I'm building a 4x12 cab and i'm trying to decide what speakers would be best for the job.

I've been looking on the eminence website at their sound clips and i seem to like the Wizard very much and the Cannabis Rex.

I've not heard a direct comparison of the Celestions so i don't know how well they compare so i'd like some suggestions from people who have maybe tried out any of the celestions and eminence speakers.

I play mainly progressive stuff, nice cleans are necessary but i like to add in a lot of drive, not metal style gain but certainly a modern rock style drive.

Which speaker would you suggest loading the cab with? or would a combination work?

Check out warehouseguitarspeakers.com . There are some nice ones there, comparable to Celestions imo and wayy cheaper.
