DIY Kerf Cut Speaker Cabinet // Build Plans

[@bertfriedman]

Wow I'm a little Speechless. Just one of the most beautiful and detailed speaker buildouts I ever watched. I learned so much from watching this. Absolutely amazing work there! Kerfdos to you!

[@ritesbarik591]

This is the first time i've seen anything like these brilliant looking two way enclosures man. Your designs are worth of praise and your simple yet sophisticated woodworking tools and your custom crossovers are very much appreciable. Apart from drivers everything here is raw DIY man. Good craftsmanship. Goodluck Erik

[@detlevpomp]

Hammer, ganz klasse Job gemacht. Schön, wenn ein Mensch sein Handwerk genau versteht und es so gekonnt umsetzen kann. Respekt !👍

[@erikkroll2154]

Very nice! That is some real wood working, there! Looks like your woofers were out of phase with each other. Nice build.

[@weaponisedpotato7352]

I really like this build. Possibly the best speaker enclosure build I have seen on KZbin. Sub'd

[@focus-digital-marketing-ai]

Beautiful work! really dig the asymetrical front design

[@alexandredidierjean8413]

what an amazing build... stuning. you could look into adding material on the bendy part to add rigidity to prevent deflagration. I can t wait to buil my next speakers..

[@jungtarcph]

I was going to ask the same, maybe put some glue or filler in it to strengthen and minimize vibrations

[@Prinkiestonkie]

Really love these speakers, very well done! Also great selection of background music;)

[@Erikdidit]

Thank you! :)

[@kiweekeith]

Congratulation, great vidclip .... Just love Your Work, you just have to be happy with the end result, they are Stunning, Great Workmanship .... Very Best to You and Yours from New Zealand

[@potsy9973]

Those are quite cool looking. Good way to combat standing waves too.

[@carlospontini]

Joli travail, appliqué, sans chichi, ça donne envie d'écouter...!

Lovely work on the kerf cuts, a real pita to do properly

[@Campbell1.]

WOW, I wish I had the talent and resources to build speakers. Very nice indeed

[@oktan375]

Yes wow too of me ✔🤣🤣🤣✌

[@marklavric8323]

Bravo!!!!!! Fantastic. I am sure they sound as good as they look.

[@pankajphand3569]

You are master craftsman Keep posting

[@rcmoot]

What order crossover and what Hertz rolloff did you use? That port is huge for a small cabinet. What's it tuned down to? As you can tell, I build high class 3-Ways. 2 ways just do not give great depth . Most sound too neutral. Looks like you had fun. Keep spending more and building better.

[@juananeski8369]

Me encanta tu trabajo.., solo una duda, respecto ala parte trasera interna.., esos cortes permiten que se doble y tome una forma curva, pero- y he aquí la pregunta- ,sirve también para asuntos de acústica interna? (.Por ejemplo en el diseño de las keef LS50 tiene detrás del midwoffer una especie de laberinto, que impide las refracciones internas de la caja.) Hermoso resultado,un saludo, estaremos atentos a tus vídeos!

[@chuckwatts841]

love the asymmetrical/symmetrical lamination of wood for the face plate ... very nice tough ,,,

[@jayweb702]

That was beautiful, perfection on every way!

[@AlOne-xg6dv]

Very nice job. Beautiful and well made.

[@chrisgblues]

Probably the most satisfying speaker build I’ve ever seen. 👏

[@JukeboxAlley]

That was an amazing build, ive built a few sets myself, that is genius how you made the cuts to curve it and filled with glue, how far apart are the cuts for the bend and is it high density or medium density fiberboard? Very nice craftsmanship, better than alot of high end overpriced speakers ive saw.

[@FirstLast-jp6he]

Beautiful, proper and neat. Well done.

[@АртемВахмистров-ж9х]

расскажи о фильтрах, как ты их подбирал? емкости катушек, резисторов и конденсаторов? акустика автомобильная? объем корпусов рассчитывал?

[@MichaelAmster]

Did you choose not to do a fiberfill for the cavity? Did you run software to choose the Q of the drivers, the dimensions and the crossover frequency/slope? Great build btw.

[@Erikdidit]

Yeah i filled it with polyfill. I usually use winisd to calculate the cabinet and xsim for the crossover. I can't remember the crossover point tho.

[@bhairava2020]

You're a master of your craft!

[@rough5123]

Looks great! No stuffing needed?

[@thegigisup_studio]

Yo! Those are sick! I would definitely rock those in the studio as a high-end hi-fi/mastering reference 😎

chega me da alegria ver um bagulho tão bem feito !!! mds mano

[@erikkroll2154]

Those are great drivers. Nice build!

[@stephenbrowne33]

7:55 the drivers are moving out of phase?

[@lamatyler]

wow good eye!

[@OstrichWrestler]

It might actually be because of the rolling shutter of the camera. If you look at the cones themselves they are distorting because of it as well.

[@Erikdidit]

I think that as well. I am pretty sure I didn't connect them wrong but I can't be sure.

[@stephenbrowne33]

@@Erikdidit I would assume you would hear some cancelation and lack luster midbass and lower. It just looks that way on film.

[@UberAlphaSirus]

Regardless of phase, the music was shit! An auto tuned moped sounds shit IRL and from the worst or best speakers.

[@thomascalvert7894]

Thankyou very much,now to convert my keffiyehs speakers into this artistic version,Cheers Tom

[@thomasschafer7268]

You can buy folded MDF 12mm. Only one for a box is not enough. Better resistors and 400v Caps are not expensive.

[@nZoDesign]

High level design. A pleasantly original aesthetic. One downside to the feet spoils the rendering. Very nice !!! Une conception de haut niveau. Une esthétique agreablement originale. Un seul bemol les pieds gache le rendu. Very NICE !!!

[@Erikdidit]

Thank you, the feet are temporary, they are meant to be wall hung.

[@nZoDesign]

@@ErikdiditTrès bien j'ai hâte de voir le résultat. Very well I can't wait to see the result

[@2869may]

Great looking speakers...! Can't believe you didn't fill the kerfs with Bondo...

[@rikardekvall3433]

Hi Erik, did you fill the kerf cuts, with glue? Hard to see, or did you cover them with HDF? Great build! Wish I have your workshop!

[@Erikdidit]

Sawdust and wood glue 👍

[@ingalook]

Nice... tweeters with a grill this time... learning from the last video :P

[@aikes.2200]

Very nice Craftmanship! At which Frequenzy did you cross these over? The RS225 doest play well, above 1khz, or am i wrong?

[@Erikdidit]

Thank you, i can't remember where they are crossed over. I would not play them a lot over 1,5khz.

[@leroyjamesc]

That is one stunning piece of work!!

[@manosprotonotarios5187]

amazing work and shape - i would expect the curved part to be subjected to vibrations, is this the case?

[@jonathanwong880]

Superb workmanship!!

[@hdmccart6735]

If they sound as good as they look - very nice!

[@Indi_Hodophiles]

Hi. How are you going to hang them on a wall without blocking the rear port?

I haven't noticed any problems yet 👌

[@Vario125HID]

very very very nice build !!!!

Very good sound track!

[@jungleb]

Amazing Job!

[@sandorignacz]

Congratulations, very good Professional work

[@MortenSminge]

would have looked awesome with a stand made out of a white pipe and and a floorbase of the same wood as used for the front. Nice build though!

[@Erikdidit]

That's a good idea but they are actually meant to be wall mounted

[@ASSOpid]

Did I miss the part of the video where you filled in the kerf cuts?

[@Vibration_Crew]

Seems they weren't filled in. As a suggestion, next time use a mixture of wood clue and the excess wood dust to fill in the kerf cuts. You have basically thinned the wood panels top and bottom of the speaker and these still need to be the same thickness of wood as the sides. Basically fill in the kerf cuts. Nice build tho.

[@roshanmenezes3299]

Beautiful Looking ones!

[@Erikdidit]

Thank you!

[@jasonleigh5767]

Very nice speakers do you make them to sell

[@Erikdidit]

[@jobbagyferi]

Check polarity on the speakers. 7:55

[@Tony-Tequalla]

Nice speaker build.

[@Rastapapulus]

Check the polarity of speaker wires again, especially woofer cables and circuit.

[@ExtraKimB]

Riktigt snyggt! Jag hade dock, som flera andra påpekat, valt att fylla rundningarna med lim eller plast.

I just bought new Bosch POF 1400 ACE router, I want to know what type of Bit you are using to create those circles at 4:09!!! Need name of Bit and Size you used... Great work !

[@Erikdidit]

Thank you, I just used a regular straight bit. The size doesn't matter. I usually adjust my circle jig to make the groove wider if necessary.

[@arfathkhalid1099]

@@Erikdidit is there any video where I can see how do you do it?

[@robertmoi8400]

Great design, cabinet, and drivers but why electrolytic capacitors especially on the tweeters? Even budget factory speakers don't use electrolytics on the tweeter and are usually trying to save every dollar that adds up in case of huge volumes. For less than five units, the price difference between electrolytic and polypropylene caps is negligible but the performance difference is huge. Your speakers won't reach their full potential with the electrolytic caps.

[@Πέτρος-υ8η]

What about amplifier. Are you satisfied?

[@Mikiemike0051]

Really enjoyed the vid and how they turned out. Are the crossover specs in the plans as well, and being that these are 4ohm are they wired in series to present at 8 or you just use the 4ohm amp in the description? Thanks!

[@Erikdidit]

Thx! The crossovers are in the plans as well. The speaker impedance is 4ohms with the crossover and speakers.

[@ЕвгенийПетрович-щ9п]

[@visghost]

well done, and not one dislike

[@Florian88888888]

ither those are som binaural beats or you might have gotten the polarity wrong. the slow-mo in the end suggests that.

[@Erikdidit]

The polarity isn't wrong. I know it is the camera fooling you :)

[@SmR8008]

I love the style of these 😊

[@malfeitorgai9112]

Not sure why you would run the woofers out of phase in a room that size. Also they are not traveling straight -sans LF motors should be more barycentral to the internal volume for that design to keep the pressure distribution from dragging voice coils. Nice cabs though

[@izoyt]

great build. but way too big logo. keep it discrete, it will go with otherwise nice design much better.

[@dovydasvilcinskas3834]

Looking very nice, how do they sound? Is there a frequency graph? :)

[@Erikdidit]

Thx, I'm very happy with the sound. I know I have measured them, but I have to check my computer to find the graph :)

[@thomaslindroos1667]

Excellent build, very nice cabinets. What did you like and dislike about these soundwise?

[@Erikdidit]

Thank you! I really like the punchy bass from the woofers. Not much I dislike but the size of the cabinets. I had to make them this big to make them play low enough.

[@jakob1379]

@@Erikdidit Couldn't you have ported and insulated them to go lower while decreasing the size?

They are ported and i used polyfill

[@apofiszz2193]

Как вы рассчитывали частотный фильтр?

[@warpspeed9877]

You kerfed the top and bottom and you used the round forms to keep them in shape but how you reinforced the ultra thin remaining? Usually a mix of sawdust and glue is poured into the slots to take up any open space and strengthen the wall but I didn't see you use any ...or it was skipped in the video?

[@Erikdidit]

I didn't fill up the whole thing but some. With the front and back baffles glued on it is steady

[@flepper231]

@@Erikdidit But now you have ultra thin walls on both the top and bottom... That will let a lot of unwanted sound bleed through. Have you done some measurements?

[@Erikdidit]

Yeah, I did measure them. I can upload the results in the shop on my website when I get to my computer. I don't experience any issues at all

[@GSP-76]

Awesome speakers! The stand needs a little work, lol but great job!

[@julietphillips1991]

Quality stuff!

[@Rendraco79]

those are a nice set of speakers, good design, but as usual for me, a lot of room to improve on it. I would be more careful in the assembly and structural develop and manufacturing than the aesthetics and take care of the advantages of the wood in the design applied on aesthetics. anyway, nice video, and beautiful speakers. greetings.

[@m-tech1816]

I don't think you want them to be wall mounted. With the port on the back they need a good amount of space back there. Otherwise the techniques are superb, really love the rounded design of the top and bottom.
