my 16 10s design

[nuboot 10+ year member]

well heres my first ever design using sketch up each of the sides are 26h x 15w x 45d for 8.3 cubes

and the opening area will act as the ported area and the measurement to the area is 26h x 25x 45d so iits about 650 square inches of port area and tuned to around 43 hz

so does that look and sound right

hopefully this box hit the lows do a possible hair trick and still put up decent numbers

In what kind of vehicle?

clam it so the pressure will go foward instead of sitting in the back of the box

how did you determine it was tuned to 43Hz?

op hes saying angle so the back comes to a "V".

then try to figure tuning. glwt

thats a 4th order bp have you plotted it in a program ?

a bp has a tuning range or bandwidth like 30 -55hz not a single number like a ported box

help plz i thoought i was doing something lol guess im not thanks for all the input

a 4th order bp is one side sealed one side vented

http://www.diysubwoofers.org/bnd/4thorder.htm

the sealed are behind the woofer on the right and left are the sealed section and the long "tunnel" is a port 26"x25" right being 45 "long that is the vented side

toss the t/s parameters in winisd or a sub program and see i bet its tuned really low like 15-30hz thats just a guess though

do an ported clamshell tuned around 28hz that would be more than what you are looking for!

the two boxes 1 on the left 1 on the right they are sealed and the tunnel part with the loading wall is supposed to be the ported area. i guess thats what u just said. im confused now lol

help?

 

[psychoacoustics 10+ year member]

yes sorry thats what i meant

the sides are sealed boxes with 8 woofers each?

and the tunnel is a ported chamber

 

[nuboot 10+ year member]

thats what i was going for
