stay on all the time. 

Cheers,

Hello again.

I thought some of you may be interested in the reply I got from REL.

When the 7Ti subwoofer is not receiving any signal from the amp. In other words, it is "idle". It consumes 7.2 watts.

At 25 cents per KWh it comes to $15 a year to keep it on idle 24/7.

Regards,
