      I think the RF engineers have been mischaracterized just a bit. Take for 
instance
Messrs Packard, Hewlett, Vollum, and nameless others. You cannot miss calling 
these likes RF engineers. Think about one of the largest markets ever in 
electronics. 
Oscilloscopes, signal generators, frequency synthesizers, and many more that 
also 
have to work over very broad ranges of frequencies. My very old TEK 661 scope 
goes from DC to 4 GHz. Hardly a microhone and a speaker! My specialty was 
function generators. They go from .00001 Hz to 40 plus Mhz. We called it 
designing 
from DC to Daylight. These kinds of electronics cover the audio world and miles 
on
either side of it. I never saw it as looking down on audio engineers but as 
yeah we 
had to do that too. We had to cover all kinds of inputs and outputs, floating, 
differential,
coaxial, current mode, and others. No specialists, we just had to do it.
     BTW, Howard Vollum (founder of Tektronix) had one of the largest Klipsch 
horn
type speakers you might ever see. It was built into the stairwell+ in his 
multi-story house.
