I was just browsing the Technics website and I noticed a speaker called the SB-AFC410. It claims a frequency response of up to 50khz(-16dB). My biggest question is why? Why would anyone want to have these frequencies played back. I mean we could not hear anything above 20 khz. I know with bass that sound below what you can hear can still be felt but what benefits would such a high frequency range have. I also notice they gave the response with -16dB while the Paradigm titans I am going to buy are around 60hz-18khz with only -2dB. Are the specs for this Technics speaker misleading?
