    I use PC speakers for my radio. Nothing fancy but works fine.

    As WD4IGX stated, Yaesu does make some speakers with filters for rejection of high-frequency noise. He also tells about getting the same effect from a DSP ( Digital Signal Processing ) equipped speaker or building your own filter ( analog or digital ). I was very happy with the Yaesu SP-4, which is not exactly an easy number for me to remember. I did use it with a Kenwood TM-D700a mobile that I mounted in remote locations. The high-cut filter ( a switched 47ufd cap according to another site ) reduces fatigue on long mobile calls ( especially as you get further from a repeater and the S/N increases ). You can see what others say about the SP-4 on a different website, e-ham net. I hope this helps- Numbers 6, 24-26.
