Speaker help please!

I have a 5e3 (tweed Fender Deluxe clone) with a Weber Alnico Sig 12, it sounds good, but can I do better? I know speakers are super important, but I don't a ton about them, so please help!
Any suggestions for a low watt speaker, that will sound awesome, full, fat, and break up nicely like a tweed deluxe should? That Weber gets there for me, but I just don't know if there are better options and don't want to drop $200 on a speaker without knowing that it'll improve my amp's sound.
