ABSTRACT:
A speaker that includes a pair of spaced-apart, in-plane mounted drivers connected in series to a network for applying the appropriate frequency component of the electrical input drive signal to each of the drivers is disclosed. A frequency dependent shunting network, such as a low pass filter, is applied to one of the drivers so as to gradually mute the one driver as a desired frequency is approached. The result is an aesthetically pleasing speaker that has dual in-plane drivers and that produces superior sound quality throughout the entire frequency range of the speaker, including those ranges in which dual, in plane, drivers tend to acoustically interfere with each other.
