Weekend project: pair of Atmos Volt-8 boxes for TM in the family room, they will be under the beam.
I’ve used neo magnets for grille attach before, this is first time I wised up and drilled from backside, saves some front finishing like I’ve done on other speaker projects. Live and learn.
Tell me you’ve never had this experience before .. you think the wood filler / epoxy is sanded nice and flat, then on one corner ... ugh
The magnet barely shows, but you can see it and can’t live with it like that ...
Drill on backside ... with drill press won’t go thru front .
Test depth of hole
I modified the flat face drill , ground the original guide tip 50% shorter and put angle back on it
Worked fine on first 6, 7th I hit slightly too hard with 1/4 punch pushing the neo magnet down to bottom and slightly split the mdf baffle.
I had the baffle fully supported on backside when hitting the neo magnet down, just gave it a little too much umph.
It will be covered with veneer so hide the mistake .
These were put 3/4” from both edge, in retrospect I’d put them at 1 1/4” from both edges for future builds.
The volt-8 will replace the 1996 bipoles hanging on that beam .
