I think they are okay, but not very movable.  You can't easily put a better 
one in the cabinet.  speakers are very personal choices.  If you already 
have a power supply that meets your needs, why not put the money in to a 
better speaker?  I have seen some with built in noise filters.
I bought a CC radio with the option to drive the amp and speaker with a 
patch cord.  I use it as an output device for my stream, it works great!
Might work as an amp and speaker for a rig or HT as well, haven't tried.
As a radio, it's very disappointing.  Overloads like crazy at the top end of 
the dial.

For the radios, I use an old JVC 501 with a five band equalizer, in to a 
radio Shack two way speaker.  It also has another five band equalizer in the 
circuit.  Very good for AM phone with lots of filtering options.
I have an input for each radio this way.

Remember, "we must have moderation in all things."
