which midbass would be better?

[kan3]

can't decide between these two drivers

eminence alpha 10 vs eminence BP102

these are going in car doors so basically an Ib install
range is gonna be 60hz-150ish with an 18db HP and 100wrms on tap for each driver

the alpha is $42 a driver vs the bp102 $62 a driver

alpha: QTS .59 / FS 50hz / efficientcy is 92-94db over my range/ xmax - 3.2mm / sd - 355cm^2

bp102: QTS .46 / FS 40hz / efficientcy is 89-92db over my range/ xmax- 6.2mm / sd - 334cm^2


so would the bp102 work better with its lower qts or should i stick with the alpha
