It will all be dependant on the material and its natural resonance.No but thats absolutly no reason why 25khz should destroy them faster than15khz.

I don't think we have a measurement for the LSR306P MkII yet. The Hiss List shows:Please, has anyone measured the reported hiss ?
Tweeters have far less thermal mass in the voice coil (or whatever analogue) than a woofer or midrange driver, and woofers/midrange drivers are designed to take a lot of energy (bass needs much more energy input to reach the same SPL, plus tweeters have to be lighter and quicker reacting than a woofer or midrange driver). So while the woofer or midrange may be unhappy in terms of sound quality, you're not likely to destroy them with a high level 5KHz signal.No. If 5khz not destroy a bass in a second why should 25khz destroy a tweeter in a second? Hope you can explain?
It wouldn't. 15KHz and 25KHz at high level will wreck a tweeter the same way. The voice coil wires aren't heavy enough to deal with sustained continuous high power. The point is that you can't hear 25KHz. There's little if any reason to allow a lot of energy up there.No but thats absolutly no reason why 25khz should destroy them faster than15khz.
Thank you.I don't think we have a measurement for the LSR306P MkII yet. The Hiss List shows:
JBL LSR305P MkII - 28.5 dBA
JBL LSR308P MkII - 30.0 dBA
Because these designs are so similar it would be reasonable to assume until measurements are taken that this model will fall somewhere in that range. So, not great, but not the worst.
It's white noise or something close to it.Thank you.
And the frequency the hiss is enjoying us with ?
Any idea ?

Oh come on.
Edit says: The only reason tweeters can be destroyed by ultrasonic is that you can hear nothing and give out of this reason to much power.
Not yet, but that's a request I brought up in the Hiss List thread because, like our earlier discussion, I believe the timbre of the hiss can potentially influence its perception:And the frequency the hiss is enjoying us with ?

I wish we had spectral measurements of the hiss for each speaker beyond a simple dBA measurement because I think it's possible that different people may find different kinds of hiss to be more or less tolerable. Most of the hiss spectra will be similar to a colored noise profile but I think most people would prefer pink noise over white noise, for example.
Realy expensive way to light a cigarette.Or may be you simply blew the candle too much !!!

Good thing.Not yet, but that's a request I brought up in the Hiss List thread because, like our earlier discussion, I believe the timbre of the hiss can potentially influence its perception:
Oh, come on...10000000 Hz harmonics are there !!!Realy expensive way to light a cigarette.
Oh, come on...10000000 Hz harmonics are there !!!
We could even make a patent granting every single buyer a Niagara-Falls-like-ultra-relaxing hissing !!!!Not yet, but that's a request I brought up in the Hiss List thread because, like our earlier discussion, I believe the timbre of the hiss can potentially influence its perception:
Now you are confusing acoustic levels with an arbitrary relative level on a random plot (that you provided)Good thing.
Then we could possibly compare that not at all important hissing at -28/-30 dB with those to-die-for-harmonics at -83 dB.
Please, has anyone measured the reported hiss ?
I mean, frequency and level heard after playing music at say 55-65 dB and stopping it to get the measurement ?
Engineers and architects call them scales.<g>It is a $10,000 ruler....

BumpSeems like anyone who actually owns these is quite satisfied with what they received for the money spent. I am one of those. There is audible distortion, but not overly objectionable at low listening levels. There is audible hiss, but not to distraction, and I use them as desktop speakers for my PC workstation. Whether or not you’ll be happy with these probably depends a lot on how fussy you are.
I’d like to apply the EQ correction. Sorry I’m such a rube, but is it as simple as loading the file posted by @Maiky76 into JRiver DSP? Is there a post somewhere that explains the process in detail?
