In the recording world, Schoeps and DPA are very popular for distance microphones and close placement too. DPA descended from Brüel & Kjær.

This article is a guide to instruments. They used a distance of 3 meters, and typical close microphone placement distance for the instrument SPL. Many instruments are loud!

That's about how I listen, when listening critically.

85dB averaged, 105dB peaks.

At 3 meters.

I like an "in your face" presentation.

Maybe not a pristine recording but I like Carla Bley...

You need to sit really close to K-horns for the full effect.

There is that time I worked on tuning the sound rig in a strip club. They had ceiling mounted K-horns that were giving the girls headaches. The girls were very appreciative of my EQing the speakers.

Funny, I was just refreshing the specs of the different grills for 4006/4003.

I don't see how "dynamic range" has any meaning for an acoustic instrument that can decay to silence or rest at silence. Silence is minus infinity dB so that's infinite dynamic range.

Silence is minus infinity dB
There is no sound in vacuum, and only minus infinity possible would be there. IIRC, dynamic range is measured relative to the threshold of hearing (aka loosely 'silence'), which is 0 db SPL, which is 20 micro Pascal. And that is reflected in the above pictures with the specs.

I've used DPA microphones a lot and they are amazing. They are some of the most accurate and versatile microphones on the planet.
