Phil,
You really need powered speakers on the KX3, or a very sensitive speaker
- like the one used in the K2, housed in an enclosure.
Keep in mind that for the K2 speaker, the K2 enclosure itself provides a
good cavity - the speaker sounds weak until it is mounted on the K2.

Instead I hooked my SP3 speaker into the headphone jack on the KX3. Volume was fine for the actual signal but the monitor sound level was not very loud. Due to the fact that the band was noisy this morning (20 meters, 14.014 MHz to be more precise) I had significant trouble hearing my own CW via monitor. With monitor volume level turned all the way up, 40 I think, it was distorted enough to be causing ill to my sensitive ears.
