Excellent article Mr. Moulton. The best guide to EQ.

forgive me if i`m being ignorant here but whay have you listed 260hz as middle c?

i`ve allways thought it was 440hz..

440Hz is actually A not C

yeah thanks, i`ve seen the error in my ways. nice article!

thanks so much for the article I got alot out of it and I'll continue to look for more of your Articles thanks again

uuuuu!! nice I really like your articles - the unknown settles like a missing puzzle to my knowledge. I will buy your book Total recording for sure.
Thank you for sharing

wowee, one of the best articles on eq/frequencies etc. that I've ever read. And I've been reading a bunch lately.
