personal preference, drop em both down to 80 to see if that livens up midbass to the speakers that actually should be getting midbass instead of the sub. theres alot of screwing around with hpf/lpf, but also play around with your amp to see what sounds the best in your install
With as loud as your sub is ported tuned at 40, I doubt you'll find your comps will blend any better, no matter how low your crossover is. You'll just compromise power handling most likely, you can always try though
