Okay, so I've done some more shopping around (now that I am on my center speaker kick). All the center speakers I have demoed, list higher top-end frequency response ranges (some by quite a bit-30,000 Hz, i.e.-http://www.bestbuy.com/site/Definitive+Technology+-+Mythos+Three+Dual+4-1/2%22+2-Way+Center-Channel+Speaker/6639364.p?id=1151658129688&skuId=6639364)

Now, I understand that the human ear can readily perceive from 20Hz - 20,000 Hz and that the perception of the upper range decreases as we age, but I still feel like I'm somehow missing out by getting speakers that "don't go to eleven" by capping out at 20,000 Hz. Thoughts?
