I have seen several enthusiastic recommendations for the Peavey Impulse II mini monitor which is
fairly small and costs about $100. Does anyone have any experience with it?

Icom and Yaesu both make multi-hundred dollar external speakers that have gotten mixed reviews.

I would recommend one of the Motorola mobile external speakers from the
90's such as a Spectra or Syntor speaker.

I ended up getting a "CLRspkr" speaker with built-in DSP noise reduction. It costs about $215, and
it is sold by West Mountain Radio. Here is a link: http://www.westmountainradio.com/CLRspkr.htm

The DSP in the speaker is significantly better than the DSP in the Yaesu FT-897. I would rate it as
the best accessory I've added to my ham rig.
