altec 211 cabinet

finaly found plans on the 211 explaining the curv of the horn maybe i overlooked it maybe its new to the internet idk i couldnt find it on this site so whatever here it is
braces r 2x3 and 2x4 i think il be able to find out the dimension of the support behind the horn with trigonometry (i think) because the 2 look flush in the front
idk y part of the cone is hidden im sure there is a reason tho im relying on the plans for the 210 to piece more of this pic togeather the 210 plan says the speaker hole is 9 13/16 this pic shows its 8 1/2 so il probly just make this part just like the 210 only with the hole a little smaller also il just position the fiber glass in the center leaving 2 inches above and below it
these cabinets r made very reasonably specific to keep tones flat r these small changes bad? any suggestions on building these?

Translation to English.... anybody? :dont-know::confused:

Ah, ah, ah. The proof that when texting while driving, you do nor the driving, nor the writing, right... ;-)

More plans and pictures.

looks small to be a 211 what r u making
the mm to inch conversion on the horn would be something like 6 1/4, 8 1/8, 10 5/16, 13 1/4 17 1/8, 21 5/16

1 inch = 25,4mm

I think only the US still relies on the akward Imperial system. Even Brits are metric. Canada has adopted it 35 years ago. ;)

Yes, but when I build speakers I still buy 3/4 plywood :banghead:
