PROBLEM TO BE SOLVED: To improve the reproduction of audio frequencies, in particular, in relation to loudspeaker, to provide methods of improving the reproduction of sound for very low, low, middle and higher frequencies, and reducing the relative enclosure dimensions. SOLUTION: The loudspeaker with an embedded sound enhancement module, includes: a magnet; a pole piece positioned within the magnet; a sleeve surrounding the pole piece; a conductive wire coil wound around the sleeve between the magnet and the pole piece; a dust cap or diaphragm attached to a circumference of the sleeve; a speaker cone surrounding the dust cup; and an enclosed chamber, which has an aperture to access an internal volume of the chamber and an alternative density transmission medium (ADTM) positioned within a portion of the internal volume.
