Making and Installing the Crossovers - OB Speakers Finale

I finally have this pair of speakers done and I'm enjoying the heck out of them every night in my society deprivation chamber (aka, listening room).
Sanding to 220 grit, then wiped on three coats of a tung oil blend, letting each coat dry 24 hours. Then top coated that with two sprayed on coats of satin water based poly to give them real protection and get the gloss level I want.
While all that was happening I assembled the crossovers. The circuit board I used was a thin piece of solid cherry and I connected the components point to point. Drawing the schematic on the first one really helped, then I tested that before doing the second one.
Fishing the wires through went okay, but if I were to do it over again, I'd spend a bit more time making sure the passage through the base was smoother. Or just put the wires in while assembling the base - that would be easier.
How do they sound? Great! But keep in mind that these were designed and made for a very specific purpose, and that's to replace the first reflection off the side walls in my listening room. And for that, these are perfect. If you don't know what I'm talking about, check out the first video in this series where i describe this reflection replacement principle. Click the link below.
This is part 7 (the finale) in my series on designing making a pair of open baffle 2-way speakers to use as "surround" speakers in my listening room.

You do beautiful work John…
Thank you…

[specialks]

John, you are an amazing man of many talents! Nicely done sir!

[robertdiffin]

Beautiful speakers. I’ll have to go back and watch your full series. Inspiring work.

It's raining here while watching this video. For a few seconds I thought my roof was leaking, then I paused the video. Yup, my roof is leaking. Squirrels love making a hole in my roof and living in the attic.
Speakers turned out really nice and really cool to see you wire that crossover.

[dariuszrzeczkowski]

On OB most people expose the crossover and you hid it beautifully in the chamber. Great job!!😉

[gordiefrench]

Hello there John
Such beautiful wood work and a cool design very different look

[macedindu]

The rain sound is some relaxing ASMR stuff! xD

[kalvinmiller]

Nice craftsmanship well done thanks for sharing

[josvanoorschot]

Looks great, but cannot judge the sound. Have seen your woodworking before and you are one of the best. I would never built an open baffle speaker. The rear end of the speaker is not designed to be open. I’m more a fan of the Troels Graveson designed speakers. Recently built a speaker from soundblabs with good result. Next one will be from Troels one day I hope.

love the woodwork. wish i could do that

[Keasbeysknight]

version 2 could have the channels for the wires recessed with the CNC, see how light of passes you can make! great video awesome series.

I need a Society Deprivation Chamber !! 😂

When you say “a rung oil blend” exactly what is the blend. It looks really nice going on the wood.

[luckyrashes]

Did the addition of the capacitor to the woofer add an order to the crossover? I ended up removing an order from a crossover but you can imagine it's not as clean a procedure when you started with it 😅

[johncnorris]

I think those metal plates may have an unexpected effect on the sound of the speakers. It will likely shield any outside electronic noise from any nearby devices from being added to the source signal. Good design!

[marcusjones]

Absolutely awesome. I've been waiting to see the outcome. One question, how did you determine the crossover component variables?

[dennismiller]

Great Art, how do they sound once integrated?

[mrmano]

Can you build custom Crossovers and do you have software for speakers thank you

[mussoaj]

The speakers turned out great! I'm a new woodworker - why did you apply the tung oil in three thin applications, rather than flooding it on? Thanks for all the great inspiration.

[petertimp]

Oh, and it sounds like you have a waterfall in your workshop 😊
