[Elecraft] Speakers - Optimal Frequency Range?

[Edward R Cole]

As many of you know I suffer extreme hearing loss (especially high 
freqs), so Don's comment really hit home for me.  Several years ago I 
debated buying a home theater system with prof. speakers as I 
wondered if I could discern the improvement.  I found that having 
very linear response from 50-Hz to 20KHz improved understanding of 
voice on the TV as well as enjoyable music.

Later, I found choosing the flat response program in my hearing aids 
also provided the crispest voices and better understanding.

Long ago I bought a pair of Sony stereo headsets for listening to 
weak signals on ham radio.  Appears that also was a good move.

So even if the audio output is restricted to 300-4000 Hz the speaker 
reproduces that faithfully.

My new blue-tooth capable hearing aids have much wider freq response 
as I am hearing a wider range from low to high freq.  The plus is my 
iphone connects directly to my hearing aids for best hearing in 
public (and that half is private).  I have yet to try using bluetooth 
with my K3.  Let you know how that sounds, later.

PS: my KX3 audio will be connected to the truck speakers via sync; 
more on that, later.

Bret,

In my opinion, a speaker should not "color" the audio response of the
receiver.

While it is true that there is not normally much response above 4000Hz
from a ham transceiver, the speaker should not be the limiting factor.

IMHO, the best characteristic of a speaker is the flatness of its
response curve rather than its frequency range.  A speaker with a flat
response will allow you to hear the transceiver "as it should be"
without distortion. So my vote is for "High-Fidelity" speakers.
