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,
MOSFET
