look i dont need crutchfield to tell me this, i already know.......but this is for YOUR info.

The type of bass you get from your component subwoofer doesn't depend on the woofer alone. You'll need a strong, tightly-constructed enclosure for optimum subwoofer performance. Speakers without an enclosure can't deliver full bass because the sound from the back of the speaker can cancel out some low frequencies emanating from the front of the speaker.

Using our box-building accessories, you might choose to construct your own box to create the enclosure size that you want. However, unless you have excellent craftsman skills and a solid understanding of enclosure volumes and other technical terms, you're better off purchasing a convenient, professional-looking pre-made enclosure.

Different types of boxes will produce different types of bass:

Sealed boxes: For deep, precise bass

A sealed box is an airtight enclosure housing your subwoofer. A sealed box is best for any music that demands tight, accurate bass. Expect flat response (not excessively boomy), deep bass extension, and excellent power handling. Since a sealed enclosure tends to require more power than a ported box, use an amplifier with ample wattage for optimum performance.

Ported boxes: For forceful bass

Ported boxes use a vent (called a port) to reinforce low bass response. You get more output than you would from a sealed box at any given amplifier wattage. Some people prefer the sound of ported boxes for rock, heavy metal, or any hard-driving music. Ported boxes can deliver deeper bass than sealed boxes, though they need to be much larger than sealed enclosures to accomplish that.

Bandpass boxes: Maximum slam

Bandpass boxes are a special type of ported box designed for maximum slam. The woofer is mounted inside a dual-chambered box (one chamber sealed, the other ported), with the sound waves emerging from the ported side. The sound that comes out of the port is extra loud within a narrow frequency range.

Because bandpass boxes are super efficient within that range, they tend to boom. Their aggressive sound is great for rap, reggae, and hard rock. Not all subwoofers work well in bandpass boxes, though; consult our product information or call one of our Advisors to be sure.

Free-air subwoofers

A free-air system consists of woofers mounted to a board attached to the rear deck or placed in the trunk against the rear seat. The trunk of the car acts as an enclosure which houses the subwoofer and isolates sound from the back of the speaker, solving the sound cancellation problem of subs without an enclosure.

Free-air systems save space and have flat frequency response. The woofer must be specifically designed for free-air use. The lack of a box makes them more convenient to install, but their power handling levels are usually much lower than their boxed counterparts.

when i put the 10 on the tailgate and bumped it, it was just a sub out in the open, cancelling itself out. Its free air in the fact its sitting out but its not a "free air" configuration when talking SPEAKER BOXES. A free air sub is NOT designed to bump without a baffle, it is designed, as Jack said, to be either in a trunk or in a super large enclosure where it has little to no resistance behind it. It still needs to be on a baffle and have the front/rear seperated to eliminate cancelling.

you youngsters can say ANYTHING you want, you are wrong.......IB and Freeair is the same thing. Dont worry, i wont bann you for being wrong though. In the car stereo world, a woofer designed for "free air" applications are made to be placed on a baffle and your trunk is actually the box. The front wave and rear wave are seperated by that baffle therefore you get bass and not cancellation.

I totally agree with meade.

free air is just a " slang" that is easier to understand as compared to " infinite baffle"

but when u lay the woofer on the floor and u power it up, it TOO is also called free air.

so 1 term can refer to 2 kinds of application

just like the term " weed".

weed = pot rite?

but weeds are also those shurbs that grow in ur garden? 1 word, 2 applications.

from my understanding, free air application is commonly used in SQ setups. you'll mostly never find a hard bumping 140+ to 150+ setup on a free air application.

the benefits of free air setups is that the sub is able to get insanely low and very easily. thus you'll be achieve the low fill without much effort.

But the cons abt free air is that it will definitely lack the " thump" as compared to a sub in an enclosure if i'm not wrong wrong, power handling wise, it'll not be as strong as that of a sub in a box.

but good thing is, u save space in the trunk!

Lastly, when i mean SQ, i mean REAL SQ, where the sub is more of meant to be felt slightly, but not heard.

ok, ok... good read. I think most data that has been out there for a while and not updated will say the "old" definition. I think that over time, sometimes words uses are changed, and I feel most of the time today, when someone says "free air" they most likely mean sitting on the floor or tailgate. I think most literature will take time to catch up, and I agree that free air at least was interchangeable with infinite baffle. But I would be willing to bet, 5-10 years from now, litterachur will catch up.

I'm not tryin to argue, this is all IMHO, I just think that what everyone considers something to be today means more than what people may still write down.

YES! I totally agree! Neither is wrong, and slang is to blame. Free air WAS IB, now it's 1:IB, 2:slang for WTF!

[meade916]

agreed, slang is to blame....i was also guilty at one time
