the factory recomends 1 cubic foot per sub but when i calculate my internal volume for two drivers it gives me 5.452 cubic feet. and i need this to determine vent length. so what the hell?

k well on my specs for my subs that the manufacturerer provided it recomends 1 cubic foot per sub. so thats 2 cubic feet not incluning the volume taken up by vents and sub woofer displacement right. well on carstereo's sight to determine your Vb or in other words the ammount of volume neede for your enclosure. wich should be the same thing that the manufacturer provided. Well when i fill out the blanks of the calculator it gives me an answer of a Vb of 5.452 cubic ft

heres my specs
SPECS
Displacement (front mount)- 0.128 ft Cubed
Displacement (rear mount)- 0.163 ft Cubed
added volume (Reverse mount)- 0.073 ft Cubed
Qtc=0.43
Qes=0.45
Vas=58L or 2.048251 ft cubed
Fs=28 Hz
Vb=5.452 ft cubed
F3=23.73 Hz
Fb=25.14 Hz
Xmax=13.87mm
recomended sealed box volume=0.7 to 1.0 ft cubed( go with 1 ft cubed)
