For general communications use I am very fond indeed of the speakers 
Motorola made for their various mobile rigs over the years, They are 
very cheap, efficient and sound great for good quality communications 
audio. These are not Hifi speakers but for speech / CW they do a superb job.

Mostly they seem to be a pretty close match in size and colour for the 
K3 too.

Some of them are 2 Ohm though, The ones I use with My K3 at the moment 
are 2 Ohm ones, Since I do not know for sure if the AF amp in the K3 is 
happy driving an impedance this low I stuck a 2Ohm 2W resistor in series 
with each speaker and still have more than enough audio in my shack.

I have seen these available in 4Ohm and amplified variants too. Pretty 
much every radio in the shack is connected to a Moto speaker and I still 
buy them at rallies, collecting stuff I might need someday must be habit

Anyone know if the can K3 drive a 2Ohm speaker without bad stuff 
happening ?
