maybe somebody can answer this:
when i first smoked my sub amp,i used my 100wpc technics receiver to power it,i had a teac 10bd/ch eq in the tape loop.the only x-over i had was the 1050(80hz).when it would hit strong bass notes,i would see levels as far as 4khz on the spectrum.why?
possibly noise i've thought,but who knows?up at 4khz there would just be a flicker,but the lower on the spectrum the higher the level.if i would hit say:+6 @ 62hz then i could still see 0db @ 250hz.that doesn't seem like a very steep x-over,but it works very well,because that is still the only x-over i use for the sub(different amp now)
somebody enlighten me.
