Hi
if you have the time pleas look at my design
T/s
the room is 6x20x3,5 meter
thanks

An externally hosted image should be here but it was not working when we last tested it.
the room is 6x20x3,5 meter
thanks

An 'Adire' alignment for this driver using published specs appears to be 71.65L/17Hz, but unless you have a lot of room and/or corner loaded gain or live in an apartmemt or condo, I do not believe you will find it adequate for HT, though should be fine for music with some EQ shaping to flatten in-room response.
WRT your extended Fb design, it is OK as is, but considering the intended app and the driver's specs (if reasonably accurate), I would put it in a Vb = Vas/Fb = (0.707*Fs) ML-TL, with the VCs wired in parallel to keep Le low.
Suggested ML-TL:
L = 62"
width/depth (CSA) = 270.6"^2
driver down from top 24.63"
5" diameter x 12" long vent near/at the bottom
0.2-0.4lbs/ft^3 stuffing density

You sure had me fooled! Since at a glance I do not see how to explain it better, I am not sure what is unclear, so please ask specific questions.

Sorry, I do not do drawings anymore, typing a response is hard enough, and to think I started my career as an achitectural, electrical draftsman and topography map maker.
I have accumulated a few CAD programs, but have not yet got around to learning how to use any of them. Anyway, it will look similar to this except with different dimensions and will require some bracing: http://www.geocities.com/rbrines1/images/FE167E-MLTL/FE167E-MLTL_Simple.jpg

ok, now i see it.
But what do you meen by : "width/depth (CSA) = 270.6"^2"
width = 270.6"/depth = 270.6" ?? Thats big !! i hope you meen somthing els
Thank you for helping me

CSA = cross sectional area, so if you want to build a square 'pipe', then 270.6^0.5 = ~16.45" square (inside dimensions). For other width/depth sizes just divide the dimension you want into 270.6 to get the other dimension.
You are welcome!

You are welcome!

CSA is cross sectional area, that i never learned in english 😱 and i finished with school 🙄
What will this be tuned to ? I think that i will build it and try it out.
'CSA' is an abbreviation that would not be taught in school, except possibly an engineering course, but learned on a forum such as this one.
