"Subwoofer Speaker for your Home Theater"
The auditory range of the human ear, when measured in frequencies, lies between 20 and 20,000 Hertz, represented as Hz.

Measuring sound intensity, the human audible range lies between 0 and 120 decibels. Typically, home theater speaker subwoofer systems come fitted with different drivers with different sensitivities.
For a maximum enjoyment of music or any audio visual material, sound plays a major role and without subwoofers, a whisper or any of the low frequency sounds would be lost, but for the subwoofer which is now a standard part of any home theater speaker setup.
Home theater subwoofers, are highly sensitive and amplify low frequency sounds between 1 to 100 or 200 Hz. The use of subwoofers in home theater systems are made possible by the use of a device called a crossover which divides the audio signal frequency spectrum into separate bands, categorizing them on the basis of their frequencies.
This allows for selectively reproducing particular frequency bands through individual speaker drivers like subwoofers, main speakers and tweeters, with the subwoofers and tweeters producing the lowest and the highest frequencies respectively. Home theater speaker location is always crucial for achieving maximum music experience and depends to a large extent on room dimensions and absorption coefficients of the walls.
Of late, software is now available that allows room specifications and dimensions to be inputted that in turn generates an output prescribing home theater speaker locations in the particular room for optimal performance.
