That's a common misconception - bass doesn't come solely through the ports. Bass sound pressure comes from the front of the cone just as it does from the back. The rear wave is tuned by a Helmholtz resonator which loads the cone at bass frequencies, but most of the sound you hear comes from the front. Only a narrow range in the bottom octave comes through the ports.
