Specific quality or unique aspect of sound that makes it distinguishable from other sounds of the same volume and frequency. Timbre makes instruments sound different when reproducing the same frequencies for example. peakers have different timbres. For this reason, speakers to be used together should have a similar timbre. This is particularly important for center channel speakers in relation to a sound system’s main front left and right stereo speaker pair. Without a close timbre match between the center speaker and main speakers, the sound from the center will sound unnatural resulting in a poor soundstage. For instance, a plane flying across the screen might first appear in the left speaker. You will hear its sound as it roars into the acoustic space. As it crosses through the center of the soundstage the center speaker will reproduce it. If the center speaker is very different in its timbre from the other speakers it will sound like the plane changes as it passes (for instance, its engine may sound high-pitched then change to slightly muddy or lack the original high-pitched sound). In order for the sound to remain consistent and create a convincing experience, the center channel speaker should have a close timbre match to the other speakers.
