Alnico/ceramic mix

Has anyone tried a ceramic-alnico mix in a 210-65? Just curious. I've got a 30 watt ceramic 8 ohm I think I'll throw in next to the Eminence alnico and see what happens.

Well I tried the mix. Couldn't hardly hear the ceramic, the alnico over powered it, so bad A/B comparison. I need to try a more efficient speaker, 50-75 watts.
