I used the SP-20 on my K3 for a while, mainly on SSB. I didn't like it. I could never get enough volume out of the speaker without distortion from the K3 to suit me. Incidentally, I also used it on a 746 Pro and never experienced this problem.
I know everyone is going to say get an unpowered speaker, but I purchased the West Mountain Radio COMspkr for $40 and they work very well and sound really good to me (use your 8 band RX EQ to tailor the audio) and I've never experienced RFI problems, even at Kilowatt Plus power levels. The volume level issue that bugged me with the SP-20 is also a non-issue, of course. Powered speakers may not be for everyone, but 40 bucks isn't a lot to spend after you've plopped down over $3K for a rig, especially you don't want to hassle with finding the speaker that gives you the volume level that you're looking for.
