A speaker driver with a high degree of symmetry for use in a loudspeaker is disclosed. The disclosed motor assembly may be symmetrical about its long and radial axes. A voice coil disclosed may be supported by opposing upper and lower suspension members on the voice coil upper and lower ends. The upper and lower voice coil suspension members disclosed may be adhered to a frame above and below the motor assembly, respectively in a mirror like fashion being symmetrical about their long and radial axes. An open voice coil frame disclosed may use elongate structural members having a shape similar to the letter “j” (j-beams) defining large interconnected air gaps to promote cooling of the voice coil.
