The old ditton 66 reached 40 kHzMost of the Salk speakers rated upper end says 40Khz.. Isn't the listening capability of the human ears if you are lucky goes up to only 20Khz? what am I missing
What would a 40Khz sound in real life?
It sounds like silence!What would a 40Khz sound in real life?
You can't hear distortion above your hearing range and increasing the frequency range doesn't improve power handling, (You can fry a tweeter with frequencies you can't hear, whieher the tweeter is actually reproducing the "sound" or not,)In that case you want to make sure your speakers can handle those frequencies without distorting or burning up.
This is generally a feature of aluminum and titanium tweeters. Beryllium's breakup modes are much higher up around 40k or so.Also, some metal dome tweeters have a resonance around 27kHz that can cause IMD in the audible range
I have ribbon tweeters that go up above 30Kh but I can't hear above 16 so implement a low pass filter at 17. Not missing any musical content to my ears.
edit: And most of my friends are old too so they're not missing anything either!

It'd probably drive my little dog crazy..
This may be teaching you to such eggs but bear in mind that the filter will likely be affecting phase into the frequency range that you can hear. Unless you have a problem with higher frequency output I'd be tempted to not use the filter myself.
Phase is just fine, I use rePhase to dial in my active XO. Your hypothesis may be correct for random filter implementation without measurements though.
'depending on the filter implementation'
And even then maybe not a huge deal for far field listening after reflections. I correct for phase because I can and I'm just that sort of fella but check out some of the discussions regarding audibility of phase, especially in the upper frequency ranges.
Hey, that'll be interesting. ...I should try some different HF roll-offs - although I probably wouldn't notice.I recently bought a pair of Edifier S3000Pros with a claimed response up to 40 kHz to try out, and I do have it in mind to have a play with different high frequency roll-offs to try to get a feel for what range may actually be useful (to my ears). I'd been mulling over the complications of doing so as a result.
Edit: I've been redecorating my lounge ('listening room') recently and so haven't got round to making any measurements on the Edifiers yet to see what their output actually looks like.
To me it seemed like somewhat unnecessary signal processing with a possible downside.
