Troels Gravesen- NEXT4 DIY Loudspeaker Project

- เผยแพร่เมื่อ 9 มิ.ย. 2021
- This Beast of a speaker is the brain child of Troels Gravesen of Denmark.
If you are not familiar with his work... go straight to his website www.troelsgravesen.dk/
This project took me ages to build and as the time went by I noticed that I just enjoy to take care of all the small details and problems that popped up.
Building your own speakers means you don't have to compromise.... I was not obliged to take short cuts or haste my work flow... and every bits and bolt can be bought and manipulate at will. In this mad mad world of HIFI where cables cost in the thousands the costs of producing such a speaker are meaningless. Yet again All thanks to very talented people sharing their knowledge.
The NEXT4 weighs 110 Kilo... Partly due to the Tank Wood. if you are interested to learn more please check

Let's hope for more projects like this. A feast for the eyes and probably for the ears.
Loving this comment, thank you! and yes, more is coming 😉
I am blown away with the fine work you've done. You must be proud. That's some of the finest diy speakers that I have ever seen. These and your Majico Minis that you built. Beautiful. Great job 👍. Thank you for sharing.
Thank you for the kind respond! Appreciate it 🙏
Congratulations!!! A perfect DIY build, piece of art!
Thank you appreciate the response!
Masterpiece of workmanship. Wish I could buy
Thank you for a nice video. I do really enjoy the pictures and the music you have chosen:)
Fantastic woodworking you have done too👍
Congratulation with your new speaker😊
Wow, what a great build!
Cheers from Trinidad.
Cheers mate
Wow. Amazing work. I'm always blown away by this level of talent and a little jealous truth be told! lol. Great video, nice work
I love Troels projects. He is a genius
Congrats on a stunning build... The great thing about Troels and Jantzens DIY designs and kits is that you can start out with a 16 liters 2 way in raw MDF for maybe 675$ - and still be blown away. That's my plan at least 😊 Per (Denmark)
Yes indeed and I strongly recommend anyone interested to do so
iF IS Troels Gravesen...IS MAGNIFICENT !!
Very nice build! Love the paint!
You are a star! I never built a pair of speakers but I'd love to and you are such a great source of information and inspiration, many thanks for your work!
Thank you so much for your kind comment!! Very appreciated 🙏
Wow, phantastic project, congratulations with this result. The feet project is an absolute killer! I myself made the Nomex164 Some years ago an still pleased with them, Troels is a legend!
I
Thanks! Yes I feel of late that I owe Troels a lot :)
Stunning results. 👏👏
Great video BTW 👍👍
Un auténtico artista. Un nivel de 12/10 . Todas mis felicitaciones y mis respetos maestro!!!
Tolle Arbeit...Wahrlich ein Traum Lautsprecher....Gratulation.....
Nothing but stunning speakers👍
This is craftsmanship at it's best. I've built numerous TG designs, so I know your NEXT4 sounds fantastic... but the looks... wow!
Thanks a lot for your comment! Was a tedious process 🙏
Have you ever compared your Troel builds to any commercial speakers ?
@@Smood47 I have in the past... but never in the same room, so a rather irrelevant comparison. Some things that stand out from TG designs: dry/punchy/tight bass, and no frequencies are highlighted (smooth sounding). Although the final voicing in treble is very easy to adjust to anyone's liking. I'll never buy another speaker again!
Impressive!!! If I had your skill I would definitely do these myself!! The best speakers I’ve ever heard are Wilson Sasha daw and these resemble that model a lot!!
Thanks a lot for the cool comment!
Beautiful job
Great Work Noam. I´m also a great fan of Troels Work. I hope sound great as your work. Congratulations!!
Thanks a lot for the super nice comment!
Brilliant, loved the whole thing!
Thanks!
Wow, respect. My hat of to you (and Troels) Sir!
Truly a gifted artist. Wish I could be his student and learn. I desperately want this pair. Excellent craftsmanship. Congratulations
I deeply appreciate your comment, truly humbled.
@@noamgellerdiy 👍
Can you get me one 🙏
What a beautiful set!! You are a genius
Thanks mate ☺
i love seeing what others build and this is no different great craftsman skills
Unparalleled skill, take a bow.
Thank you sir 🙏🏼
Love the see the same for The Loundspeaker II
Stunning❤
Very very VERY impressive! I wish I knew how to work with wood.
I thought I was sick . . . Actually it's a similar design that's been haunting me for years. Nice job!
Even the feet are almost identical to the ones I dreamed up
Very nice, A highly skilled guy i see.
Thanks man. Very nice execution and extremely well thought out. I have been dreaming up a Meme Set of Desktop Monitors and Satellite Subs for my own pleasure. Of course a serious worklog, but also a very Meme Type Video for Comic Relief. Your Video is not meaningless in any way, shape, or acoustic relevance. Well done.
Thanks mate appreciate your comment 🙏
just WOW!
Ausgezeichnet!!!
Superb job, would love to hear a sound demo ( certainly not the crap you played in the back ground in this vid ) I have just ventured into DIY, ordered the Troesl Discovery 861 kit, should be here next week, looking forward to it ( not exactly a Next 4 but a start )
Thanks! Well about the music... TH-cam blocks 99% of all music, because of copyright issues. trust me I tried everything. What left is either classical or rather obscure music. I still think Verdi requiem is awesome thou
Very nice work! I hope you have alot of fun listening to them!
Can you compare them to the ATS-4 from the same designer? What made you choose this one over the ATS-4?
Thanks for the compliment! Well, I went for the next4 because I already had some of the drivers at hand and knew what I am dealing with... the seas nextel line is fantastic, detailed yet somehow human... the audio technology drivers would be probably better... at a price! I am building now the TL2 design. Let's see how that goes 😉
Nice 👌
Love the listening room as much or more than the speakers. What was the total cost, and how long to finish?
Thanks! Well the room is an ongoing project, 4 years in the making now... about the price, I would guess under 4000€. As I've done everything myself I had to pay only materials and naturally, it makes a huge difference in costs.
I have been following Troels for years. Never made a speaker though! Just don't the workspace. Very imposing speakers - well done.
Thank you sir, appreciate it! Cannot recommend his speakers enough
Hi, Very interesting to watching your construction of these cabinets, I have been looking around the universe for different ideas, I noticed you have made quite a few different types of loudspeaker cabinets, And noticed that you are using drive units made by Seas from Denmark .
I enjoyed the piece of music that you were playing in the territorial which sounds very nice coming out of my transmission line loudspeaker cabinets that I built 40 years ago, And I am looking at changing the drive units as the Tweeter has packed up on one of them, And I was recommended by a company over in the Uk to use the drive unit made Seas, What is your opinion of them, I am not very good at electronics but I am very good at making work as this was part of my trade a few years ago, I’ve just realised that this was downloaded to TH-cam a year ago. So not sure whether you will pick this up or not, Great territorial I’ve just been looking at some other ones of yours as well. Phil from the moulin France.
Hi Phil, good that you wrote.
Seas from Norway makes wonderful drivers. They have a line for every budget. The drivers I am using in this project are called Seas Nextel. Those are paper coated drivers... in my opinion, those are some of the best drivers one can buy. But that's really a matter of taste. If you'll search in youtube for "Bifrost-Scan speak vs Seas" you'll find an interesting video comparing the sound signature of both companies. Be aware though that changing drivers in an existing loudspeaker will aquire a new crossover and a very talented speaker designer with special equipment... have fun and good luck!
@@noamgellerdiy Hi Noam , thank you for your reply and the info, I will have a look 👀 read about them as you say I will probably have to get somebody to build a new crossover unit for me, My problem will probably be trying to find somebody and obviously the cost of the crossover unit,
About 40 years ago I had a colleague who was good in electronics I brought him a special microphone as mother bits and pieces and he built the crossover unit after two or three weeks of testing late at night one 2 o’clock in the morning when his children and everybody else has gone to bed,
Anyway thank you for your help I will have a look at scan speak vs seas.
Phil from the moulin.
Beautiful work!! Very, very nice. Do you have an idea how many hours you had into this build? I think you said the speakers cost about $4,000 in parts and materials...
Thank you Mark! Yes, money wise-4000$ would be about right. I never count the hours I spend working... since I take it as therapy session 😉... all I know is that it took long long hours.
also a great Room .
I would love a serious plan for this! Just to put my head on and to understand if I'm able to replicate.
Greatt.....!!....Ji Ji Ji ... Saludos
VERY nice finish on the MDF panels! Did you use Jantzen iron core with disc inductors for bass? I wonder which is better, the discy the discless one?
Thank you! I never use MDF, only plywood beech.
Without the iron core are supposed to be better. The ones who use flat copper are even better.
At 7:35 there was a visible iron core inductor (grey disc top)... @@noamgellerdiy
@@staLkerhu true! Already forget... if you are interested check Troels Gravesen website, there's lots of information over there
Hey, I'm an audiophile bullshit type and in no way does CLD represent snakeoil. Lots of cool potential uses. Super nice builds btw. Very clean and professional.
Very nice but how do they sound?
Enjoy man!₩
A sound demo would have been nice. How much did it cost ? They remind me of simplified Wilson audio speakers.
When you listen to a sound demo on TH-cam you are actually listening to your own speakers, not the ones in the video. There is nothing to be learned from this.
Nice work ! I wonder how much each speaker weighs ?
Thanks! If I remember correctly about 110kg each. Panzerholz is really heavy..
Impressive work. How much do they weight?
Thanks! About 90 kilo
impressive attention to detail .oh the audioplile on a budget page on f book is pretty snarky and snooty . You had me laughing . Thank you!
Could you do a demo?
great, can you give the dimensions of these speakers (width and height)
👍
👏...
Hi mate, how i can contact you for speaker build up, do you have any web page?
Hi, would love to read from you. You can write me at-

I'm gonna build one of his projects but I'm going to use an MDF product called glacier green which is used in high end painted kitchen cabinet manufacturing. I somehow don't like the idea of using ply. I also would hae a preference to use all Scanspeak drivers. Wonder if that is designed?
Sure, strongly suggest to look at Troels Gravesen website, he works a lot with scan speak drivers.
@@noamgellerdiy Already been there before your video. What kind of $$ did you have in this finished project? I am more than capable of ding the work. I have 10' x 5' CNC Router with ATC, and mainly FELDER machines in my shop. This is likely my net project but not sure my approach yet.
@@philstevens9914 the next4 kit costs about 5k. So High End for small money. I have just built the CNO4. The CNO4 is the better loudspeaker....
@@noamgellerdiy The investment cost is peanuts compared to buying Wilson's etc. I'm also looking at subs and also amplification. You build amps right?
@@philstevens9914
@philstevens9914 absolutely. My reference loudspeaker fron Troels is the mighty TL2. It is I think the best he had done, apart from the latest A50. I do not build amps... but the TL2 uses tge Hypex Fa501 delivering 400watt in 4 ohms to the 18inch BMS woofers. No need for subs.... and no need for expensive high watt gear for the upper module since you can biamp your speaker either with SET amp ( tubes) or First Watt J2 ( Nelson pass) with 95db the TL2 will rock also with 20watt.
those look great gee whiz !
Super project. But the colour looks like plastic from tv from the70s.
👋👍👍👍👍👋
Hi Noam! Would you consider selling them?
Already Sold!
@@noamgellerdiy Bummer for me!
Would you sell those?
Already Sold...
👍♥️🫂
Cool as a sob
Not a fan of the seas nextel coating used on these drivers. Actually not a fan of seas drivers in general. Shame you didn't opt for better drivers but since you were using someone elses plans you were limited.
No worries, each one as his own preferences.
Cool name btw
unfortunately no real music demo.
there is another video
That's not CLD. This is just a vibration isolator. CLD principle works by *bending a wall* made of sandwich material. By your logic you can call a shock absorber in a mountain bike a CLD. Makes no sense.
Constrained layer damping (CLD) structures, which are one of the composite structures with a softer viscoelastic material (VEM) layer sandwiched between a base layer and a relatively stiffer constraining layer, are widely used in engineering applications for reducing vibration and noise radiation.
As I understand magico mpods are built on exactly same principle, just different materials. Btw I’m a juggler too.
@@noamgellerdiy Yeah, we talked on fb. We meet again, lol How are you doing?
I see now you're referring to Magico's marketing material. I'm sorry, but it's just jabber, they're... stretching it :)
If you look at a bicycle fork, it has elastomer piece sandwiched between stiff lower and upper fork parts :) It doesn't make it CLD yet, just a damper. CLD sandwich dampens when a panel is bent. It dampens panel resonance which comes from panel's own elasticity. The viscous layer stretches under shear force and then slows down the panel on it's way back effectively damping the panel resonance. When you support a box on viscoelastic feet you're not utilising this principle. You're just isolating vibrations, because there are no significant sheer forces on a single point support. You might as well put it on springs covered in damping grease - same thing. The thing doesn't transfer the vibration to the floor, but it doesn't damp it either. It's a vibroisolator. The same stuff is used on industrial machines, just a bit bigger.
Magico calls it as they do, because it's a buzzword on the internet, I think.
I learnd something New! But I wont edit the Clip.. with my editing skills it will take a month ;)
@@noamgellerdiy yeah what he says is true, it would make more sense to make the enclosure out of 2 different materials and viscoelastic layer between, much better than just normal enclosure
to bad he doesn't sell any of those speaker Kits..
