I work in boats all the time, so I always have some lying around, never noticed about the price. Guess you are right.

One late night, well a six years old go to bed quite early, but anyway I did steal back some foam board.

And built a Mini BiB's..
Hang on, is fast but not as fast, as the glue dries in 5 minutes ..

First, measure twice

3 minutes later, cutting

All the pieces took about 10 minutes to cut

Starting to glue

Made one or two small mistakes along the way, that made it took a little longer than necessary

Among other things, that the speaker did not fit, so I had to build a small box behind the magnet. Wait that was not really my fault i guess.

Damping in place

Tried not to repeat the mistake they made in Italy when they built the Leaning Tower of Pisa, trying to cut the bottom straight.

Upside down, and five minutes drying time, what a waste of time ...

Playing time..

How should I describe the sound then?
WOW, I'm stuck, feel a new addiction coming

Of course they do not rattle any windows, but there are enough bass so that's really fun to listen to Vicious Delicious by Infected Mushroom.
But they need not be ashamed when they play Ohio by Over The Rhine or Joy to my soul by Oslo Gospel Choir.

Oh sorry picture of speakers used..

The NS3 is running full range, the Vifa tweeters are not connected.

Already having some ides for the next build. Only have to find a store that sells foam board cheap.

Nicely done. What is the thickness in mm of the foam. It looks thicker than what we have in in our US office stores.

Is the material really foam core? It looks like expanded bead (popcorn) to me.

Mag,
Nicely done! Finally someone with a big foam project. I bet it sounds great.
Love it. I see the bug has bitten you now. Isn't it great to not have any sawdust and you built it in your living room in what? An hour?!

Thanks, thickness is on front and back 10mm (3/8 inch) and sides in 5mm (3/16) in stores you can also buy 3mm (1/8).
But they are quite expensive, to bad.

Actually I haven't any clue, it is sold as foam core board, in the store I bought it in.
I will try to take a picture of it. But it looks like the pictures on Google when I search for it.
It is /thick paper/ foam /thin paper / foam/ thick paper.

\\M,

Did you buy your material from a "Dollar Store" or from an outlet like Home Depot? It looks quite useful for bigger projects. I haven't seen anything with compound construction here.
