t215 rockford vs fi bl15

[caddyon20s 0]

im not that experienced with subs, correct me if im not mistaken i can give both subs 3.25 cu ft separate from each other, tunne each side of the box at lets say 34 hz does that make sence, in ur case what would u do keep the t2 15 and get another one like it, or get another fi bl15 thanks again

Hi, im going to build a box for my bl15 and rokford fosgate t2 15 subs, whats is the good or bad of making a one chamber box for two subwoofers, is it better to put a divider in the center of the box and make two different vents, can i use two different subwoofers in a single chamber box, experts please help.

I say another BL. But your asking that question on Fi's forum so most people are going to say Fi. Go to realmofexcursion.com and ask that question for different opinions.

single chamber always hits harder.

Given properly-made ports, it shouldn't matter...

If you Bass Race or dB drag it does. One chamber with multiple subs means the air is pushed out with more force then a sub to each chamber.

YOU SAY sell the t2 why would a bl15 be louder than a t2 ?? i mean a t2 is supose to be a great sub, im new to fi audio please tell me what is the difference between the two subs and why would a fi be louder??

Looks kinda funny running two different subs but that would work except the bass will sound a little funny cuz one will hit differently then the other. Here is a forum comparing a T2 to the Q if you

as mentioned b4, cancelation can be a serious problem with mixing as well, if you are not sure what we mean by the term " cancelation" let the search feature do the work for you and read all the stuff you find pertaining to it and let it soak in..

Rodrig,

Bass cancellation can occur in a few different ways:

1: Mixing different size woofers

2: Mixing different impedances(ohms)

3: Not providing both woofers with the exact power and signal

Honestly it really is hit or miss, sometimes it works and sometimes it don't.

Ultimately we recommend using the same woofers across the board, and if for some

reason you can't keep them consistent then at least keep them in separate

enclosures.

this is my dual subwoofer box please tell me if im wrong, the subwoofer displacement is .176 the materials is 3/4 thick thanks.

[theabunai 3]

where did you design this at ??

[jockin my styLez 0]

hey i started that thread on ROE

on a side note..no

[ANeonRider 3]

It's terrible, start over.

[ANeonRider 3]

Well, yes. It was quite obvious from the start. But, at least he fits in with the majority of people that fill this world.

Yes he is. And he doesn't like to listen.

[mcbuggin 1]

I got a 160 amp 1 wire from ace alt off of E-bay and it really does the job for me think it was $130 or something how ever it only runs the amps in my bug

[caddyon20s 0]

i went to this website http://www.2k4civic.com/portcalculator.html i did all my calculations subtracted the speaker displacement wich is .176 put my port dimenssions and thats how i got it. i did my calculations to a rockford fosgate box this one http://www.rockfordfosgate.com/scripts/rig...2%3Afaqs.faq_id and after doing the same process, it game me 38 hz and port length 22.5 same as rockford 15" sub

and by the way, i asked this to rockford fosgate people, experts, this is what they say if u didnt read up above. Bass cancellation can occur in a few different ways:

1: Mixing different size woofers

2: Mixing different impedances(ohms)

3: Not providing both woofers with the exact power and signal

Honestly it really is hit or miss, sometimes it works and sometimes it don't.

reason you can't keep them consistent then at least keep them in separate

enclosures.

and my subs are gonna be 15" both and they are gonna be dvc 2homs both.
