no.

funny uhh. back to the subject we are not here to argue, can somebody desing me a box i have 42"w 18"h and for deep u can go as much as 35"d i need a dual chamber box please, the speaker displacment is .176 and i need at least 3.25 cu ft net per subwoofer tunned at 35 hz, ok here it goes everyone anybody willing to pay that really knows this i will pay u 5$ if u have paypal. i can send u a payment thank you very much.

I say do what you're gonna do anyway. No matter what the guys here say, I think you've convinced yourself that you want to do it. So when it sucks balls you only have yourself to blame. And if it sounds good to you then and things don't get messed up then hey you can tell us we are all wrong.

Just wanted to make sure...your subs do have the same impedence load on them? 2 Ohm's each?

On second thought, if you have a seperate amp for each sub then it really shouldn't matter, nver mind.

no.

That kind of attitude won't get you far here...thanks.

both subs are gonna be dvc 2homs so yes

You can't get a 2 ohm load out of a single 2 ohm DVC sub...either 1 or 4, for a combined 2 ohm load, maybe.

Okay, let's keep it civil!!! OR ELSE!

If you ask for help that you really don't want, then prepare to get flamed. You're only asking for it so there is NO reason to get upset.

Ok, Now that i've cleaned this thread up.

To the OP, regardless of what you may think. DO NOT mix subs. Period. I'm not going to say it again, we are telling you what is best. Each and every different size/series of woofer has a different frequency response. If you mix the rockford sub and our sub you are going to have SERIOUS cancellation issues, and not to mention it is going to sound like complete crap. Don't get the mentality of "i'm gonna have the best of both worlds" because that's not how it's going to work. Either ditch th rockford sub, and get 2 of our subs, or ditch the idea of getting our subs and buy another rockford sub.

It's not about the impedence of the coils (dual 2ohm) that is totally irrelivant. In comparison you are attempting to breed a bull dog and a cat and come out with a bullcat. You can't do that. Genetics won't allow it, and the same thing goes for the audio world. Simply do not do it.

Now, all the threads that you've made i'm merging into one. You don't need to make a new thread every time you have a question, you can post more then one question in one thread that you make.

Thanks

theres alot of "no" up in here....lol

NO

A lot of hidden mod edits is more like it

i yi yi this is giving me a headache

After having read through all of this... Im not saying what the RF tech said is incorrect, but it isnt telling the whole story either. Just because a driver is the same size, same nominal impedance, and in separate but equal enclosures/chambers, does not mean it will work properly or optimally. Yes, it will work. But not as good as it could.

To me it is like taking a 35" tire off my jeep (15" wheel with a 35" off road tire) and replacing it with a 30" bling wheel with an ultra low profile tire with an overall tire diameter of 35" as well. Now if the bolt pattern fits, you have similar offset so it wont rub, and the same OD... it will work. I can drive it... But when I try to hit the rocks or dirt, problems will arise.

There are MANY different aspects to a sub and how it reacts in the same enclosure with power. Its all of these other things, suspension, impedance rise, Q values, and on and on that will determine how well things will work together.

My answer is if you want to build a dual chamber box that seems optimal for either sub, then put both in and wire them separately to try them 1 at a time to see which you like better... then pull the other out and replace it with what you prefered. Doing this simply to see which sounds/works better for your application is fine. But I wouldnt run them at the same time. Odd things happen with different back EMF screwing with eachother at different frequencies as well as with the amp. Its simply not good practice. Will it work? Yes. Should you do it? No.

Thanks,

well the problem is that i just ordered a FI BL15 i have a rockford t215 right now, and i didnt no nothing about this. i can sell my t2 faster than hot bread sells becuase it pounds really good but i dont wanna sell it till i try the fl15 so I AM A wait try both subs like my friend said up above wich ever wins ill get another one of that kind. thanks a lot scott good asnwer.

You better not use the same box for both of them..

Each one uses different specs to determine total enclosure size and port size. You can't just build one box that "might" work for one but not the other and expect them to compete for your attention so to speak.

that is a good point, right now i have a 3.25 cu ft to my rockford wich is what a t215 need, mmmmmm i think a fi bl15 need from 3 to 4 cu ft right? well 3.25 should do ok on trying to compare the subs dont yall think.

You can't get a 2 ohm load out of a single 2 ohm DVC sub...either 1 or 4, for a combined 2 ohm load, maybe.

yes i know i have two ams two channel, thats why im getting two subs each is gonna be dvc 2 ohms so i can give a load of 4 ohms bridged to my two ams,

this thread is just a waste of time

just do what you said you were gonna do and just leave it at that..

come back with results of your testing of the 2 subs next time
