Hello,
I am building the Philharmonic BMR speakers and thought id start a post about my progress. Before purchasing the kit i tried to find a build guide/progress report on the speakers but didn't find anything. Maybe someone will find it useful down the line.
Materials:
Speaker Kit - Meniscus
Birch Plywood
Cardas binding post / Blackhole Damping / Soundcoat damping - Sonic Craft
Tool Purchase:
Jasper Hole jig - Amazon
(so i bought this knowing it did not fit my router with plans to purchase a compatible one, well come to find out its compatibility list is less than accurate, be aware)
So far i have cut all the wood pieces, the next step will be to cut out all the speaker holes, brace hole and the recess for the binding post plate.
I have the crossovers mounted and twisted on the mdf boards included in the kit, after reading through some posts here ive decided i need to find a better way to fasten the components to the mdf. A user recommended E3000, I'm going to give this a try. Soldering coming soon
I will update some more pictures of the cabinet cuts ive made so far next day im in the shop.

The BMR baffle cutouts have been a bit more of a hurdle than expected. I thought maybe i would freehand them but after a few tries on some test wood, that's not going to happen ha. i considered using a flush cut bit on my router to trace a template around the BMR but i think i can do better.
I have drawn up the Baffle cutouts and plan to find a local cnc shop to cut these templates for me
Note: A 1/2 inch diameter router bit is to large to fit into the detail on the BMR, need a 3/8 or smaller bit

Sure!

That is correct, 3/4 inch high density plastic templates. Thank you! Im happy with the progress so far.
Thanks!
Finished up the baffles tonight, need to fill that knot in the woofer step, just my luck ha!
To anyone who builds these using router bits for the fillet and recess on the baffle, make sure the second cut has enough room for the bits bearing to rest on.

Some completely unsolicited advice: Fill that knot in the woofer recess with some epoxy to stabilize it over the long-term. Epoxy doesn't just fill the void, it will resist the knot's need to stretch over time and create leaks in your baffle.
How do you plan to finish it, anyways?

Thats good advice. I was planning on filling the knot with a wood glue/sawdust paste but your right, epoxy sounds like a better solution.
I will be clearcoating the raw wood with AFM Acrylacq.

Your speakers came out really nice, thanks for sharing the details of the build! I am researching this design for my next project, and I was looking for some drawings of the baffle cutouts to use on a cnc machine I have access to at work. Would you be able to post larger versions of your baffle drawings with recesses if you have them? That would be greatly appreciated!
