This thread has gotten long so I risk getting chided for replying so late.

I only used the internal K3 spkr for a couple days when the radio was 
new.  I switched to an old "venerable" National Radio 8-inch speaker 
from the 1950's housed in a metal enclosure.  I was made for 
communication receivers and has sounded great with most of my ham 
radios (now dedicated to the K3).  No amplifier in it.

I bought a pair of the COMspkr's for my wife's computer as result of 
my RFI getting into it when I ran HF (especially 20m).  I am looking 
for a better solution for my KX3 which is using some old HK computer 
speakers.  I have never been impressed with their sound (on 
computers, with the SDR-IQ, and now with the KX3).  The HK always sound murky.

I am thinking to borrow the wife's COMspkr for a test.  As I recall 
they ran about $45+shipping.

I have had no issues with the K3 audio but the KX3 needs something better.

For communications I do not need super-low THD and 20-Hz to 100-THz 
freq response.  For my hearing 300-1500 Hz is good.  On my home 
theater system the low harmonic distortion and wide freq range is 
nice (even with poor hearing it turns out).  I see this a little bit 
apples and oranges.
