read my comment please!

[@freedomwriter2901]

I hope you read my Comment! I've been following you way back and realy LOVED your videos and ideas. You were one of the reasons i studied audio engineering. I recently finished my diploma 2 month ago. I forgot your name of your channel. So i searched and finally found you again. Now i'm looking forward to also build my own speaks. Thanks for the inspiration! Much love from germany! 💯❤🙏

[@SoundBlab]

That is really good to hear. The reason for sharing these projects is firstly to inspire, so job done! Thanks for the support and enjoy the process of designing and building your own speakers. It is very rewarding when it works out well.

[@nunocampos1805]

Very cool. These would look amazing in a Home Theater and very stealthy. It got me thinking about a wall mount for the speakers in the vein of yours, but in a kind of a shark fin below to hold them on the wall. You could still swivel them and point them directly at the main user for an amazingly accurate sound immersion.

[@SoundBlab]

Thanks. yes, I think you could find various ways of mounting these using some kind of 3D printed design.

[@jeffbaker8808]

Super cool looking and I bet real-life sound is really good! Can't help but think of the Magic 8-ball, popular since the 1940s when the questions to life, (or speaker design), were easy to ask and easy to answer.

[@SoundBlab]

Thanks

我使用PLA塑料做倒相音箱时，外壳有很明显的共振，实心3mm厚也有很强的声染色。密闭箱确实要好很多

Yo. I built a Bass Ball back in mid 96. It had a 10" Orion. Sounded great. Sold it. I've made several more. I even tried to sell one to a sports star. anywho. Now that I have a multi axis 3D printer. Crazy how stadiums been using them for ever. I got the idea from the speakers that where in our gym in the ceiling at highschool.

[@Padde298]

Excellent build as always. However I would like to know why you are using dampening material in the enclosure which also holds a passive driver...? It seems to me that you are tryin using two methods to obtain the same result: the driver "sees" a bigger cabinet. Generally you would chose either one of the two. Not both

[@SoundBlab]

The PR is no more than just another version of a port. The difference we do not have to deal with port noise. Sure we can end up with a slightly smaller enclosure in the PR, but a larger enclosure within the driver's limits will always be better for bass response, so any way we can make that enclosure 'appear' larger will be beneficial. So, not really a matter of choice. You work with everything you have to get the max from a design. Thanks for a great question!

[@subbab4]

Really nice-looking speakers and they sound very similar to the Marley speakers that I have connected to my computer. Just a note...could you please refrain from spray painting while I'm eating dinner as I think I can taste the paint.

[@SoundBlab]

LOL 😅

[@litoboy5]

Great job and great performance

[@SoundBlab]

Thanks

[@Leo-tf7gu]

Would be interested in a spherical 3D printed 8" concentric mains speakers with compression driver and a paper cone woofer for my HT (90hz crossover).

[@puiaturuburu906]

Why didn't you show the movement of the passive radiator. Its gonna look awesome

[@crossoverchef]

very nice enclosure

[@SoundBlab]

Thanks!

[@Projacked1]

Have you ever conscidered hollow panel designs?. I was thinking about filling a hollow structrure with sand. It would be a cheap way to make a really solid cabinet with excellent damping at the same time. A sphere is by far the best shape as well for a cabinet. So, just a tought..... Nice job man.

[@keatoncreates]

there are a few 3d printable design for free on thingyverse that allow you to fill with concrete or sand! Though there have been tests and at 40% infill PLA is actually almost identical acoustically (including ringing and rigidity) to MDF and not far behind Baltic birch given same wall thickness . Ive thought about doing my own tests since with 3d printing infill if you leave the top layer off you can fill with sand like you say and still have some infill

[@Projacked1]

@@keatoncreates I recently build a small speaker (almost a cube, 4" fullrange driver) with very thick quality plywood. I wanted to know how much the difference would be to other materials I tried. So the thickness (20mm) is beyond what you would buy in the store except for high end stuff maybe.It's so stiff you could kill a man with one blow haha The difference in clarity was stunning. I did have quite a trip finding the right damping on the inside, and learned alot from it. Have you ever seen anybody use plywood in sphere designs, CNC? Because if I would prefer anything on a cabinet it's ply.It's perfect, but quite expensive. And I can't built that.

[@SoundBlab]

Thanks. I have not tried this, but would be interested in experimenting with various methods involving 3D printing.

[@Projacked1]

@@SoundBlab I have seen 3D printing for housing purposes. Like a really big printer that does walls and what not. Materials like that should come close?

[@hobikidalbadminton]

does graphite powder stain our hands if we touch it? or did you apply a clear finish on it after applying the powder?

[@SoundBlab]

No, it does not really rub off just by touching it. If you rub it with your fingers yes. No clear coat was applied, think it will dull the shine. It does need a fresh polish though every now and then to retain the shine.

[@flepper231]

Do you include the 3D CAD files with the plans to make some adjustments? I have a pair of Jordan JX92s laying around and they need a larger enclosure and perhaps a port. It would be cool to adopt your design for this.

[@SoundBlab]

The STL files are included.

[@flepper231]

@@SoundBlab I read that, but I'm interested in the CAD files to import the model in for instance: fusion360 (or other).

[@SoundBlab]

I work in Onshape. What type of exported file to you need?

[@A13tech]

wou... nice ! Now the challenge - to replicate Devialet Phantom :P

[@googleyoutubechannel8554]

nice one!

[@SoundBlab]

Thanks!

[@treywilliams8508]

I'll take 5th comment, wonderful build as usual man, love the spherical builds!

[@SoundBlab]

Thanks!

[@MrManningata]

One thing I would like to see your take on is a set of speakers like this with an integrated amplifier, perhaps with a USB-PD power source for ease of use.

[@আবুবকর-ন১ধ]

why you 3D-print, grint, paint etc... if you get for cheap price and good sounding ball speaker from reckhorn.

[@juststuff5216]

First - and that's a neat build!

[@SoundBlab]

Thanks!

[@xaincomods2417]

Nice build, I can't justify the shipping cost though 😕

[@SoundBlab]

They have various shipping options. The less expensive options just takes longer to arrive. But also dependent on where they ship too.

[@carlfranz6805]

Um... And I could be wrong but... Didn't we do this already?

[@tonysmith7702]

This is the subwoofer build.

[@carlfranz6805]

@@tonysmith7702 thanks.

[@adfgyahoocom]

I like the finish! Cool look! How do this lavoce compare to the markaudio driver from you previous project?

[@SoundBlab]

Thanks. Two very differents drivers. The MA has a flatter response all the way up to 20kHz and as a result perhaps sounds smoother overall, and warmer in the midrange, where the Lavoce has a peak to deal with up higher and perhaps sounds more analytical. For a desktop system, a stereo set of the Lavoce works well and as long as you do not drive it to ridiculous levels in this scenario, it sounds controlled. However, I think the Lavoce will perform very well in a column line array with multiples drivers.
