Abstract
An electronic audio system that determines matching and non-matching speakers is disclosed. The electronic audio system includes a first speaker; a second speaker; and a comparator circuit. The comparator circuit is coupled to the first speaker and the second speaker to receive an input signal from both the first and second speaker. The comparator circuit is configured to determine if the first speaker and the second speaker are matching speakers or non-matching speakers, in which, the first and second speakers are matching speakers if they are common vendor speakers. Other embodiments are also described and claimed.
