To me the critical midrange is 400 to 5000khz - I do not want any
serious peaks or dips in the midrange. some peaple measure the
bass relative to the 1000khz mark. There are not that many book
shelf speakers that go real low - in a small room they can sound
bigger. A good designed speaker with a true -3db around the 60hz
area, will sound good with a lot of music. The trick is for the woofer
to roll off cleanly after its limits.
I am not trying to sway you from the Classic Three, it still looks
good around 60hz, and I like the NHT products, I have owned a
few and demoed a few. I am not trying to push you towards the
Boston 260, - all I can say is, that it will easily crossover to a sub
at 60hz. You do not want a speaker that goes real low, to cheap
out on the midrange. The Ascend Sierra is a well respected speaker
and maybe someday, I can hear it. Good luck with your adventure.
