You're close, very close. The "signal" in the speaker cable is an alternating current and voltage that causes the speaker diaphragm to move back and forth. When current goes through a voice coil it produces a magnetic field that moves the diaphragm one direction or the other depending on which direction the current is moving through the + and - connections at that instant.. The instantaneous rate of alternating current is approximately 20 Hz to 20,000 Hz. The "signal" in the cable doesn't contain frequencies. The instantaneous frequency of the acoustic signal/waveform coming out of the speakers is derived from the rate that current and voltage in the cable is alternating at that instant.
