Sub upgrade with 2k to spare

[JoeK 10+ year member]

I have an Fi BL 15 now and i wanted to upgrade to a better sub (or subs) that will run on 2k @ 1ohm. My maximum space is only 3.2cuft so it needs to work within that range.

I prefer lower tuning but im fine @ 32hz

I was also told that 2 12s would work better than a single 15, but 2 12s of high quality will be twice the price of a single 15; but what do you people suggest?

if your looking for new then either xfl 12s or one really good 15 ,like lvl4 maybe or something along that line

1 sub i could go for a XL m2, i heard they are ~$500 shipped; i was just told 2 12s would work better.

I like the idea of a single 15 more if itll sound good in my box

2 12s will get down over a single 15 with both setups in proper box

how much port area are you running on that box?

I did ****** measurements (box was built by a pro tho) and its about 3' wide by 10.7' tall

in 3.2 cubic box the 15 will get lower than the 2 12s

that is about 10 sq in per cube, a little on the thin side..you say 10.7" tall..are you doing sub up/port back. or port to the side?...and you have at least 3" of clearance between the port opening and any trunk walls? You know where I am going with this, I am trying to figure out why that Fi does not sound good.

It does sound good! Its port firing backwards and sub up

that bl should be able to make you pretty happy, if its not just an enclosure issue, possibly try a pair of 10's. will give you more motor force and depending on the sub can easily like a smaller enclosure.

hmm...sounds like you are just wanting more spl. Have you thought about running a couple of 12's sealed off from the trunk with subs/port forward firing through the back seats? I mean, I do not even know what you have back there, other than it is a trunk car, IIRC.

'a couple of 12s' is the problem. Which 12s would be louder than my Fi that meets my space requirements. Idc about sealed or ported if it all sounds right. Back seats also do not go down
