General audio topics that don't fit into specific categories.

I said rolled off not incapable

There is a difference.

Also and I've been very clear about this - tweeter failures because of excessive high frequency energy - not off topic - goes to the sound of the system when borderline operational or dealing with less than ideal recordings. It's a fact of life for many of us.

"I agree with that concept, but only in the choice of output level - NOT the inherent capability of the signal chain. A system that is incapable of reproducing a 20 khz signal will be inferior across the band to one that doesn't share that limitation."

I think I questioned what "goes to" means in my original post to the OP. Down 3, 6, or even 12 db doesn't mean it doesn't go to 20K. It does/can indicate how it sounds when asked to reproduce those frequencies. My point here is that some roll off probably is a good thing if one doesn't have a full and extended bass response.

If ones using good recordings with good high frequencies flat is a good thing. But not all of us do that.

I checked your gear out - you got fantastic full range audio equipment. I'm sure you have the rooms and the recordings to justify it. Consider yourself lucky. I have two great audio systems too (neither one full range) - one in a bedroom and the other in a smaller bedroom.

I listen to all kinds of pop/rock recordings and venture to guess that less than 10% of them have useful energy beyond 15Khz (maybe much less). I'm betting your music collection is considerably different than mine.

That said I'm just trying to help answer the OPs question. And FWIW I haven't blown a driver since the 80s or very early 90 but I'm sure thousands and thousands of others are being blown every year.
