The Hallicrafters bass reflex speaker cabinet for the SX-28 had fabulous
flat response ... down to the deep bass if you drove it with that. It
also employed a fairly large speaker and was big ... very big, and took
a few watts [8 peak, I think] to drive it.
In the late 50's, in college and on a limited budget, it was common for
students to use 5 or 6" speakers in tight cubic boxes made of 3/4"
plywood and stuffed with some wall insulation for the then-new stereo
records. They sounded pretty good and doubled as supports for the
ubiquitous cinder-block shelving. My roomie and I painted ours black.
Why wouldn't one of those work?

While I agree that the speakers should not color the transceiver,
excessive low frequency response on receive is as wasteful as excessive
low frequency response on transmit. In that regard, I'm very happy
with a pair of Pyle PCB3 (3" Mini Cube Bookshelf Speakers) - one left
and one right. They are specified for 90 Hz - 18 KHz and I *still*
use the maximum RX EQ cut on the 50 and 100 Hz bands.
Speaker response above 5 - 6 KHz is moot since the K3/K3S includes a
4.5 KHz "brick wall" lowpass filter in the headphone/speaker channel.
