Most likely buying a pair of KLF-20s tomorrow (if no one manages to get to the sale before me!) and I'm curious, I just heard my friends KLF-30s and they sounded harsh on the high ends, without turning the volume up "too" loud at all. He just bought them as well and hasn't fine tuned his settings yet, so I guess this is a post from the both of us since I obviously don't want the same issue with my possible 20s. Could this be solved by simply changing the amplifier settings? Or does this require some modification / seem typical of the KLF series? I've heard such good reviews and have heard (other) KLF-20s myself before and been very impressed and not noticed this before, so the harshness of these 30s is confusing to me.
Also, would you guys recommend a sub with the KLF-20s? I won't have the money for any nice sub upgrade anytime soon but it's definitely something I'm thinking about for the future, assuming i do get the 20s tomorrow.
As always, thanks for the help! Learning new things everyday from this forum.
