Hi,

I have a digital clock radio with a 2" 0.5 watt, 8 ohm speaker.
The issue is the digital radio volume at the lowest setting is too loud. I am considering replacing the speaker with a lower wattage speaker, say 0.2 watts. I know very little about how circuit boards work. Which of the two scenarios is likely after replacement:
A. The smaller speaker pulls 0.2 watts max, resulting in lower current pushed to the speaker, or...
B. The circuit board continues to push enough current to power a 0.5W speaker, creating issues for the smaller wattage speaker. In this case, would I need to install a capacitor as an additional step to reduce current to the lower-power speaker?
My other option is to leave the original speaker in and simply put in an ohm capacitor.
Right now, the lowest volume setting output is equivalent to normal speaking volume, guessing in neighborhood of 60 decibels. I want to reduce it to around whisper level, guessing around 20 decibels. So I want to reduce decibels by 1/2 to 2/3.

Any help will be apprecited.

I didn't find the right solution from the Internet.
