Should I bypass the resistor in the crossover?

I'm still playing with my Toshiba 2-way cabinets. I've swapped the Peerless SKO 165 6.5" drivers for Boston Acoustic 7" units.

Apparently my ex wasn't lying - 1/2 inch does make a big difference! I've lengthened the port, lowering the tuning frequency by 12hz. With the replacement drivers the speakers are noticeably louder for the same input. In order to keep the response reasonably flat should I bypass the resistor in the crossover?
