So I currently have a Vox AC15CC1. I upgraded the speaker to an 8ohm Celestion Blue. The 8ohm was $250 and the 16ohm was $310. I recently picked up a Vox AC30CC1 and I want to put a Red Fang in this one. I'm assuming the 30W 8ohm will be fine? Is there a big difference between 8 and 16? I don't plan on running any external cabinets off these.

You would want to match the impedance of the speaker to the requirements of the output transformer. That is, if the amp is supposed ot have 8 ohm speakers, then you want to use 8 ohm speakers....16 ohms OT? 16 ohm load on the speakers end of things.
Ex: I believe the original AC30's used 2 8 ohm speakers in series for a proper impedance load of 16 ohms.
Check your amps and use the proper speaker load would be my suggestion. Don't buy speakers according to prices. IF the amp wants the 16 ohm speaker, it should have it.

Speakers are built with different impedance ratings in order to accommodate a greater variety of amps. There is no tonal difference between two identical speakers with differing impedance ratings. Go for it, but don't forget to set the switch to 8 ohms on the amp!

Thanks guys. Luckily I have the option of running 8 or 16 on the amp.

You might still look at the 16ohm speakers. The output transformer might have the taps for 16ohm and 8ohm but the effect of runnig the 8ohm tap is cutting your output transformer's full potential down to 2/3's ...research. Its up to you and how your amp runs and speaker selection.
