HDF is by definition more dense and thus heavier than MDF. If you want light and strong, you want birch plywood.

When I got my MDF during the winter, around February, it was $6.88 for a sheet measuring 48" x 24" x .75"

I don't remember the pricing on the larger sheets.

ONE: Get Holly Hill, not Georgia Pacific MDF. Holly Hill is brown in color and is much better stuff.

TWO: Go to a distributor to get the sheets. You can buy "damaged" pieces that barely have a scratch on them for $5.00 each. That was 5/8, 3/4 or 1" sheets. If you know someone there, they take a hammer to the corner of a perfect piece, put a slight ding in it and it's $5.00 also. That's a technique called networking.

That and the 1.5" and thicker crap does not do well with a router for rounding. They "felt up" instead of stay solid. The thicker pieces don't have near the amount of glue. The Holly Hill HDF is $5.00 more per sheet than the MDF, but in comparison....their MDF IS HDF of another company's.

Note what Helotaxi said: If you want light and strong, you want birch plywood. This is what pro speaker cabinet manufacturers use. They must use it for a reason.

Check out http://www.oapaudio.com, they make the systems for iMAX theatres and many more.

Good BB ply will cost you around 60 bucks a sheet.

I just bought 2 1/2" and 1 3/4" sheets also. //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif

I know in Europe, they have some Birch that is retarded thick. I'm sure that 200 different competitors use it, but the one I know of is the SPL Dynamics Volvo. The pieces inside the box were like 2.5" thick of some Birch Plywood sandwiched by kevlar layers, burgundy in color.

How much is 1/2" Birch?

Was hoping to build a new box for my l7's from 1/2" birch, with a 1" speaker baffle.......

Is that also $60?
