"Sherwood America Home Theater Speaker Reviews"
Home theater speakers are classified into two categories, i.e electrostatic and electrodynamic.

However, assuming output and other quality parameter compatibility between the music system and the home theater speakers, the efficacy of home theater speakers is measured by its sensitivity to sound. Sound, which is basically compression waves, is created when some form of force is applied to generate these waves which travel to the ear creating the sense of sound.
In producing or otherwise amplifying sound, home theater speaker manufactures review use an application of Flemings law in producing speakers with the electrostatic speakers being made by placing a thin flat diaphragm, impregnated with a conductive material, between electrically conductive grids.
When electricity is passed through the grids, a magnetic field is created, with the resultant mechanical force generated which causes the diaphragm to vibrate resulting in the generation of sound waves. Electrodynamic home theater speakers, however, use resonance in addition to the above principle, with the sound being the result of resonance or sympathetic vibration caused in the cone or diaphragm as a result of the vibrations originating in the voice coil. Sound is generally measured in decibels, though the output of speakers is measured by an absolute measure, i.e joules per meter square, otherwise termed as watts.
In deciding on a particular brand, home theater speaker reviews prove helpful. Besides output, a credible home theater speaker review will address speaker capabilities with respect to woofer and tweeter sensitivities, besides measuring or highlighting capabilities of the speaker and its features and or compatibilities. With respect to amplifier cable impedance, crossover frequency, cutout size, dimension dispersion, frequency range, harmonic distortion, filters, power handling, cabinet diffraction etc.
