thats what I meant.....just opinions, thats all, not facts, and maybe not even close

if your opinion is based on your own experiences, it will be as good as any.... until proven right or wrong

as I said to you, we are all entitled to have our own opinion about it, just not claim it is a fact

It certainly won't do dynamics like some systems will, but one pays a price for that too...

As far as dynamic compression goes, it is valid to say that that is a symptom of using a voltage source amplifier. Use a current source amp and dynamic compression goes away.

Now we are back to "a loudspeaker cannot be considered independently of the amplifier (and the cable that connects them together)"

What speaker system are you using?

I have 3 different speaker systems, currently running a 3way Hybrid Dynamic driver/ribbon speaker of my own design.

Its a current hog ....

PS: By my previous comment on size, i meant Image size ...

There are other things that limit "dynamics" far more than the loudspeaker . . . clipping and compression start all the way back at the microphone, and is regularly and deliberately added at multiple places in the chain after that. Most of what passes as "dynamics" in loudspeaker demonstrations is simply playing them louder . . . which some speakers certainly can accomplish better than others. But it is often a "louder than life" loudness, and that makes the apparent "dynamics" an artifact of our hearing, not of an actual increase in "dynamic range".

It is a lot easier to characterize a "driver" when it has a constant resistive (say 10k) input impedance .

We are focusing on speaker not system dynamics and I'm not sure what you mean by "passes" for dynamics !

It either has dynamics or it doesnt ..

All speakers "have dynamics" . . . they wouldn't be speakers otherwise. And any decent speaker will have linear dynamics up to clipping/compression, so to get equivalent "dynamic range" to a speaker that can play louder all you have to do is turn it down.

All speakers are used as part of a system . . . and in the systems that we have there are limits to dynamic peaks. If system levels are set so that 0dBfs does not drive the speaker past its limits then it will deliver the same "dynamics" as a speaker that can play louder . . . just at an overall lower level.

To say all speakers have dynamics is not totally true , yes all speakers will show dynamic changes , the rate of change and its size is whats different, For eg play a single fullrange driver at 90db and the same to a large 3or 4 way system , there is a huge difference in presentation , dynamics and weight...

There are recordings with 30db+ of dynamic range, dynamic compression will show its head from the first note , dynamic compression and noise(hash) when present will promote those to make the same comments you made previously about dynamic range and loudness ...


Dynamic range is not about loudness , systems that lack it , are the one which tend to sound loud , those that don't , the music just seems to grow and swell in volume , with an ease very similar to live music ...

The speakers under discussion throw a realistic (big if necessary) 3D soundstage and the speakers are good at dissappearing.

I imagine they sound good in this respect.

How does this tweeter perform from 100Hz to 4kHz compared to Peerless 830870?

Regards,

Andrew
