Post Subject:
can u make a sub box for a car out of sheet metal?
or does a box just have to be wood because the wood conveys the sound
better

1/4 inch steel or aluminum would work. Will need some bracing and damping
like all boxes.

You can make a sub box out of virtually any material as long as it meets
certain criteria. First, it must be airtight obviously. And second, it
MUST NOT flex or resonate. Sheet metal would certainly not be my first
choice for exactly that reason (like a bell, metal has a tendancy to
resonate). Think about it, if the walls of your subwoofer are flexing or
resonating in any way, this flexing requires energy that is wasted, energy
that SHOULD be reinforcing the sound energy.
If your sheet metal is thick enough I suppose that would work OK. Actually,
the VERY BEST material for building a subwoofer enclosure would be some type
of stone like marble or granite. This would ensure absolutely no resonance
of the enclosure, ergo no lost energy. However, because of the weight and
the difficulty of working with stone (attaching slabs together, ect.)
virtually no one builds their enclosures out of it except, perhaps, for some
esoteric home audio subwoofers. MDF is probably the most popular material
because it is extremelly rigid, yet easy to work with.
Anyway, that's my $.02,

On a DIY show i saw somebody using SFDF super fine density. i would not
know what it is if I saw it.
There is a website of somebodys home theater where dual horns are under
the floor from cement formed walls.
Marble and granite do ring up out of the range of the woofer. It can become a
problem and needs to be damped in the upper registers.
If you lamanate, you can use all kinds of combinations of materials.
Plexaglass/aluminum is popular.

True. Though I have never used plexiglass it makes excellent enclosures (as
long as the surfaces are curved for rigidity) as they are light (much
lighter than MDF) and VERY rigid (hence no flexing or resonating).
A common misconception is that different materials affect the sound quality
of the bass. This is not true. The point I was really tring to make was
that if the sound quality IS different between materials (given the same
internal airspace, and same size port if bass-reflex type), then there is a
PROBLEM with the subwoofer enclosure. In other words, MDF (or any type of
wood) enclosures don't "sound" any different than fiberglass enclosures,
stone enclosures, metal enclosures, ect. as long as they meet the two basic
requirements I mentioned before A) must be airtight and B) must not resonate
or flex.

How about saving your $.02 and repaying all those that your ripped off on
Ebay.
Anyway, that's my $.02 to get you started.

Yes, you've mentioned that Nick Tanner character before. He definately
sounds like a scam artist and should be avoided at all costs.
