i know this subject is beaten to death but this time i actually have some specifics

im either buying a BL 15 or 18

this is going into an 09 scion xb (hatchback/crossover)

upfiring

for the 18 this is probably the box i would build

14 sq inches port per foot

about 6.22 volume or 6.5 if i invert the sub

or, i could do a 15 and put it into the ideal box, as there is definitely room for one

the 18 will most likely be louder. and 6.22ft^2 (net,or gross)?

a 15 can be louder then an 18, more cone area does not allways win.

box and such.. i know

yea, i know a 15 CAN be louder, but given the specs of my potential box what do you think WOULD be louder?

hell, if i knew i could make a single 8 louder than an 18 for the same price i would, im not one of those guys that thinks a big sub is gonna make my d!ck look bigger

here's a bigger pic i hope

assuming this calculator shows net, then yea, its net volume

any other input?
