    Im building a cab with plans from bfm. And the plans dont say how big to cut the holes for the speakers. I was going to guess and say 9.5 inches but I was scared that I was wrong. Im still in the planning stages. I have the wood cut to size and Im about ready to start.

    Are you using an Eminence driver? Their spec sheets give copious information to guide you with mounting.

    I'm with Sanny, here. I'd say somewhere around 10".

    I just turned the speaker over and drew round it to get the outer size, then cut about 1/4" inside that line to get the right size. I was a bit conservative, so I then just sanded it out to make a REALLY snug fit.

    No idea what size it actually was - I suspect there's some variation between brands. The one thing better than measuring twice/cutting once is to size to fit. Whatever size my driver was, the hole was the right size.

    Did your speakers come in a cardboard package?? (If they're new)

    Usually every packaging box I've seen a driver come in , sits on a piece of folded cardboard, that has a hole it sits in, try using that?
    Otherwise, do tell which brand of speaker you are using, not every manufacturer has EXACTLY the same suggested size.

    IITP. It's in the plans, the part where it tells you Cut the driver holes to the diameter specified for your drivers on their data sheets.
    BTW, if you do not have the drivers in hand you should not be cutting any holes.
    You should be asking this question, and any others with respect to the cab construction, at

    The specs are on the Eminence site, but, as Bill says, wait to make the cutout.

    You also need to have the driver on hand to mark and drill the mounting holes.

    So move on to another part of the cabinet if you can while waiting.
  14. I published this on the BFM site about cutting smaller diamter speaker holes in Bill's rear-mounted designs:

    One of the BFM forum members constructed this excellent drawing. A picture is worth all the above words.

    Link to Drawing

    The drawing also shows cutting the baffle hole with a 22-degree router bit. This gives even more meat for a T-nut mounting without cone slap.
