  1. Apart from being a time honoured tradition, MDF is easy to paint, laminate or vinyl wrap.
    Also, it keeps the cost of the cabinet build down.

    Who here still prefers the sound of paper based materials for driver cones compared to today’s plastics (TPX, polypropylene, etc.) metals (aluminium, titanium, beryllium) or kevlar & carbon fiber?

  2. Early 80s, I remember seeing (sadly not hearing) a LARGE pair of custom built consigned speakers with (according to the salesman) an outer box, an inch & a half of sand in the bottom, an inner box 1.5 inches smaller, sand filled between. Unsure how the drivers were set up as the grilles were on. Apparently they were modeled after the Pioneer HPM-150 – with 15″ woofers. I remember the salesman commenting that nobody could ever possibly steal them….
    I remember I gave a double knuckle-rap to the side of one enclosures; it was akin to the sound one would hear if a medium sized humming bird flew into the hoover dam at a low rate of speed.
    Minus the squeak.
    There’s a tweeter joke in there somewhere…
