when RE says that a 12"sx should be in a 1.9 cu ft box tuned to 32hz does that 1.9 include or disclude the port and sub displacement? in other words sould it be 1.9 cu ft total? or bigger?

this is what i was gonna do
http://www.accelerator-pedal.com/ported-box.asp?Ew=32&Eh=16&Dia=6&Xmax=21&Vd=0.1 6&NumW=1&Vb=1.9&Fb=32&Qts=&Vas=&Fs=&CE=0

look ok?

or i might tune it to 30 hz
http://www.accelerator-pedal.com/ported-box.asp?Ew=32.5&Eh=16&Dia=6&Xmax=22&Vd=. 16&NumW=1&Vb=1.9&Fb=30&Qts=&Vas=&Fs=&CE=0

or mabey even this?
http://www.accelerator-pedal.com/ported-box.asp?Ew=32.5&Eh=16.5&Dia=6&Xmax=21&Vd =0.16&NumW=1&Vb=1.9&Fb=30&Qts=&Vas=&Fs=&CE=0

what do you think?
would they work?
which is best?
i like the last one because of some simple measurements
what do you think?

i like the top 2 because they have slighly more port area. they all work though. that is the kind of 1.9 cuft they are tlaking about. except, well, find out what the woofer disp. is and add that to 1.9. then say the disp. was .15cuft(i dont really know) set the net volume to 2.05cuft and choose wether you want 30 or 32 hz tuning.

Ummmmm, I'm thinking that 30hz is too low. In car the frequency will tune much lower thus you will be losing quite a bit of amplifier power to absorbtion. JMHO...Polo. :-)

32 sounds fine to me, but sould i make it a little bigger than that? mabey like this
http://www.accelerator-pedal.com/ported-box.asp?Ew=32&Eh=16.5&Dia=6&Xmax=21&Vd=. 16&NumW=1&Vb=2.25&Fb=32&Qts=&Vas=&Fs=&CE=0

or if i wanted absolutely no room left in my trunk...
http://www.accelerator-pedal.com/ported-box.asp?Ew=32&Eh=16.5&Dia=6&Xmax=21&Vd=. 16&NumW=1&Vb=2.5&Fb=32&Qts=&Vas=&Fs=&CE=0

actually, that came out way simpler, i might just do that, barely any bigger anyways

ah, what-the-hell
http://www.accelerator-pedal.com/ported-box.asp?Ew=32&Eh=16.5&Dia=6&Xmax=21&Vd=. 16&NumW=1&Vb=2.75&Fb=32&Qts=&Vas=&Fs=&CE=0


what do you think about those, i like the last 2, but is 2.75 cu ft too big?

what do you think

btw
the drive displacement is factored in on this calculator

this is what im goin with
http://www.accelerator-pedal.com/ported-box.asp?Ew=32&Eh=16&Dia=6&Xmax=21&Vd=.16 &NumW=1&Vb=2.5&Fb=32&Qts=&Vas=&Fs=&CE=0

but where should i put the sub?
i would think on the left side of the red board (next to the port) so the air circulates throught the whole box, but the single sub diagram on RE audio has it on the opposite side? does it matter?

im not sure exactly what would be the difference, but everyone always does it on the oposite side of the port. i think thats where it would look best too, id just do it that way, on the right side.

ok,
but i think i changed my mind on the box cuz i want a little more port area just to be safe

hows this look
http://www.accelerator-pedal.com/ported-box.asp?Ew=32&Eh=16.5&Dia=6&Xmax=24.75&V d=.16&NumW=1&Vb=2.5&Fb=32&Qts=&Vas=&Fs=&CE=0

i just made the xmax higher to get more port area,

if this looks ok thats what im doing for sure

no the liquid nails has to dry, thats pretty much all i did today, actually i dont even have the sub :-) i just wanted to compit to it because if i didnt i would change my mind, cuz im an idiot.

it was fun building though, all i had was a circular saw and a drill so it was kinda difficult. came out clean considering that thought.

i think i might drop one ov my vmax's in just for fun tomarro

ill proble get the sub next week or so
