Of course. And in speech reinforcement systems, we carry response up to 
at least 10 kHz. BUT my advice is for weak signal communications 
circuits for DXing and contesting. Band congestion is extreme during 
both of these conditions, so the use of ESSB is out of the question for 
these times.

That's a fine microphone. I own several, also RE20s, which I use for 
recording music. They are my first choice for trombone, and for tenor 
and baritone saxophones. It is massive overkill for ham radio, and it's 
a relatively flat mic, so it lacks the built-in boost around 3 kHz that 
good communications mics provide.
