    A nice coat of flat or semi gloss black rattlecan paint would do wonders here. Perhaps some fill for those cracks in the veneer.

I use a piece of tape on the router bearing to tighten up the veneer cut out.

    The oversize cutout, if you go the way, can also be filled with peel and stick felt cut into strips with a rotary cutter.
    Next time, I will cut the hole with the veneer already applied. Did this with another speakers and was so much easier! You have to be careful not to mess with the veneer, but that's OK.

    Thanks all for your help.

    I will, eventually, get the Whiteside bit and/or file the Freud I have.

    The speaker grills are a nice solution, and I tihnk I will consider it.

    For now, I leave you a picture for you:

    I do own this bit, but it is still to big for the work.
    Take a grinder to the bit and make the follower on the bottom shorter, then it should be about the equivalent of Bill's bit

    The tip is about 1/8" long, so it will work with a recess depth as shallow as just over 1/8". IMO if you're not recessing by at least that much it's not worth doing anyway.

    I have to admit to being lazy - I just used a speaker grille when I made a similar mistake....

    Tom, thanks for your suggestion, but It's really a ton of work. The speakers are finished, so unless I can fix them without disassembling, then OK. I will upload a picture for you to check.

    Here it is: https://www.parts-express.com/parts-...-roll--260-542
    they also have 3/8" thick as well.

    overlap the seam a bit and cut with razor. You won't see the seam.

    post pics please before and after if you wouldn't mind. I'd love to see how it comes out. I screw up all the time, don't feel bad. ):

    Bills bit is what I use for your situation. FYI, a small trim router is great for this bit as it is much more fragile than normal bits. Harbor Freight has a good trim router for 30 something bucks that works fine.

    To fix your problem. Screw a board behind the baffle. Then attach another board in the middle section at the same thickness as the front of baffle. Find center of driver opening by marking hole to hole. Re router a larger opening by 1/8", fill the gap with PEs foam speaker gasket tape. I'll get you a link...
