With my new Mac Mini (2009) purchase, I decided to get some decent speakers to match. After checking CNET and Consumer Research, decided on Harman Kardon SoundSticks since they're reviewed to have pretty good sound quality. After receiving the SoundSticks and hooking them up to the Mini, they sounded pretty good from iTunes Radio. But I thought the high end good be better. As an audiophile type with a good 2-channel system in the living room, I can hear if something's missing. So I downloaded a free audio tone tester, AudioTest 1.12 to check out the SoundSticks claimed specs of 44 - 20,000hz. Well, I can barely hear the 10,000hz test tone, but nothing above that. I hooked up my older round little Apple speakers and also a pair of older Creative speakers, and the same situation. Wondering if I'm expecting too much out of $105 computer speakers? Do they really all go to 20khz as claimed? But what gets me is why do they advertise computer speakers as going up to 20khz if they can't? Anybody else care about this stuff, or is low end Dinosaur chomping sounds in movies and computer games the only thing people are looking for in computer speakers??
