Freeair????

Question

My woofer says it can be installed as a freeair woofer. What does this mean and how does it work, ie, install etc...?

I know it does not need an enclosure. How would it wount and sound?

1000 watt subs are not weak...

Answer 1

Free-air means they can operate without the backpressure of an enclosure, however, they won't produce bass to their fullest potential out in the open.

Answer 2

A proper free-air install gives you more accurate bass with great extension. Boxes will usually make the subs hit harder, but if the box isn't just right, you run the risk of unwanted resonances.

Here is some info :

An infinite-baffle system has no separate enclosure,
per-se. In effect, it uses the trunk of the
automobile as the enclosure. When installed properly,
this system acts like a large sealed enclosure,
without occupying any trunk space. In
theory, the trunk is so large, that it’s effect on the
woofer’s frequency response is insignificant, and
the output is essentially the same as the driver
alone. Virtually all the sonic characteristics of
sealed systems are valid for infinite baffle installations.
Installation time is typically less than other
systems because no enclosure is constructed.
Excellent performance can be achieved this way,
at the expense of maximum SPL.
This is because all of the other enclosure types help control woofer cone motion at low frequencies
or high output levels. In an infinite-baffle installation, the woofer’s suspension and motor
assembly are the only forces controlling the cone motion, so high signal levels are more likely to
cause woofer bottoming.
To use an A-series woofer this way, we recommend a baffle board be constructed from at least ¾”
thick MDF (medium density fiberboard). The baffle is most commonly mounted to the underside of
the rear package shelf, or behind the rear seat. It should be sealed against the vehicle structure
with gasket material, so that it is completely isolates the sound from the rear of the woofer from
the sound from the front. If there is a solid metal panel between the woofer and the vehicle
interior, it must be perforated for the sound to get through. Do not cut large areas of metal out of
the shelf since it acts as a structural support in most cars. Instead, perforate it with small diameter
holes. Some automobiles have solid metal between the trunk and the back of the rear seat which
provides adequate isolation. With other seats, especially the fold down type, another piece of

Answer 3

does not need an enclosure

Answer 4

them must be some weak subs

Answer 5

DOES NOT NEED AN ENCLOSURE

Answer 6

that means that it does not need an encloser... hope this helps
