me either

i just go and look what they have, and buy what is cheapest.

no need for that very expensive shit that is supposed to be void free, and no knots on the surface that have been filled with filler, who cares? unless its being stained and it has to have a flawless finish, F it, get the cheapest 3/4" birch u can get. especially if its double layered or braced, a few voids (small) here and there wont matter...

i think people make shit up, becuase the pricetag is cheap they assume its bad.

thats not true.

i like it better than MDF, ill use the cheapest birch over mdf, becuase mdf sucks.

but yea in a month or 2 if ur at HD on DM and i275, check if they have that 28 dollar 3/4" birch, its what i used on the first wall. the 2nd wall i had to use the cheapest i could find which was lowes for like 40 a sheet //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

i saw some birch that was treated with something that made it shiny on the surface, and i stained that once...........it left such a nice shine on it.....i havent seen it since though

If its one car going with a TON of wood, then 30lbs a sheet adds up. I got 20 full sheets of 3/4" in my van, so thats 600lbs difference. If you're only using like 4-5 sheets for a build in a single car, just go with regular MDF.

Or just use regular MDF anyway like me if you're too cheap to buy Trupan, Birch, or Ultralite. //content.invisioncic.com/y282845/emoticons/mad.gif.c18f003ab0ef8a0d9c27ca78d77a6392.gif

the guy @ HD told me the main difference in the different kinds of birch are the cheaper ones have more voids and if you look on the surface, there is filler to fill the knots/small holes

the shit thats like 70+ a sheet has no filler and voids.

dont need voidless/filler-less wood for a speaker box

IMO

well i only have 3 sheets (not complete, but i bought 3 sheets) of 3/4" but had i went with MDF, even though only 3 sheets, thats alot of un needed weight for my car, when i spent a little more money (double actually of mdf) and saved at least 50% weight or more. my box is only about 140lbs without the subs

edit, i dont even like ultra light or trupan. any box i build for anyone i try to convince them to get birch. if not, oh well, i still get monies from the box build.
