Speakers Necessity in Our Lives

The backbone of every common sound system is speakers as they carry ultimate quality of sound. The best ever recording, encoded on advanced storage device and also played by best ever deck and amplifier, will not sound good if the system is linked up to poor speakers.
The speaker system is one that can take up any electronic signal stored on CDs, tapes and DVDs and easily turns them back into actual sound that we can hear. Watch this video as it gives a thorough insight into the origin of speakers and how useful they are in our day to day lives. They are very much used in cars as well and hence car speakers are in demand.
A speaker's sensitivity measures the relationship between the input power and the output sound. Sensitivity describes in fact how high the amplifier volume has to be to make the speakers work and give their best.  The sensitivity of speaker is always measured in decibels which is watt/meter. The sound signal after passing through the amplifiers propagates towards speakers.
