Ok so i have made a probably 50 different draw ups for this. Well sort of draw ups. I have recalced the box over and over just playing around with numbers on paper and comparing to my enclosure calculator.
This is what i have came up with that is to my liking. Again im looking at about 2500-3k(probably about 1500-1700 after rise and voltage drop) and will probably end up getting more power im sure lol. Im always changing something.
Enclosure Specs -
HD15 W/7.5" Aero W/2" Ext
29.5L x 16H X 22(outer dims w/o double plates)
Gross - 4.82
Displacements-
Sub Dp - .15
7.5" Custom Sono Aero X 17" -.43(2"s will be external so inside displace will be .39)
Vertical 2x4 @ 14.5 - .044 ea(There will be 2 top to bottom = .088)
Lateral 2x4 @ 20.5 - .062 ea (There will be 2 Front to back = .124)
45's @ 2"L x .75d x 14.5h =0.23 ea (There will be 4 in each corner to round it a little = .092)
Total Displacements - .844
Port Will be 2" External from ( 15"s inside and 2"s out external)
Port Area(7.5" sono)- 44.18
Square inches Per - 11.045
Box Tuning - 36hz(36.45 or so)
Net Cubes - 4.00 (3.976 actual)
The reason i have a 7.5 Sonotube is because some of them are actually only 7.5 and some are as big as 8.5. Im going to take a tape measure and hunt for a 7.5 because that fits what i want lol.
The 36hz tuning is a little different for me, i usually go about 40hz, but i wanted to be able to play a little lower with this so i played the numbers to drop the tuning a couple of hz
