GLOSSARY OF AUDIOPHILE TERMS
|1 2 NEXT|
Analogthe actual sound wave.
Baffle bounceReflection off the baffle of the sound wave after the main wave has launched. The larger the baffle, the more bounces.
BandwidthAny spectrum of frequencies used for discussion. Audio bandwidth is 20hz to 20,000Hz. Subwoofer bandwidth might be 15Hz to 45Hz etc.
Bass reachAbility to go down to the low frequency extremes.
Bass tightnessTuneful, accurate bass not bloated or muddy.
Bi-ampingUsing one channel of an amplifier to drive each Ribbon and midbass so that a stereo pair of speakers requires 4 channels of amplification. Means that instead of driving a speaker full-range with a single channel of amplification, through a single set of speaker cables, you actually connect two sets of cables, with each set driven by a separate amplifier, or separate channels of a multi-channel amplifier. This way, low frequencies and high frequencies each receive dedicated amplifiers.
Bi-wiringRunning separate cables from the amplifier to the Ribbon and midbasses.
CablesCarrying higher voltage and power, running from the amplifiers to the speakers. Also power cables
CrossoverDigital, passive, electronic - means of channeling high frequencies into the high frequency driver (Ribbon midrange/tweeter or dome tweeter etc.), and low frequencies to the woofer.
DiffractionAnomalies created when a wave moves out from the diaphragm and encounters a radical change in the baffle - say a 90 degree corner. The sharper the corner, the greater the diffraction effect.
DigitalThe soundwave is broken down into a digital format which bears no physical resemblance to the original analog waveform.
Digital chainWhere the complete signal path is digital and there are no analog steps except when the amplifier converts the digital information into the analog waveform which powers the speakers.
DispersionHorizontal, vertical - radiation pattern - how evenly the soundwave moves off to the sides and up and down.
DynamicsAbility to play loudly and cleanly.
EQEqualizing electronically to deal with room acoustic problems or produce special effects.
ExcursionForward and backward movement of the diaphragm.
EtchedEmphasis of very high frequencies sounding very live but harsh.
HardToo much mid-treble emphasis leading to rapid listening fatigue.
