LOL ,I'm new myself ,just lookin for some advice.I,m goin to start trying winisd and horn resp soon but its looking kinda complicated.I did some trial bass reflex for the same speakers and it worked great but want some different looking subs.
looks like a hybide.
basreflex horn combi.
you should be able to model this with horn responce.
where have i seen this model before

Yeah it' very similar but I'm a lil bit confused with hornresp since I'm new at it so I was wondering if to just try building one and see how it goes but more work also..
Each driver has the recomm. volume and port size for a bass reflex ,I am not sure if it will work positioned like this to minimize distortion.

ah, a strange kind of "ripole"
mind you
its pro sound "subwoofer"
doesnt go so low, but instead louder
not really a domestic hifi thing
more in the party disco techno direction
look up ripole, which is a folded dipole
another "variations" is H-frame
plenty info on those

Thanks,but I need translation,haha ,I've seen the ev manifold but wanted a different look.I need to know if a box looking just like this can be tuned by port or size to perform just as good but with the same SHAPE.Hope I don't sound silly.
I guess I'm too lazy and busy to do the math.

The EAW sb1000 goes too low for me,I will need at least a 4 stack to go as loud as my two bass reflex 2 18" enclosures that I have now with the same selenium drivers.Never tried the manifolds but as I said...A different look!
for a groovy look and cone control one might try the 5181 K-coupler

Wow!!!Thank you soo much,this looks great!Just what I'm lookin for .If today was'nt Sunday I'd be rushing to the hardware store to order the plywood for this .I"ll post the pics soon as I'm finished .
THANKS AGAIN!
THANKS AGAIN!
That zip file is damaged.
Anyway, it's only a horn above 100hz, probably has a nice peak between 150hz~200hz.
"Thanks,but I need translation,haha"
You didn't give a port dimension in your first post. I figured it out for you, 10-5/8" tall, 3" wide, by 8-1/2" deep.
Use a 40hz high-pass filter, with a Q=1 if adjustable.
