Speakers radiate their sound in an angle that becomes narrower and narrower as the sound frequency becomes higher. Therefore, a tweeter is very directional, and a bass woofer is very non-directional.   Back   Back   Home  |  Contact Us  |  About Us  |  Advertise  |  Car Audio How to Links  |  Join!  |  Log-In

The sound deadening (absorptive) characteristics of any substance. The reference unit of absorption is one sabine which is equal to the sound "absorbed" by a one square foot opening through which sound passes (open hole).   Back   Back   Home  |  Contact Us  |  About Us  |  Advertise  |  Car Audio How to Links  |  Join!  |  Log-In [..]

A device which increases the level of a signal (by increasing the voltage or current}. Some amplifiers are used to isolate or control a signal, and may not increase level -or may actually decrease the level (line out converter, head amp}.   Back   Back   Home  |  Contact Us  |  About Us  |  Advertise  |  Car Audio How to Links  |  Join!  |  Log-In [..]

An amplifier which is designed for driving loudspeakers and consequently has higher power output capability than a line amplifier or preamplifier.   Back   Back   Home  |  Contact Us  |  About Us  |  Advertise  |  Car Audio How to Links  |  Join!  |  Log-In

An electrical signal whose frequency and level vary continuously in direct relationship to the original acoustical sound waves. "analog" also may refer to a control or circuit which continuously changes the level of a signal in a direct relationship to the control setting.   Back   Back   Home  |  Contact Us  |  About Us  |  Advertise  |  [..]
