[quote author="enthalpystudios"]I just cant for the life of me find where I bought mine (and the price was WAY right, whatever it was), but the model number is P22WP, and is not printed on the mackie versions.

I think they were on sale here:

P22WP is some OEM model propably, though if you get datasheet it may be possible to find close enough Vifa replacement. Mackie propably have them too.

I think you can't find better replacement than this unless you get original somewhere (maybe somebody who bought them from ApexJr could sell you a pair):

This may though be just a little bit too small in dia, maybe the PL22WR driver (though with paper cone) might also do.
