I also use the Clearspeech box that came with their inferior speaker. I 
replaced the speaker with a Motorola MICOR (unpowered) speaker from the 
old mobile radio of the same name. Great performance. Can't possibly 
overdrive a Micor speaker. They can be found at hamfests all over for 
less than $10.00.
