@@florislsd hmm that is probably just the polish? :)

Thanks man. The measurements are 40sec in to the video and the crossover is on a link in the description

It is just an inspirational video to use creativity. Not a tutorial

@@mackemacchiato3238 It actually seems like a joke

@@KarmaByLush good you can have some fun then. If you are easily offended you can just leave. But leaving comments like that it just shows you want to be mean and is an evil person.

Sorry! Can’t read!

My new idea is aircrete to get a lower vibration resonance and lighter than concrete as the sub speaker I did

@@mackemacchiato3238 Could be an option though. Don't forget to insulate it with some liquid rubber/silicone cause you'll have dust inside after some time (and it such water from an air like a pump)

@@sc0or yes, one can mix some coating like polyester and brush it. The concrete sub I have made as u see in the channel does not dust, but aircrete might.

I found a good video about it. ”Building Exceptional speakers using modern techniques”. Check that out :)

@@mackemacchiato3238 Yep. I saw it, thanks. A smart guy and interesting scenarios each time.

I used a special techinique to pour and reinforce the concrete and this is not an instructional video. More inspiring. Since it would be weird if Volvo did videos how to do the EV Polestar car… sort of…

Some business techniques. It is an inspirational video. Not to put myself out if business and show competitors how to do it…. Since it is not patened

The round shape helps remove resonance and the “shell” vibrating. Egg shell principle . Strong but one can still keep it thin. A globe reduced standing waves inside and reduces unwanted noise. Mostly in higher frequencies, so the round shape is for the strength and mostly for design. Easy to furnish and to look at in a home instead of a black cube as the mainstream producers sells :) I also made one out of a hemp basket 🧺, with concrete inside.

Yes it is! You have the specifications in the latest video where I make these but in another colour 👍🏼

It sounds perfect! It is recorded with an iPhone 8 that has a limited microphone. So nothing you say is correct.

@@mackemacchiato3238 Then you should go to the ear doctor

@@bennip.5009 iPhone8 dude

@@bennip.5009 i have had people here listening to them.. you are the one that is wrong and can’t admit that your judgement was totally irrational since you judge something recorded with an old iPhone

@@mackemacchiato3238 I build expensive speakers myself, and my ears are very good, no matter what phone you use, my ears hear it.

Tackar! Ja jag har ett 2-vägs filter 12db filter delat på 3500hz. Jag har gjort dom i flera år och har dom i ett 7.1-Dolby Atmos system å även som dessa med BT-mottagare inbyggt , så ljudmässigt nej. De är bland de bättre jag hört i den storleken. Synd bara jag var tvungen att slipa av öronen av chassit på Kevlar-elementet och att den inte fanns i rund version. Det är nog allt ;)

@@mackemacchiato3238 coolt! Lackeringen ser ju fantastisk ut! Följer din kanal nu!

@@erikhedarp3426 tackar! Det är bara sprayburk med billack, men man höjer upp det med polering efter så går det att spraya till även i en dammig källare 😅

Thanks man! I was just looking for some kind of sphere I could make a mold of and asked around . Because round shapes gets No standing waves inside, so it is very strong and ”dead” and perfect for a Loudspeaker :)

@@mackemacchiato3238 yeah but only needed for tweeters & upper mids as wavelengths at lower freq are way too long to form a standing wave inside a normal enclosure. Thats why most subs are square shaped. & that b&w 800 series has that tweeter enclosure.

@@datdudeinred tweeters doesn’t need any enclosure at all. Only a baffle to spread the sound. A sphere shape is stronger than a rectangular. Hence eggs beeing strong but beeing thin. So, doing a round shape save volume but still stronger = resonance free than a box.

I don’t understand. Sorry🚢🛖

Hello! Maybe it is not shown in the video, but all walls are covered with a 4cm foam dampening:) thank you for watching !

You would believe so , but that is not the case….

Btw a sealed vs a tline which will be better for sub bass & bass? Isn't sealed is still faster & tighter than tline?

@@datdudeinred good point! There is still a resistance in a T-line to get the air out of it making it responsive even in the mid-bass range! Even though as the former commented say about the sofa , the T-line still sounds better and the placement in the room is incredibly crucial.

Hello! I have bought a calibration mic but haven’t had time to det it up, since I got the wrong type of mic and need a pre-amp to it before connecting it to a computer. But the audio is actually amazing! The stereo spread is insane and fills up even a 50sqm room

I would love to but these are more like prototypes and not with industrial molds. Polyester hardens all the time and never stops, so I have noticed a glitch right at the line dividing the 2 halfs. To make it industrial and get it homogenic I should 3D-Scan it and make injection-tool. So it feels bad sending a couple away with a risk that can happen. (Friends have bought some with knowledge of this, so that is how far I have gone with selling these)

You mean like a paper document? I did those on a whim. But they turned out so good, so I will do another pair soon with another look/colour.

I think one needs to have it stiffer and a longer Tube to give the resistance behind the come so it sounds good as a midrange as well, if you thought like in a 2-way system? This speaker is 6,5” and goes really deep. On monacor’s webpage one have the frequency curve on every driver at 1db/1M and this driver looks great even though beeing cheap! :) I wish I had a better mic because they sound so great, beeing so simple after all. The round ones are easier to furnish, but the TL sounds better.

That is true, as long as one gets the correct amount of volume for the designated speaker then it is all good. Doing creative stuff and having something No one else have is nice !

Have to try that ha ha

Niiice! I see your point! Drum’n bass ha ha

Pretty marvelous. Placed in a corner they even gives good low frequencies. So I sold a couple to a company that have them in a lunchroom in the upper ceiling corners and they asked where the Subwoofer was. The tweeter is one of the expensive ones in Monacor’s catalogue and gives amazing details without beeing too sharp for listening even very loud!

Thanks man you took time to watch and write! I hope I have time this weekend to do a test and will do a video about it then :)

With this driver the volume was too small, but in general when you have no resonance at all like in this hard shell, the sound gets very clean and distinct! ;)

@@mackemacchiato3238 Thanks for replying. I wish I could listen to it in first person. Well, to tune this kind of speaker low, will be a challenge then. But it complements the spherical asthetics of your setup at the same time :D

@@zenvir1680 i went to my shop yesterday and have 2 unbuilt ones and thought I could to a wooden ring and make tho whole smaller and try a 6.5” driver to get a better kick-bass maybe. Also fill the bassreflex tube with some foam to adjust the frequency a bit. On every sub I could mount a steel-pipe and mount my smaller globe on top and thus making it a 3-way system. Thanks for showing interest :)

@@mackemacchiato3238 yes, kick bass sounds like a good idea for this kind of project, although I don't think I fully understand what you said, what is a 3-way system?😅 (not an audio expert on this side, just a curious DIYer)

The 6.5” was great! The best one for Transmission line, but it worked great here also and now I out a pole on top of it and the satellite speaker on it so it became a 3-way system.

Hey man! Thank you very much! I buy the drivers at Monacor and they have replacemnet cones also actually, so if you are good with contact glue you can fix it :)

@@mackemacchiato3238 awesome! Thanks for the info. Looking forward to your next project.

Yes. But Only recorded with my iPhone8. Later edited together in the iMovie app, so no fiddling with the sound from my side. Built in BT-amplifier 2x30W

You mean like one of the Rolls Royce engines that hangs under a Boeing or something? Like a barrel shape or…?

@@mackemacchiato3238 yes!,like the rolls royce Boeing engine

@@Frambhueee 2 videos ahead of this one Bamboo Box Loudspeaker has that design

@@mackemacchiato3238 really?, I will check that out!. But you have to look at the pancin art speakers or the magic flute one

One can’t tell that after the workplace I sold it to when just a pair of these filled up a space 3 x a normal livingroom…

And also, is that why B&W does their spheres, because they hate money? Little troll

@@mackemacchiato3238 idk just because thier round on the outside doesn't mean they are on the inside, I've never seen them apart,

@@mackemacchiato3238 OK I just watched a B&W factory video. first off thier not spherical, secondly there's alot going on inside, thier NOT round balls

@@ericschulze5641 B&W Nautilus 802 , 801D And if you watched my video instead of beeing an amateur troll you would have seen they are round, so u just proved u just trolling probably coming from Ethans leftie channel where facts doesn’t matter . Hidehooo

It would be cool to burn some cool shape in clay actually :)
