Hello all,
I'll be posting this on a few other Audio/DIY forums because I almost always come across the same argument that Frequency Response isn't the only factor when it comes to Speakers/Headphones but I don't have a good knowledge on what else matters.
For example, let's place three speakers in a Anechoic chamber (Removing room acoustics for sake of discussion) as well as assume that the three speakers chosen will all have a FR of 40hz to 20KHz +/-1.5 db. With these assumptions if I the listener heard all three speakers (Maybe one being the top of the line Genelec Studio monitor, another being lower end KRK speakers monitors and the last being the Orion (a well received DIY speakers) I think most would agree that each would sound different. Where I get confused is that 1.5db is very difficult for humans to distinguish between yet (and I may have this all wrong) the three systems would sound quite different even though the listner is hearing the same frequencies from each speaker... So from my perspective 8hz should sound the same no matter the source. This is where I'm looking for some education. I know there are numerous graphs posted alongside FR graphs and these are what I assume cause a sound difference even though the FR is for the most part identical.
I tried googling and reading through forums to find the answer yet I'm not finding out nearly as much as I'd hope. How does a speaker produce a flat FR yet contain distortion or other anomalies while maintaining a flat FR?
If any of you know some good material to read and can link it for further explanation that's just as good as a lengthy post.
Thanks for your time. I just want to be able to created a great listening environment and am interested in how to accomplish this without using FR as my only guideline.
Joel.
