I'll be very blunt.
I am not sure why some preachers do it. Why do some preachers feel compelled to yell and be charismatic and not just rely on their words? I hope I am not insulting any preachers here because I am not intending to do so but I have seen yellers look up to other preachers who are normal speakers. The normal speakers are usually very educated (M.divs, authors, or thds).
I don't refer to the loud emphasis like RC Sproul or Piper who sometimes emphasize certain statements. I am referring to people who have a fine working audio setup and yet belt out everything to the ends of their vocal capacity. Perhaps a paragraph or two.
I can't imagine J.Edwards or J.Owen doing this.

How do you guys feel about this? Do you do it? Why?

Whenever I have preached, I put emphasis on the applicatory notes and some key points but not to the extreme where my voice will break. Should I?

I guess I am writing this (thinking in retrospect), because I think I feel a little bit of nervouse pressure because I feel that I HAVE TO preach loud in order for it to be proper or right. Spurgeon says that if you don't have the manliness to belt it out you do not qualify, but I think he referred to the era of time before audio systems.
