    MDF vs Plywood...

    Just read this, "The Loud Speaker Cookbook actually states marine grade plywood or sheet pvc is a superior material to mdf for sub enclosure construction. Both the plywood and sheet pvc would flex with the sub but remain air tight."
    True or not?

    IIRC any type of box flex is no good.

    If flex was good, then why are SPL cars loaded with sound deadner and sometimes filled with concrete?

    yes...flexing is bad...

    numerous people have gained on the tl through bracing their box

    Good hardwood ply is lighter and more rigid then MDF.. meaning it's better..

    Of course it's also a lot more expensive...

    Re: MDF vs Plywood...

    Personally, with my experience...I think plywood if far superior to MDF. It's lighter, NOT compressed, and flexes far less than MDF.

    Think about it, MDF is compressed and glued dust.

    Re: MDF vs Plywood...

    I once built a plywood box for fun because I had extra plywood laying around.

    Sounded fine.

    True or not?

    Also consider most applications that that book considers are low power low x-max.

    I prefer plywood as it's lighter and much easeir on tools.

    MDF flexes plenty and really most conventional boxbuilding materials will. There is no substitute for bracing!

    I know a few serious SPL competitors who would disagree with that statement...
