large sealed?

[Etac 10+ year member]

ok i built my box to the recommended specs... 1 cube per speaker.. so i got a 2 cubed box...

anyway i never ran a sealed setup before, and i like it overall, it does lack depth a little but it sounds great and my goal is defently SQ based... so

i modeled my sub/box in winisd with the recommended specs.. and it says my qtc is like 1.2+ which seems high.. and also has a peak from 50-60ish... and drops very quickly after that

now if anyone read my other post about SQ sub stages.. i read alot of IB setups are common...

now im not gonna be able to do an IB setup... so i did some more modeling in winisd... with about 5 cubes... i get a qtc of around .89.. and a much flatter and decently deeper response... and since this is more towards an IB setup so i was thinking about doing it...but i've also read posts on how making large sealed boxes ****... and its not a good idea

so i was just curious if anyone wants to add anything.. i dont feel like wasting my time if its gonna turn out to be a disaster...

if you have a subwoofer that is suitable for IB then the larger the box the more the slope will represent an IB setup. If your sub is not able to operate in IB it will sound like poo

just the design of my trunk where it connects to the back seats is like cheap plastic and would require alot fo work to seal that part up and remove all the rattles it would make

if the sub would sound good in IB, it would sound good in a big sealed box.

im not sure if it will but according to winisd it seems like it owuld love a large sealed box... it has a pretty high QTS at .51 bbut its vas is also high at like 120.... its xmax is only 10.5 mm but its xmech is 22 (one way)

IB isnt out of the question... i might take a better look tomorrow and see if i could work it out... somehow

if it has a high vas that would lean towards a bigger box, and means it will be able to hit the lows well without bottoming out as easily
