There a bit different. You can easily get more SPL with a ported box. IB will slam good on the lightest notes and sound goood and get low. I vote IB just because i like it so much, but it dosn't mean i compare it to a ported style.

You can setup IB subs for a very linear and flat response. The subs usually have low inductance, and they can still slam nicely and sound goood. Cone/excursion is great like PD said in your other thread.

Go for it.
i was shocked to hear that i do not have to be seriously anal about sealing up the trunk AND that i can port it. Do you by any chance know how to caculate a port for an IB enclosure?

You don't have to be anal, but the better the seal the better off you are. Porting a IB, thats not a IB then. Just a large ported box. Something I wouldn't do. Either run ported or run IB.

Pros for Ported- Louder, handle more power, Can tune for your response

Cons- Heavy box, takes up more room (foot print), has more of a peaked response comparted to IB.

Pros for IB- Don't need alot of power, easy to build, super flat response, takes up less space (foot print).

Cons- Lower overall spl, lower power handling.

you have those backwards. Ported boxes are smaller, IB takes up more room.


but yea, you cant port IB, its really just a box with at least 10x the reccomended seal size, you just want to separate the front and rear wave.

IB does take up less room, IB in a car is just a baffle using the trunk as an enclosure. in a house you have a much harder time doing that so you make an "infinite baffle" around the sub to trap the rear wave

How is a ported enclosure smaller than IB? There is no enclosure in IB, just a baffle separating the front and rear waves.

a true infinite baffle is a huge sealed enclosure, in car audio it would take up way to much space so we do it a different way to separate the waves
I completely agree...it is difficult to achieve "true" IB in a car. Only thing that comes close is using an aperiodic membrane, but then it technically isn't IB anymore.

if you feel like putting things inside your IB setups "box" then its less room,
but if you have a tiny car and need 20 cubes to do a proper IB setup, its bigger when a ported box might only need 4 or 5 cubes

IB is not a box, it is an alignment. I don't think I have ever seen an IB setup in a car that have 10x VAS in an IB setup. I can go back through magazines and dig up World Championship SQ installs using IB alignments and I guarantee none of them have 10x VAS.

I see what you are getting at, but you are arguing a moot point.

I know its not a box, but there is not infinite in a car so its pretty much a big sealed box.
but as long as we both get what each other is saying.
