Why Does It Have To Be 50hz

[javy101]

u know that to set your gains you are suppose to use a 50hz sine wave for the subs. i wasjust wondering why it was 50hz you think that if i used a 55hz sine wave it would be ok

well an amp can somewhat be like a house receptical, i seen a vid somewere of someone usein a jbl gt6000 powering a saws all from the speaker outputs ona 60htz tone, why im sayin this is cause an amp has an alternateing current and its best is around 50-60htz cause thats were most music lies around and gives a good freq range from low to high if im not mistaken its prolly what is best to use for what the power supplys put out at, hope this answers ur question

so a 55hz test tone should be good

ya, ive read anywere from 50-60htz, i dont really see any diff between the 2 tho but i can tell taht a higher freq pulls more current than a low freq does so thats why they say use a 50htz tone, but settin an amp with freq is wierd tho cause u gotta add into factor ur bassboost and ur sub sonic filter also, maby this will be more informative tho http://www.stevemeadedesigns.com/board/ind...?showtopic=4382 anyways happy posting

i disagree

just as long as its a constant tone that lasts long enough to get an accurate voltage, A/C meters do read the AC current most accuratly in that range 50-60hz

On a sub amp you want to use frequencies between 50 to 60hz because that is where the crossover peak is. Those frequencies are least affected by the crossover or infrasonic filters.

download audacity and you can make any sine wave you want

Negative ghost rider. More power is needed to generate a full power low frequency waveform than one of a higher frequency. Also, most loudspeaker's have the lowest resistance at borderline sub-bass frequencies. Less resistance=more power from the amplifier. 50-60hz however is a mean average of most bass testing. That, 100hz and 1k are pretty much standardised test frequencies.

i disagree

I agree, it's spot on. Why d'you think the make tweeters small.

Theoretically you could put 20kHz out of a sub, but the ability to control such a thing would be and incredible feat...

50Hz just gives the spot on calibration for the gain setting guide. If it were 55 it's be different but only marginally i believe.
