I actually swapped out the JBL drivers for the Seleniums last night. They sounded way less harsh but yea a little bright...the higher extension is noticable and sounds kinda nice. They don't have as much weight or heft sound wise as the JBLs...I can tell the horn is having a negative effect though..the smaller horn I used to use with the seleniums sounded much smoother.
I think I'm gonna order the new horns and give the JBLs another try...if I don't like them I'll sell all six drivers (JBLs and Seleniums) and get the B&Cs.
