Default On/off switch for one small stereo speaker - good idea?

Can you specialists me advise please. I want to be able to switch a
small speaker on and off.

The speaker is attached to a small stereo (approx 15W + 15W) which
has one speaker in the kitchen and one in the hallway.

Is it ok to simply put a switch in the speaker lead? I am concerned
about two things with this approach:

(a) The on/off action may cause transients which may damage the
amplifier.

(b) The lack of any load on one channel may cause the amplifier to
have a shorter life than otherwise.



Any advice gratefully received. Thank you.


most amplifiers have switches for two sets of speakers that do just that.

Lack of load shouldn't hurt a modern solid state amplifier. But if
you're concerned, switch a load of a 20 to 30 ohm, 10 watt resistor in
place of the speaker.

Only with a tube amplifier.

You could also put a 50 ohm pot in series.
