New JBL project

While I have my L7s in the main system, my 4 cu. ft. cabinets with LE14H-1s under 2344 and 2226s are due for an update.The LF crossover is from the 4430s without the final resistors and a Zobel to smooth the impedance at crossover. The HF system is built exactly to the 4430 schematic.Is there a better 14" woofer to put in there? Currently the combo plays very smooth and is at -3dB at 34Hz. I have 2214s but don't like how they model in that cabinet...and they're 12s which would require a new motor board.Distilled question - which JBL woofer would be the most appropriate to update my setup?
