BL vs BTL

[whatnow275 0]

Hey, so I was just wondering, which would be louder in a car running off of a powerbass ASA 1500.1Dx amp (both would be 1500w rms at 1 ohm), two Fi BL 12's or one Fi BTL 15?

[Sir-Lancelot 216]

Yes

yes to which one?

Both!

haha well i would rather get one 15 because of the price...and it being a btl...but i'm not sure how it would hit upper bass notes (i think i have my LPF at around 80 or 90)

First off, typically midbass starts around 60hz, sub bass is 60hz and down. ( this is debatable) but most think this also. The two twelves have more cone area than a 15, it is car dependant but typically it will be louder than a single 15. Subbass should never be that high, seems like you're lacking midbass, work on your front stage.

okay thanks, so is there enough difference between the volume from 1 15 btl and 2 12 bls to warrant the $200 price difference? Right now i have 2 10" type r's in a prefab ported box and they are pretty loud. how much louder would 1 15" btl be in a ported box tuned for spl? would there be a night and day difference between the two?

what vehicle is this going in? how much space do you have (volume)?

haha by volume i meant sound output, but it is going into a 2000 ford taurus, so it has a ton of trunk space. my 2 10's take up probably less than a third of it

haha by volume I meant volume (SPACE) in your car for an enclosure, not sound output...

I definitely have the space to put a 3-5 cu ft box in my trunk. how much difference will there be between two bl 12's and one btl 15 on 1500 watts? will there be a night and day difference between the btl and my two type r 10s? also what does "Re: 0.7 Ohms/coil | 1.4 Ohms/coil" mean? does it mean that if i get the dual 2 ohms and wire it in parallel it will actually be .7 ohms instead of 1?

its the voice coils resistance, not the impedance, so don't worry about it. one dual 2ohm speaker can be wired to either 1ohm or 4ohm. Two dual 2ohm speakers can be wired to 0.5ohm, 2ohm, or 8ohm.

Could you fit two 15" BLs?

[Sir-Lancelot 216]

Not with 3-5cf he don't. lol

Is this 3-5cf after sub and port displacement?

What are the maximum dimensions you have to work with in your trunk. Without that little bit of info you are pissing in the wind.

first off i would not put 2 15" ones in, the whole point of going for a 15" btl over 2 12" bls is it would save me about $200. the website says i have 481 liters cargo capacity, its a pretty big trunk. i would like to know if its worth getting the btl 15 in comparison to my 2 type r 10s

481L of cargo capacity means shit! If you built a 481L box would you be able to fit it into the trunk? Prolly not. Get a tape and do some homework. Measure your trunk. If you cant do that then there is no help we can give you.

To answer your question, yes 1 15" BL would be "better" then your 10's if you have the space to give them a proper enclosure.

^This.

There are people who spend thousands to gain a few tenths on the meter, so if $200 is worth the gain in output is up to you. Either way if you only have 1500 watts just get 2 SSDs or one BL, this will save you even more money. I'd go 2 SSDs because from your experience level you'll be better off with 2 subs sharing that power. If you plan to upgrade your power down the road by all means do BLs, but with your current amp they aren't necessary.

what do you guys think if the I Heat Ring? worth getting or not?

It's worth reading about it in the Fi technical section
