Philharmonic BMR Speaker Kit - A Few Build Notes

William,
I've made templets for the BMR, let me know if you need one.
I'll copy mine and send it to you.
At least the Tectonic tabs are 1/2" so a $10, 1/2", top bearing flush bit will work nicely.
[they make 3/8" top bearing flush, but they don't look like they will last that long]

How to make odd speaker shapes - old school? I bolted a metal frame speaker face down and copied with a bottom bit router.
Step two, use a router-collar to go back to the finished size you need. I found it that you can fabricate (custom) bottom router plates pretty fast; probably what they did back in the day, before you could just buy them (collar kits).

Not sure this ploy would on a plastic BMR
I don't have a 3D printer, but that might work also.

ODougbo,

That is very generous of you. Thanks very much. Let me know what you need from me, and I will be happy to reimburse you for any cost, materials, work, and shipping.

Nice build! Doesn't look like your first time cutting wood haha. I am in the process of building my kit, your notes were helpful. Here is a picture of the crossovers if anyone is curious, was trying to find one to compare them to mine but no luck on the internet. Before i start soldering maybe someone could tell me if they notice any critical errors lol.

(if your wondering what the holes in the mdf are about, i was going to use the solderless connectors then decided against it.
