Icom Avair Speaker 650
This TS-650 style external speaker build-in indepence Amplifier circuit, has a switchable noise filter.
Suitable for your CB radio or Ham radio communications. In my testing, I do not hear a huge discernible difference when I active the filter.
This inexpensive speaker should work great for your basic listening purposes.
