where to buy 1" MDF?

hdf = bad sound i think.. same problems that plywood has.. correct me if i'm wrong i have sheets and sheets of HDF at my shop that have been there for a long *** time.
maybe so, I've never built an enclosure with it.

MDF does FINE, especially if you 'paint' the inside with wood glue. Hard @ss sh!t then.

 
HDF is like MDF, but better //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
HDF = high density particleboard.
*High Density Fiberboard

1" is a few bucks more than .75" here from a lumberyard..
same here, its about 28 for .75 and 31 for 1 inch, i see no need for it, like jmac said properly braced 3/4 is better than 1 inch unbraced, maybe for a 7 cube box use 1 inch and brace that too,

the problem with gluing 2 sheets together with wood glue is it has to have alot of pressure on the 2 boards when gluing them together, well it doesnt absolutly need it, but it is much better with a bunch of pressure, i would just lay 2 sheets on top of each other, put 4 clamps on each corner, then cut the peices you need, then after that glue each peice together and apply allot of pressure to the 2, we use a 350 psi press at work to do it, at home i have 2, .75 inch sheets of steel, around 20 inches by 20 inches, get a couple ppl to lay it on top of what i need glued together and still add a couple clamps
