I've been using the Pyle PCB3 series "cube" speakers since well
before the SP3 was introduced. The Pyle speakers are spec'd at
90 - 20 KHz (about the same as the SP3) and are easy to drive
as well.
I notice no difference in response between the speakers and my
headphones (typically Yamaha CM500 but occasionally smaller,
ear bud or "professional" Sony headphones) *HOWEVER* I have the
K3 RX EQ set to roll off (-16 dB) the 50 and 100 Hz bands with
a -6 dB roll off in the 200 Hz band for SSB/AM and with -16 dB
at 50 Hz and -3 dB at 200 Hz for CW.
There is no issue for me with the roll off if/when I listen to
AM or shortwave broadcast but I can certainly "flatten out" the
response by changing the RX EQ to flat or even add a bit of low
end boost if band conditions are quiet/no QRM.

Bill,
Personally, I like the SP-3 speaker. I have two of them and,
compared with my Koss headphones, they both sound like
the headphones. Great for the K3 on SSB or CW. Not Hi-Fi
for music but entirely adequate. PLUS, they look good
in the K-Line.

In the real world, does the SP-3 exhibit well rounded frequency
response? Or, is the response more directed for "communications use"?
How is it for listening to AM broadcast? How does it do with the famous
K3 hiss? How does it do with a less capable receiver (one without an EQ)?
I am considering some station simplification, hence the SP-3. Currently,
I am using the Behringer MS40 pair. Super sound, but quite large and do
have an internal amp (I have experienced no RF problems).
