I use only 1" exit compression drivers, which typically have a 1.5" to 2" voice coil. All things being equal, bigger voice coils are better because they have greater thermal capacity. But all things aren't equal - bigger voice coils have greater mass and that kills top end extension - not something you want in a tweeter.
