    Hi Michael,
    There is a guy not far from me who's been making concrete speakers using Jordan drivers for many years. It might be worth contacting him for advice/tips. I've met him once and he seems very approachable.

    Mine were Tannoy M20. A 2-way with an 8" bass. I built the cabinets with the original internal volume and grew externally.

    May or may not suit the size of hole you're after, but you can hire a core-drilling setup from a tool hire shop. The kind of thing you would use to make a hole in a wall for boiler flues, bog pipes etc

    I used to do diamond coring way back. Plenty water and preferably a rig etc needed for big holes

    The Link is to a material I was once keen to Laminate and trial on a OB Speaker.
    The link covers a few versions of the material, I believe the material I become familiar with
    is the Portland Version.
    These materials cut with a Jigsaw with relative ease, as well as can be found in a thickness up to 12mm.
    Two or Three sheets can be laminated, to make a Wall thickness of choice.
    With a little though in the design of a cabinet, a conventional version of Speaker Enclosure Joinery can be mimiced.
    My OB Baffle was going to have a Three Ply Lamination, with Ply Layer Two being different material, so possibly a CLD Type of configuration.
    I till have 4 x 15 Bass Drive Units for the project, so maybe one day, I will get there.
    My ESL 57's are yet to be championed, by a younger contender.

    Thanks for the link to cement board. There are several different types it would seem. One is bendable I wonder about their effectiveness when used for a speaker cabinet. Definitely easier to work with than concrete.
