[QUOTE="DidUHearThat?, post: 5018582, member: 594758"] No, it's not an exact frequency, but a slope across that section of the spectrum; 1/3 or 1/2 octave. Depending on how the crossover in the eq is designed it may be 6-12 db per octave slope above and below the center freq. 8 khz is the CENTER of that boost, but not the only frequecy that is boosted. So a sublte boost of only 1-2 at 8 khz should only be noticable at 8 (or between around 7.8 khz - 8.2 khz). A harder boost of 3-4 db at 8 khz, will effect a wider band, like 7 - 9 khz. A severe boost 5-8 db, will effect a wide part of that band (6 - 10 khz), but still centered at 8 khz. It's like the peak of an ice berg or a mountian. At first its only a point, but the higher it gets, the wider it gets. 8 khz is pretty high already. Above most vocal sounds and into the timbre of cymbals and where airy sounds begin. Most stock speaker systems don't go much higher than 10-12 khz. 1 Khz is generally considered the "middle" freq of human hearing. Most of the human voice is 300 - 3,500 hz. Our total hearing range is about 20 - 20,000 hz. [/QUOTE]
