Answer - A - The acoustic sensitivity rating of an average speaker is 90 dB/Wm.

Key Takeaway: The acoustic sensitivity rating of a speaker is the amount of volume a speaker can produce from an input at a given power level. The sensitivity rating of a speaker is stated as db/Wm, which translates to decibels per watt of power measured at one meter (about 3.3 feet) from the speaker. 90 db/Wm is an average sensitivity rating for most speakers. A speaker with a rating of 87 or below is considered low sensitivity and a speaker with a 93 or higher rating is considered high sensitivity.
