Many people like the sound of a 1.5 inch exit driver over a two inch.
The 1.5 exits right at the phase plug into the horn instead of having a couple of inches of throat lengh. The 2446 and 2447 are the same driver only the 2446 has a nose/throat that takes the 1.5 exit up to a 2 inch exit. The JBL 2450 and 2451 are the same way. For what it's worth most companies that offer both 2 and 1.5 inch drivers are the same driver bodies with a added throat that goes up to the 2 inch exit.

The smaller exit, otherwise identical drivers have a bit more HF extension due to fewer cancellations in the horn throat before entering the horn itself.
