Impressive, indeed! What amps and processor will you be driving them with? Thank you! I have two SpeakerPower sp2-8000 amplifiers (the ones I modified earlier in this thread to add a remote turn on circuit). Processing will be a minidsp and the XMC-2

Things are moving along nicely today, with the repetitive lifting of these boxes over the last few days I woke up with my back being an absolute mess today. Because of that I am moving slow. When I tried to do a makeshift diy circle cutting jig I messed up the cutout a bit. I got the jasper drilled out to fit the festool router and slopped a bunch of body filler in the void and re cut it. Otherwise I put chamfer on the baffle for decoration I hoisted these boxes under my drill press and got the cutouts for the speakon connectors taken care of. The outside of the boxes are done, this afternoon I am going to glue the brace blocks in place and start sealing the grain for paint.

I lied, the outside of the boxes isn’t done. I ran a pencil tip bit along the joints and will fill them with joint compound to hide the joints under the paint. I glued the brace blocks in place after re-cutting some of them. I started with some joint compound, I will sand and re-apply tomorrow followed by some polyester resin to seal the wood.

A lie is: "To present false information with the intention of deceiving". Maybe you misspoke, or misstated your intentions, you might have altered your course, modified your method, revised upon reflection, modulated the mode, the operation may have been obfuscated so you had to transmute the effort, adapt your previous determination, changed your mind, but you didn't lie.

I got the updated, simplified designs for the LCRs and the surrounds. I put the order in for the wood and will likely pick it up tomorrow. I have never used mud for filling gaps on a project like this before. I like how it stands but with these deeps grooves it takes a long time to dry. I will probably go back to body filler. I just wanted to see if this would be easier. I'm assuming drywall mud? Wouldn't that for sure crack quickly? I like the body filler idea, but wouldn't something like fiberglass resin be the best?

Polyester primer (which is really the same as fiberglass resin) will be used over the filler in either case. Drywall mud or plaster of Paris is actually excellent for being covered with resin because it is pretty porous once it dries so the resin penetrates it and bonds well. All that being said, I have just seen this is a common method for finishing wood boxes but I have never used it before. I definitely won’t do it again. The ease of sanding this stuff is far outweighed by the amount of time it takes to dry. There is also the question still of whether it will crack or not under the polyester resin. Time will tell but like you I am skeptical. I’ll stick with body filler.

It was recommended on another forum that I add some additional bracing along the back panel of the subwoofer. Sounds relatively simple and straight forward. Here is the plan: The trick will be getting the braces in since the box is already complete. This doesn’t have to be anything fancy so I can rework it if necessary.

Progress continues slow and steady. Life has taken some unexpected turns in the last week so I am dealing with that. I had put in my notice to quit my job 4 months ago as I was hired at a new job with more money and fewer hours. It is standard in my field to give three months notice to voluntarily quit. Well, I was terminated from my old job early when everything started to tank from the virus, no worries I just looked at it as a month long vacation. Well, my new job told me two days before I was set to start that they were terminating my contract. Now I am without a job for the first time in my life. I found out about that a week ago so I have been scrambling to figure out what to do since. I am going to be starting my own business instead so all my energy has gone to that. Things are happening quickly and I think going this route will be a better move for me long term anyway. I got some garage time today. I am carefully cutting dados for the LCRs on the router table. I also had to assemble a miter station. I wanted a proper stop block so I cut. It all the baffles at an identical 38.5”. Some of the dados have to have a blind stop. I used the router table for these, it wasn’t as bad as I thought. I had to take yet another detour, I am building a vacuum for glue ups and veneers. I designed the case with fusion 360 and am cutting it out on the CNC. It is a project EVS vacuum. I just have to cut the front and rear panels. I’ll be using the CNC to do the cut outs for the tweeters. I’ll use the vacuum to glue up the baffles. Onward and upward.

Sorry you are going through such turmoil. Hope things work out for you quickly enough.
My company shut down, so I was "furloughed" in March, signed up for unemployment, then a few weeks later learned that I was being reinstated (so canceled the UI) per the SBA PPP, but it still hasn't funded so I haven't been paid in six weeks - but it's coming supposedly, hopefully this coming week. I know I'm very fortunate. I know too many who are not. It's a small gesture, but I frequent local business more than usual to help even though my resources have been stymied.
I wish only good tidings.

I wish only good tidings. Oh man, it is such a rough and strange time. I am glad you are hanging in there. Many could not go 6 weeks without a paycheck and still have any money. Like you, I consider myself fortunate. I luckily have enough savings to last 1.5 years, longer when I win a lawsuit against my employer who broke my employment contract. I finished milling out the vacuum cabinet. I’ll glue the base and screw the sides and top (for serviceability) and hopefully I will use this to laminate the baffles tomorrow.

Sometimes bad things turn into good things. Kudos for making lemonade out of lemons and best wishes for success with your new company! Start ups can be fun, but intensive and I hope you still have time to enjoy hobbies and other activities that feed your soul!

Some more incremental progress. Most of my weekdays are dedicated to getting my business up and running right now but I am able to sneak some time in here and there. I got several of the holes cut in the braces and made a cutout so the woofer will clear. One of these days I will get back to prepping the subwoofers for paint. I want to get the front stage and surround speaker cabinets assembled first so I can tackle measurements for the crossovers.

The rest of the holes are cut, the relief for the speaker is cut and the cutout for the tweeter is done. I thought I was going to have to do that with the cnc but it was easier to cut a template on the router table and transfer that over. Everything is nice and square, I will let the clamps sit overnight and glue up the other two tomorrow.

Man, that's a lot of holes! Very nice work, as always!
