Passive frequency compensation networks are disclosed which extend and smooth the base response of loudspeakers. The compensation networks include a series resonant circuit including a resistor, inductor and capacitor with the voice coil of the loudspeaker connected in parallel with the resistor and inductor. In another embodiment of the invention, a second inductor is loosely coupled to the first inductor to create a tuned transformer which eliminates ripples in the mid base response of the speaker.
