k.. but if i make it 12 and 8 then the width of the port at the top part will not be 3"

i calculated that its gotta be 12.5 so that the top part of the port remains 3"

and if that part is 12.5" the other port part should be 7.5.. right?

hey a quick question.. around the sub where it screws into the wood... do they screws go straight into the wood or wat?

well u right about the 12.5 and 7.5 i just didnt want to get into the half inch measurments for the port so i kinda rounded them off.

yah screws go into the wood

got any other tips? wat kidna screws to get?

i put a screw every 5" right?

alot of woodglue... wat type of glue is good?

Any high quality carpenders glue will work... its usually a pale yellow instead of white...

I've also used (forget brand) white glue that is extra thick... worked well, dosen't run, and cures faser...

Also, any good carpender will tell you that the screws are only there to hold the wood together unill the glue dries...

there is no need to use 10,000 screws for one box like I see often enough... [img]graemlins/laugh.gif[/img]

what he said

any carpenter glue from home depot paint section will work.

screws only hold it till glue dries but for high spl boxes screws are good. i use 8x1 1/2 inch wood screws.

how far apart they are is up to u, i never measured, just screw them in. also pre drill with a small bit before u screw.

k thx guys. im off to home depot now :D

we'll see how my first box turns out hehehe. ill post here as soon as im done anyhting and everyhting..


wish me luck bye

Don't forget to use gasketing foam around the speaker rim to seal to box....closed cell works best.

Also, T-nuts and matching bolts are the catz azz for mounting the sub to the box b/c they allow repeated removal/re-install of the sub w/o having to worry about stripping the wood...and you can really crank them on as tight as you pretty much want

BOX IS DONE!!!

i just need to sand off all the excess glue and crap from the outside, and then put the sub in it and drill holes and screw it in, and then drill a hole in the back to let the speaker wires out and then hook it up and listen and setup the amp and stuff.

thansk for all your help guys ill let you know how it sounds tomorrow morning.


one question though.. how do i setup my amp?


There are three knobs and one switch.

knob 1: BASS - 45Hz (0 to +6)
knob 2: BASS - 30Hz (0 to -18)
switch: xover 12dB - (80Hz, full or 120Hz)
knob 3: Gain

wat do i do and how do i do it?
