Hong Guan, look for Mr Thomas

Thanks

Just wonder if our human ears can pick up that range of freq...the sensitivity of human is from 20Hz to 20KHz depending on individual.

hi bro, who install the sound system for u inside the car,cheers????

[Blitzza]

All top grade system. In which car? Any photo?

Sometimes, I think its more of a show of technology rather than practicality. Esp since Focal invests heavily in R&D, they need to show something.

 

Utopia itself sounds wonderful.. but I kinda doubt it has anything to do with frequencies above 30khz coz like you pointed out.. we can't hear.

I rem I read somewhere about this high frequency stuff. Its all abt aliasing which half the frequency. Most amp filter off this frequency as it treat them as noise but expert says this is what contribute to the depth of sound, thus this set of speaker have to work hand in hand with a good set of amp that have the cpapbility to not filter everything off.

Therefore, reliance on mere superficial spec published by the manufacturer will only leaves false impression on how the speakers can allegedly perform. Of course, we believe and trust that reputable manufacturers provide genuine facts rather than sale gimmicks but in this modern society, listed spec meant more than anything, more so than our own pair of ears. WE trust our eyes (of what we see) more than anything else, therefore, who has the last laugh?

 

What I opine is to realistically accept the fact, a scientifically-proven fact, that our ears can only pick up until 20KHz. Now, even at 20KHz, there are already some speakers that are struggling to sustain at that range at a given energy (power) and duration without going into distortion. Of course, I will have to say Utopia line has reportedly proven to be able to do so though my humble experience in music can't really vouch for it.

 

I also think that when we invest in any particular branding, we have trust and confidence in their quality and the characteristic of the brand's ranges of speakers. So long as you genuinely prefer the music reproduction and the true characteristic of the speakers over BRANDS of speakers as your guiding principle, you earn my respect. But if people are obsessed in pursuing BRANDS because it will speak well of them in their cars, I think, there is a big misconception in ICE after all.

 

I really do not know if space has got to do with the supposedly "higher freq". If higher freq is associated with depth and space, how do you then fuse the theory you mentioned into let say, for our ears to distinguish a REAL big empty room from one that is not, since our ears can only hit the most 20KHz?

Hi, my humble setup is in a Toyota Wish. I will PM you the installer if you are interested.

Sad to say, I have not gotten any chance to photo them yet...

You're correct

 

Sound comes in 2 stages and simply put: base frequency and harmonics.

 

Usually the base sound are those we hear very distinctly. However, the harmonics will then come into play and leaves the trailing sound.

 

The trailing sound gives the roundness and the depth. However the tweeters rate of decay is impt coz if the rate is not fast at high frequency.. we get a prolonged existance of the high frequency which might cause headaches in some folks.

 

Tweeters will ability to go higher than 20khz will help deliver the 2nd stage to give a more 'complete' & 'realistic' sound image.
