[billabongcr 5,000+ posts]

I designed a box on RE's website using their new box design program. Came out:

Box Width: 35

Box Height: 19

Box Top Depth: 10

Box Bottom Depth: 10

Wood Thichness: .75

Square Port Height: 17.5

Square Port Width: 1.5

Square Port Lenght 1: 7.75

Square Port Length 2: 8

Total Port Length: 18.75

Square Port Diameter: 5.781222885

Square Port Area: 26.25

Square Port Volume Internal: 492.1875

Square Port Volume Displaced: 503.4375

Box Volume(Ft3): 2.592

Box Volume(In3): 4479.6875

Tuned Frequency(Fb): 34.4507186306804

Box Bottom Plate: 35 x 10

Box Top Plate: 35 x 10

Box Left Plate: 9.25 x 17.5

Box Right Plate: 8.5 x 17.5

Box Back Plate: 35 x 17.5

Box Front Plate: 32.75 x 17.5

Port 1: 7 x 17.5

Port 2: 8 x 17.5

Or someone here on CA designed a box for me..came out:

Number of drivers : 2

Box type : Vented

Box size : 2.500 ft^3

Tuning frequency : 37.00 Hz

Vent : 1 vent(s)

26.50 in length for each

2.50 x 17.50 in rectangle

which would be better to run my 2 SSD 10s? both subs will have about 1k on each woofer. which of these box designs seems more accurate for my drivers. ive never really did a box design before..and my calculations comes out closer to one than the other..i just want to see who agrees with the one i think i should go with

so..RE or CA member?

[billabongcr 5,000+ posts]

how did i mess up

 

[billabongcr 5,000+ posts]

goin to get the wood in a half hour..last chance for criticisms

why so shallow...and MAKE SURE the subs will clear that port....with it being so shallow.

 

[billabongcr 5,000+ posts]

thats why im thinkin the RE one..the inside port wall is shorter so it clears the subs

i wish i could just cut a few pieces of wood and build a box lol. having to build in trunk ftl.

i usually have to take my seats out

ok i did some more measuring..with my subs an inch apart and 2 inches from the end of the box..my port wall on the inside will be exactly to the outside perimeter of my sub..leaving the actual port wall about 2 more inches away from my motor on the inside. good?

if that makes sense

ok, start over. whats the mounting depth of that sub? whatever it is subtract .75(front baffle), and then it should be a good 2 inches away from the port wall

 

[billabongcr 5,000+ posts]

maybe this will help

sub mounting is 6'

port=1.5. that leaves 7.75''

so i have 1.75'' of clearence between port and sub

if i make the volume of airspace smaller..will that give me more room between port and sub?

or should port go in middle

im sure you'll need a bigger port, increase the port area around 96"sq to 100"sq to lower your port noise to the none audible zone.

h/o ill whip it up how it will be exactly in 3d cad
