Anyone see any problem with these Subwoofers? 8inch.. Avalanche. I have been looking to make a DIRT CHEAP computer sound system.... they cost $14AU from Strathfield... and go for about $40AU on ebay... 😀 lol RRP is $29
At that price why not buy 2 and try them out.. lol 😀
Not too bad looking... lol I think I'l buy some when I get some money... 🙁 😛
An externally hosted image should be here but it was not working when we last tested it.

who knows !!!!
but for $14 as a sub, worth a try.
just don't believe the 250w rating, could mean anything !!!!

Re: who knows !!!!
Yep, just need some money... and time to set up and measure the drivers parameters 🙂 how do you work out the cone area? lol yeah, its like 250watts max.. lol I'd give it about 50watts rms.. 🙂

lol..
yep
that
sounds
about
right
...
isn;t
it
time
for
bed?
if
my
spacebar
didn't
work,
would
you
mind
me
typing
like
this
all
the
time
as
I
can't
afford
a
new
keyboard?

cone area = pi * r^2 (a good enough approximation) - esp. when the cone is as shallow as the avalanche.
I reckon you can't go wrong for 8"....
Put it this way - the more practice one has on cheaper drivers, the better the result when it comes time for the more expensive ones.
BTW - measure diameter from outer edge of surround on one side to inner edge of surround on the other side (in other words, include 1/2 the surround roll on both sides in the diameter measurement).
Dave.
Dave gave the usual way to measure the cone diameter. Another way is just to assume, for drivers larger than 8", the cone diameter as being 1.5" less than the outside of the frame. So a 10" woofer has a cone diameter of 8.5" for example.
Cone area is not so important a spec to get right on the money. Perfectly useful ballpark figures are:
8" = 32 sq in
10"= 56 sq in
12"= 84 sq in
15"= 132 sq in
Also: Two 6.5" woofers approx equal the cone area of a 10"
Two 10" woofer equal approx the cone area of a 15"
