I think could be useful the input data for hornresp of this cab. so here's

Bass section
s1=1350
con=22.5
s2=906.5
con=23.5
s3=1912
vrc=42
lrc=20
atc=3300
vtc=6393

pay attention to these tips
-subtract cone volume and magnet volume of 2 driver from vrc
-add cone volume of 2 driver to vtc
-put 2 driver in the driver arrangement menu
-in the spl screen, tools menu,directivity, reponse put 69 degree

midsection
s1=144
con=25
s2=1175
vrc=4.46
lrc=10
vtc=216
atc=550

pay attention to these tips
-subtract cone volume and magnet volume of driver from vrc
-add cone volume of 2 driver to vtc
-in the spl screen, tools menu,directivity, reponse put 0 degree

Any chance of getting the plans in inches?
by bitzo
divide all the quotes by 2,54 you get the inches.
divided all the quotes by 2,54 , get the integer value and now substract it to the quote divided by 2,54. now convert this value in your crazy imperial fraction.

A pretty stupid question but...a don't realise it since now...where's the 8" mid horn access pannel ?
by bee
on the 2 i built i put the panel on the top of the box, not alot of room to load...... drop in the driver then bolt in.

Is it possible to make this cab with only 1 15" driver to make cab shorter?
i always thought the 8" section was made removable so you just access the driver by removing the horn.

and nate, it seems like you might be better off rethinking the cab.. if you don't like it as is.. then using the 8" section and a 1" cd and horn of your choice over some other 15" section may be what you're looking for...
by bee
on the original plans the horn is made from ply, on the ones i have seen, and built it was loaded from the top..... on the fibre glass versions then yes, just undo the horn and slide out......
by bee
i should of said the top angle piece of the rear chamber, i screwed in at the correct angle you need to remove this too. to creat a seal i used sillicone.
by bee
on the plans i have there is no referance to loading the 8" horn, but on the new plans posted here it states the horn is bolted in to place and can be removed, to load. I allso noticed the 15" horn section differs to the plans i have. Im assuming the plans i have would be for the original version and the plans posted hear are the updated ones...... smiley16.gif
by nrpinc
I like the box the way it is. I think its a great idea. I was asking if it could be built with only 1 15" driver instead of 2 thats all. i don't want to change the 8" or 1" section, I was just wondering if it would be possible with 1 15" driver.
