I've found "Pyle 3" Mini Cube" speakers excellent for the K3.  Not
only are they small (about 3 5/8" x 3 5/8" x 4 1/2") their response
is noticeably rolled off below 100 Hz - and, I suspect somewhat below
200 Hz.  These "front facing" speakers are a treat with the K3 and
most other rigs I've had a chance to try them with ... and they even
manage to make the "flat to zero Hz" ESSB fools sound reasonable.
