Interesting you bring this up as the KL7RA (sk) super contest station
had acoustic tile on the ceiling in the room with six contest
stations. I noticed immediately how nice voice sounded without echos
off hard surfaces. Floor was carpeted.
When I build my new ham 18x26 foot shack I am thinking of installing
some acoustic tile over the operating position (probably not the
entire ceiling). Floor will either be sealed concrete or maybe tile
(embedded radiant heat in the concrete). But perhaps a area rug
would dampen echos?
This is how radio station booths are designed. Person on the mic
sounds like next to you in your living room vs in a barn.
re: speaker linearity and THD also important as freq range. I'm
keeping my eight-inch National speaker in the big metal box. K3
sounds very nice with it. For very weak signals I will be trying out
bluetooth direct to my hearing aids. I spent more for the hearing
aids than my K3 plus accessories.

Of course the room in which the speaker is used has a huge effect too.
I dread to think we'd require anechoic chambers for Hamshacks!
