does the size of the magnet have anything to do with the sound it puts out?

It does, but then it doesn't. Magnets provide flux for the coil to move through, the two combined being BL. You want just enough BL for a given design and that's it. In fact too much can actually hurt you. But just because one speaker has a larger magnet than another doesn't make it better.

Also sometimes has to do with the material that the magnets are made of...Cheaper material may require more of it..

Example Neodium magnets do not have to be so big cuz its a very good magnetic material...

Thats my dime....

Come on now, it isn't how big it is but it is how you use it.
