Dual Voice Coil speakers are another clever option created by audio engineers that allow both the left and right channel to be played from a single speaker by placing two angled tweeters in one speaker. Dual voice Coil speakers are ideal for small or oddly shaped spaces where the balanced left and right sound would be difficult to achieve with two speakers. Dual Voice Coil speakers offer excellent sound quality and great flexibility because you don't need to worry about placing two speakers for balanced sound.
