delhite2 Posted June 26, 2008 Share Posted June 26, 2008 i've just decoded that klipsch speakers (most of them) have frequency response of xxHz-23Khz whereas some other brands (as JBL es-100) support higher-wider frequencies example xxHz-40Khz. is it that i'm losing on something (some critical or uncritical parts of audio), is 23khz and above all that relevant?

Mr. RF62 Posted June 26, 2008 Share Posted June 26, 2008 In my opinion, I think it is irrelevant as I don't care what my cat or dog thinks about my sound. I can hear up to around 20kHz, and as I get older I will hear even less. Supposedly people around loud music or older folks will have a response of around 15kHz. I like that they only go to 23kHz as I don't want to think of the power from my amplifier going to these sounds I cannot hear. [] Quote Link to comment Share on other sites More sharing options...
Klipschguy Posted June 26, 2008 Share Posted June 26, 2008 I can only hear up to 28.5KHz @ 0dB down and I find there is very little musical information up there on most recordings. Quote Link to comment Share on other sites More sharing options...

Don Richard Posted June 26, 2008 Share Posted June 26, 2008 is 23khz and above all that relevant? No Quote Link to comment Share on other sites More sharing options...

boom3 Posted June 27, 2008 Share Posted June 27, 2008 Forget the specifications...it's a numbers game and even an A/B comparison might produce misleading results. At frequencies above 20 KHz, the absorbtion of the air in the room, which includes the factor of humidity, comes into play. There is an issue about "supersonic" response that is not widely known or discussed. One is that these frequencies, although they cannot be perceived in the usual way by the ear/brain system, can have an affect on listeners. the Japanese have done some interesting research in this area. This research and subjective experience-mine and others-leads me to belive that tweeters capable of response beyond the usual limits may irritate if they produce significant distortion at frequencies above the normal range of adult hearing.

John Warren Posted June 27, 2008 Share Posted June 27, 2008 It may say something about the drivers transient behavior since frequency response and transient response are orthogonal views of the same thing. Quote Link to comment Share on other sites More sharing options...

John Warren Posted June 27, 2008 Share Posted June 27, 2008 How about asking the question like this(?) Given two tweeters, one with FR 4-20kHz and one with 4-23kHz, which one would you expect to have a better waterfall plot? OR asked another way(?) why make a vapor-deposited Be diaphragm that has an upper limit of 40kHz? Quote Link to comment Share on other sites More sharing options...
DrWho Posted June 27, 2008 Share Posted June 27, 2008 Given two tweeters, one with FR 4-20kHz and one with 4-23kHz, which one would you expect to have a better waterfall plot? There is no direct correlation between frequency response and the waterfall plot... For example, what happens to the waterfall plot if you lowpass the 4-23kHz tweeter to be 4-20kHz?

IB Slammin Posted June 27, 2008 Share Posted June 27, 2008 I can only hear up to 28.5KHz @ 0dB down and I find there is very little musical information up there on most recordings. OK I'm impressed Me Too! Klipschguy, How old are you? With all due respect, and forgive me for asking this, ........28.5KHZ? Are you in the Guinness Book?

Klipschguy, How old are you? With all due respect, and forgive me for asking this, ........28.5KHZ? Are you in the Guinness Book? Woof tc This is a little embarassing. I can hear those high frequency sound bug repellent devices. They say they are inaudible but they drive me crazy. I can hear the damm things. These do not work as bug repellents but I can tell when one is plugged in. Quote Link to comment Share on other sites More sharing options...

For example, what happens to the waterfall plot if you lowpass the 4-23kHz tweeter to be 4-20kHz? I generate time-gates (4ms) MLS Impulse Response between 4kHz and 23kHz. NO filters, A stand-alone tweeter is a minimum phase system so a straightfwd functional relationship betweem frequnecy response, phase and transient response exists. No computational artifacts associated with transformation from one domain to other (frequency to time). Filters cause EXCESS phase and complicate this. From Impulse I generate frequency, phase and waterfall. It's what CLIO, MLSSA, MATLAB and other measurement systems were created to do(?) I have CLIO here, I do it all the time.
