I was fortunate to find a pair of Radio Shack Optimus speakers (5 inch
black cube) at a 2nd hand store for $5. They work great with my K3.
You may be able to find something similar if you shop around a bit.
These are non-amplified speakers and work quite well, no worries about
RF feedback or other problems that sometimes occur with amplified
varieties, and the K3 has more than adequate audio to drive these high
efficiency speakers.
Since the K3 tailors the audio response, there is not really a need for
"communications" speakers - the RX EQ will shape the audio to your
desires, so "full range" speakers will work great with the K3. For those
who do SWLing, the full range speakers may be better for those users
than communications speakers.

I too have used the 2-way radio speakers for more than 30 years and
originally did with my K3. But after going thru the junk stach again
a discovered I had a pair of amplified speakers (not cheap) used with
Radio Dispatch Consoles as SELECT and UN-SELECT audio channels. They
contain ~ 6 watt audio amp and a substancial speaker, power by 12
volts. So I now have plenty of audio and with the speakers spaced
about 6 feet apart there is noticable separation, and the AFX function
is great when desired.
With the extra amplification and volume controls I can set the K3
volume control for hot earphone level, yet turn down the external
speaker levels.
