Let's put this 'frequency extremes' thing to bed once and for all -
there is
no shortage of high frequency with just about all the drivers I have
used/considered

The BBC traditionally only required sound flat to 13Khz. Being in my
50s, I consider that quite enough. I don't think it's the extension
that matters but the delicacy and faithfullness of timbre.



I don't worry about the 'figures' Andy - as I've just said to Don, it's the
sound (*only*) that counts. It's not what 'horns' may (or may not) do well,
it's that once you are used to them, going back to ordinary speakers is such
a depressing experience.....
