It does what it is supposed to do. It's a straight fit replacement for a (Fostex) Yorkville YX15 diaphragm

This diaphragm matched the horn in my GK bass cabinet. Works great, install is a snap, and it sounds good. The price is gret and the guys at SS are very helpful in making sure you get the right stuff.
