A good loudspeaker performance is a high correlation of listener preferences with high-resolution measurements of on-axis and off-axis magnitude response. Also with a wide bandwidth, flat and smooth magnitude response, and uniformly wide dispersion factor.

In order to achieve many of these desirable design features, computer-aided design of loudspeaker systems has become an important tool in the loudspeaker designer's daily work.

Certain transducers, usually used as a low frequency source that employs a moving-coil magnetoelectricity structure(in the 10 to 1000 Hz frequency region). Innovations of FINEMotor over the moving-coil transducer units include design improvements for SPL,T/S, coil parameters, optimized heat dissipation, increased moving-coil copper density, more rugged construction, and stiffer laminated stainless steel and epoxy piston dome.

FINEMotor and FINECone are routinely used by the world's larger loudspeaker companies in an effort to control the many complex parameters that affect the performance of a complete loudspeaker system.
