Normal Shelf Wide Bandwidth

(slope =about 4 to 5 dB/oct)

Special Shelf Medium Bandwidth

(slope = about 8 to 10 dB/oct)

"Pultec Shelf" Narrow Bandwidth

Bell Cut Narrow Bandwidth

(just for reference)

22 Hz Shelf Wide Bandwidth

22 Hz Shelf Narrow Bandwidth

33 Hz Shelf Wide Bandwidth

33 Hz Shelf Medium Bandwidth

22Hz and 33Hz are different shelves when the Bandwidth is Narrow

The top graph is for the other 20 Low shelves

LOW SHELF CURVES

Just like most EQs, a 100Hz low shelf

doesn't reach "max" until about 10 Hz.
