1. Audio Glossary of Terms
(Technical/Definitions)

... the signal of another radio station two channels (0.4 Mhz) away. Measured in decibels, the higher the number the better.       • Alternating Current (AC) - An electric current that reverses direction ...

2. Twice as loud ? Lets talk dB's
(Technical/Theory and Physics)

Decibels, dB, are a measure of loudness. Unlike other measurements, decibels are logarithmic in scale not linear. Speed is linear, 40km/h is twice as fast 20km/h. Time is linear, 60 seconds is twice ...

3. Kicker Announces 2010 ZX Series Amplifier Models
(News/Latest)

... efficient chassis, ZX Sub Amps offer a 24dB/octave low-pass electronic crossover and a 24dB/octave, high-pass subsonic filter fixed at 25 hertz. All have up to +18 decibels of boost centered at 40 hertz, ...

4. Crossover Orders, 6 decibels of separation
(Technical/Theory and Physics)

Crossover Orders, 6 decibels of separation So whats a crossover ? Once set, it attenuates the frequencies either above it (low pass) or below it (above it). Wait that doesnt make sense you say, but it ...

6. How to use an Oscilloscope (CRO) to identify clipping
(Electronics/Car Audio Electronics)

Here's a quick & dirty intro to the CRO (Cathode Ray Oscilloscope), how to set it up properly & how to identify clipping. For this test I've used: BWD-509B CRO Digitor 707 Digital Multimeter ...

7. Find your vehicles resonant frequency
(Technical/Theory and Physics)

The resonance frequency of your car isn’t 65Hz. This is a common belief and one that is completely incorrect. In fact, without a diaphragm, or some other vibrating object, there is no resonance. The term ...
