"Center Speaker For Home Theaters"
The home theater center speakers generally reproduces the middle bands middle range frequencies.

With sound waves essentially being compression waves caused by the conversion of electrical energy into mechanical energy creating a disturbance in the air, the force applied in creating the disturbance, which travels as waves, is what impacts the amplitude of loudness of the sound produced.
With home theater center speaker channels handling the middle frequencies, maximum loudness or amplitude is achieved through maximum wattage. However, room acoustics will influence the degree of incidence of peak spots and sweet spots which reinforce amplitude at certain points, while affecting the timbre or quality of the music at the so called sweet spots.
The best center speakers will address potential timbre issues through appropriate speaker harmonics. Home theater speakers harmonics are affected by dimensions of the speaker as well as the material of speaker which vary depending upon its elasticity, density and absorption coefficients.
These factors differently affect trasmission, reflection or absorption of the sounds produced, besides impacting resonance. The inherent resonance of the speakers produce specific harmonics which affect overtones and consequently have varying degrees of timbre or sound quality.
Home thater speakers cannot be considered in isolation. Its performance is relative to the home theater speaker location with reference to the room and other specifications, which have to be modified or tuned to ensure compatibility for optimal performance.
