No, a 200w speaker is not twice as loud as a 100w speaker. The perceived loudness of a speaker is measured in decibels (dB), and a 100w increase in power corresponds to an approximately 3dB increase in volume. Therefore, a 200w speaker would be approximately 3dB louder than a 100w speaker. However, an increase of 3dB is only perceived as a 100% increase in volume when the original volume is at or below 30dB ( quiet whisper).
