The Joudas project

Nice. I like the larger holes compared to the MCM variety.

Where did you find the black xo boards? Absolutely stunning color and application by the way!

Those are from Parts Express. I am very happy with them, they were pretty large so easy to work with. https://www.parts-express.com/black-...5-x-7--260-194 -Trevor

The Zaibas subwoofer is also complete. I received and installed the SpeakerPower SP1-700 today. The subs are wired in series for a 16 ohm total nominal impedance. This little sub is amazing! I am listening in my home theater room right now and had to make sure I didn’t accidentally have the 18s turned on.

The Diversions are done

Thank you! I hope he is able to enjoy these for years to come. I love sharing these with him.

I spent some time color sanding these today. I also did a quick flow coat of clear and these are done! I will let these cure overnight and then I will build the crossovers on a board and instal the drivers and ports tomorrow.

I keep trying to capture the color on these but it’s hard to do. The paint is mesmerizing. The ocean blue metallic pearl on top of the blue paint give them a real sense of depth. This is the best I could do for now. I will try to get them in the sun tomorrow.



Also, just an update on the other subwoofer, not all ideas work out. The orange color was a bust. It looks like a construction cone. I am going to re-spray these in a color called blood orange:

I wish I has speakers like that as a kid, or teenager! Many of my x-overs have a high part count. I think it's worth it usually.

Ok, I have finalized the crossover for the Diversion. I ended up going with this:





They measure and sound fantastic!



2nd order distortion at the crossover point at about 95dB output is 0.2%, 3rd order is 0.04%. Distortion reaches a peak of 0.7% 2nd order at 2.2kHz.



I wish I could have gotten by with a less complicated crossover as these are on the pricey side. But I can't argue with results. I will be color sanding and polishing the cabinets today and then I will build the final crossover, put it in the cabinet and this is a wrap. -Trevor

Interesting choice of port location but makes sense due to the greater height of the cabinet than its depth.

Thanks for the clarification.

3 Dedicated areas - Oh, yes! I need one are just for the router right now - the bench routing dust is well controlled with a central system but even with the dust collection on the circle router the very fine dust manages to get into everything - need a paint/routing booth. What are the two holes in the tops of cabinets and are those tuned ports on the backs/bottoms of the bases?

The two holes on the top are for the ports, 2 x 3” ports. I can’t remember the length, like 12” or so. The hole you see on the bottom is a cutout for the speakon connector. The speaker wire routes through the stand into the bottom of the box.

Wow!

That's . . .well . . . Bluer than, BLUE!

What are you doing for over spray/vapor control while spray painting?

Those look great.

Thank you!

The worst part of the overspray used to be with primer, that stuff sticks to everything. I switched to a high efficiency cap on my primer gun and that has reduced overspray by about 90%. When I spray in the garage I put paper over most of my tools and I turn on the heater and open the door. After I spray I leave the garage door open for a few minutes and then I close it about 3/4 of the way. That seems to control things pretty well. One day I will build a dedicated shop with three areas: woodworking, metalworking, and a paint booth. Until then I have to deal with always getting a bunch of junk in my clear coats.

Another long day in the coal mine and The Diversions are painted. -Trevor

[trevordj]

I have been working on painting for the last several days. The Diversion and it’s compliment, One of The Zaibas subwoofers are getting coated with House of Kolor Lapis Blue augmented with Ocean Blue kosmic sparks pearl The other Zaibas sub is going to get coated in House of Kolor Eclipse Orange with Gold Rush Kosmic Sparks Pearl or HOK Great Pumpkin. After I catch up I am going to design and build some small bookshelf speakers for my younger son that will accompany the subwoofer. I have quite a few raw drivers on hand so I should be able to come up with something. Or Paint and clear are on one of the subs. It will need cut and polished, possibly a flow coat of clear, we will see how it goes. -Trevor
