I think one simple sticky post with how to use packing peanuts to measure the volume of an enclosure would save a lot of posts.

I was just thinking about that the other day.  Proper use of peanuts to measure volume space.  I would also like information on it.

It really isn't that difficult. If you fill a container that is 1" x 1" x 1" with packing peanuts, you get 1 ft3 of volume. Moving this amount of packing peanuts into another container that is of a different shape, but the peanuts still fit will yeild the same cubic volume.

Othewise, if you have an oddly shaped enclosure (fiberglass, let's say), fill it with peanuts the same way. Then you need to take those peanuts out and put it into a cardboard box that has easy dimensions to measure, and find the volume the peanuts consume in that box. That is the interior volume of your 'glass enclosure.

hey dxav don't you mean 1' x 1' x 1' (one foot by one foot by one foot)?  not 1" (one inch).  But yeah that's probably the most comon and easy.

Hahaha, yeah, good call, Boxmaker. Thanks!
I usually don't denote measurements in that style -- now you know why!

lol had to say something b/c i could see some newbie wondering why he is only able to measure one peanut in his 1" x 1" x 1" measuring box at a time.  and wondering why his box sounds so crappy.  You never know about people today

I can easily get 4 peanuts into a 1" x 1" 1". Can't you?!

Seriously, though. Did my explaination work for you s7726 and Melted Fabric?

I noticed it is a stick now, so it probably should be ok.

ok  say you have measured in a cardboard box . How do you put that measurement into the (fiberglass enclosure ) before you do the frame work and put the resin on the jersey material or fleece? do you just guesstamate? I would hate to build a box and then go cut the holes for the speakers and fill it with my peanuts and have alot left over..or is there  a way to compensate for the lost peanuts? I know I probably sound stupid and the answers probably in front of me,but , oh wells.

I have heard the general concensus is to guess BIG, then you can put in some extra random space taking material if it's too much space.

Well, after the material is stretched over the ring and back, I just don't seal one small hole, and fill the peanuts thru that. Then I take them out, put them in the box, and measure. Then if the ft3 is good, I seal the fiberglass enclosure up completely. I usually use hot glue, holds well, and is not permanent. If you are stretching over MDF, then use a staple gun for the final streching.
