looking at the new pics your providing
the raising of the entire floor really won't be as hard as you feel
time consuming, but easy to understand, and easy to execute
your also adding a bit more net interior space to the enclosure by raising sub 3/4" higher out of the box
you may want to use t-nuts and bolt sub in just a thought
take your time , measure twice, cut once , be patient , you can do a very good job
if you want to get crazy and provide even more interior space to the box you can use 2 pieces of 3/4" mdf and raise the entire floor 1.5"
post pics along the way
you can get your T1 reconed by RF i think

I'm currently using these T-nuts. They are only 1 1/2" long though. I'm going to have to purchase something longer.

I believe I'll keep it at raising it 3/4" only.
On the same note, I'd like to increase the inner volume to the max called for by FI. Any ideas on how much polyfill I should add to get the inner airspace up to 1.5 cu ft.?

on the 12" FI Q
sealed
.8 to 1.5 net
at 1.25 your there
with rasing your sub 3/4" your even closer to 1.5 net
i really hate polyfill, it is like a band aid for boxes to small, yours aint to small
since your using bolts - t-nuts- you can bolt and unbolt your sub without comprimising the integrity of your box
IMO i would use no polyfill
if after you feel you need polyfill unbolt sub , fill box, rebolt sub
i think your gonna have ideal net space without poly

you can take your t-nuts to home depot and buy new 2.5" bolts
they actually sell t-nuts and 2.5" bolts at depot
no need to speacial order from parts express
make sure your only using a t-nut once and the bolts once
sometimes the threads get messed up when used over and over

There really is not accurate measure of saying "1 pound of polyfill will add X-number of cubic feet". It is a good rule of thumb to use 1 pound for every cubic foot of enclosure. If you have 1 cubic foot, then use 1 pound and the sub will 'think' it's in a larger enclosure......will it see a 1.5 cubic foot enclosure? probably pretty close. install it by gluing or stapling to the inside walls (all of them, including the baffle that the sub mounts to) about 2-3" thick (fluffy). It should take a full pound to make this happen in a 1 cubic foot box.

+1 on the t-nuts. I've had to cut a bolt off once with a Dremmel because the T-nut began spinning. Ruined the OEM mat. I had to buy a new one to the tune of $85.00...

and maybe another 1/8" in sub height
t-bolts need to go thru the sub, wood , and 1/2 meat threads thru t-nut
2" might work 2.25 " or 2.5" will be ideal

i have had 100 spinning t-nuts in my life at least
always keep a 10" extra hacksaw blade , and i have had to cut zillions this way
but if you hammer t-nuts well into box from the inside, and slowly fasten and unfasten bolts it reduces chances of spin
i have found the more i use t-nuts the luckier i get with the outcome
