Building a Bluetooth Speaker! AWESOME mid-bass and portable!

I recently decided to build a bluetooth speaker, my goals were to make it sound great, be portable, have a good amount of bass and natural highs, and to look awesome. I actually ended up building 9 of these! Watch as I build step by step this bluetooth speaker using the Dayton Audio KAB amplifier boards and added lithium ion batteries.

when will you start making the Rafa's Mom commemorative wall placards?

[@mikebiron7339]

Or, get you a old t-bird to rebuild the engine, a couple times......LOL

[@adven0018]

No scotch brite pads. You will get a fiber in the heads.

[@ghandtlg5898]

love that fluid design; 1 tweak I would add is a recessed handle on top for ease of portability

[@TripleSplashAttack]

I teach middle and high school kids how to fabricate 5W speakers costing about $25 each in materials. What you did here just blew mine out of the water lol

[@CarAudioFabrication]

Cool that you teach them that! Show them these videos! Everyone starts small but as you learn you can do more involved cool things, I'm still learning too!

[@craiggus365]

Kudos to you. This kind of sometimes becomes a lost art as far as the design aspect. We all could just buy stuff, but knowing how and why it sounds good is the heart and soul of audio. I'm an old guy still messing with audio and the skills I learned along the way were more than worth the pain. Please keep teaching kids this stuff, it works!!! +1 CAF - Great Video!!

[@kristoferbrown8007]

I like the unique shape of the enclosure. I don't think people fully comprehend how much time is involved in designing, routing and laminating all of those components.Even though I wouldn't have taken the time to do is that way, I certainly appreciate the amount of time it took. Fabrication is clearly your passion, and you're doing it right. You keep the raising the bar, and that's really important in my opinion. Kudos to you my man.

[@mattalones93]

Daupe AF, per usual ;-) My friend teaches shop and will be interested in this, especially if he can get the school of buy all the parts. The kids would love these!

[@legion2k988]

I do a lot of CNC routing. One thing that I do that helps with pockets or say your flange for the speakers. You don't really need to pocket the area that is going to be cut out. So I'll draw another circle about .125 inside the area that is going to be cut out and discarded. So that it only pockets the area needed and doesn't waste time pocketing the whole area. It's only a few min but when doing a lot of them. It adds up. Even more so for larger speakers or cutouts with a lip. Also, I use 3d tabs.. This keep the router moving and I don't get the little marks were the router went over the tabs. I've found that about 1.5 inch tab at .22 works great for me. The .22 is because I normally use a .25 bit that takes .25 out on each pass. So .22 is less than that so I only see the tab movement on the last pass. Just food for thought. Good work and I love how clean your shop is. Giving me ideas. ;) Also, I use a oscillating cutter to cut the tabs. No blowout or splintering. For the inside corners you can use dog bones. There is a plug in for fusion that will find and create those for you or you can do it by hand. I like dogbones.. not T-bones.. but that depends on the location and needed.

[@Bradykottkamp]

Need the .stl file to print that kick ass cover plate. Great video Mark!!

[@kakurerud7516]

those specific digital amps are super efficient. i was able to drive a set of speakers with pretty good performance off a 9v battery that was too dead for a smoke detector (just for fun) and its been pretty lasting.

[@connor8560]

I have made a speaker system at home and it is the best sounding speaker I have ever heard. I have 2 5 1/2 inch woofers 100w each with 2 1 inch tweeters and for the low bass ive got a 15 inch subwoofer running on around 500w and 2 8 inch midbass drivers on 100 each. It is extremely loud but it is the best thing i have ever heard

[@prenevenprezznaidoo2056]

How's a give away for one of thoes lovely speakers

[@twiztid6977420]

So, how much you selling them for?

[@Skimdude6r8]

Awesome build. Love the extra little touches like the front. Thank you for sharing

[@ManniV]

Great work as always Mark! I was attempting to build something fairly similar to this in 2016 but ended up putting it on the back burner. Seeing this (and that you made 9!) makes me want to get back to it and finish mine up.

[@TEAMKONGGA671]

Always enjoy watching your builds. Been tuning in on your vids and I gotta say you've come a very long way with your shop. And the amount of different tools you use to do these builds. I wish I had a shop like yours. Keep up the awesome builds and videos.

[@DadsRCGaragePNW]

Interesting build. Needs handles to make it portable an maybe a bedliner. Also how much air space did the amp take up. Did you add the difference to one side? What freq did you tune to?

[@goodgoat3096]

Considering all of the additional work that went into the cabinet to arrive at a non-box shape, I would have went with a separate tweeter and a higher end set of more efficient speaker drivers which would provide more volume with the same amplifier power. That being said, the speakers are unique and beautiful and sound pretty good on my headphones. Great job.

[@sirtanon1]

Mark, you've done a fantastic job with those! They look so professional, so polished, and so consistent. I'm thoroughly impressed. Then again, I'm usually impressed with the work you do in every video. What do you plan to do with those speakers, since you've built 9?

[@samdavies6404]

Very nice dude. Especially likening the darker stained oak not to keen on the really light one kinda cheapens the look of an expensive wood like oak to something more like pine especially if people can't see the difference between hard/soft wood and make judgment based on colour (you wouldn't believe how many people do actually do this) but amazing work man love it

[@thomaslindroos1667]

Awesome! that curved wood was a really nice touch and I will try to implement that in my next speaker design.

[@CarAudioFabrication]

Glad you like it, it was a subtle touch but I'm happy with the way it turns out.

[@calebs.2166]

Hi Mark, first absolutely fantastic job! I love the entire channel and am proud to be a subscriber! Every video is very educational and creatively inspiring! I do have a question to follow up - what CAD, CAM, and controller softwares are you using to incorporate the CNC work into the project? The tool path graphics preview of your cut pieces in your CAM software looks super detailed and accurate! I have an older CNC router setup and I am looking to upgrade my user interfaces. Thank you and keep up the amazing work!

[@jlg23us]

Great job, been looking at the same kit. Good to hear your feedback about it, thank you!

[@CarAudioFabrication]

You will like it, have fun building!

[@HifiVega]

Awesome build! I’ve been wanting to do something similar for a while.

[@Digging4evidence]

If you were to add a carrying handle, what would you have chosen? A simple luggage style running the center depth or one that spans the entire width and is mounted to the sides? (That way it can rotate underneath the bottom of the box and function as an upward prop.)

[@adven0018]

Awesome, just awesome. Well done.

[@thds4815]

it's a pity the volume control is on the back, did you tried to change the equalizer of this dayton diy amplifier with a computer ?

[@abeldiaz8082]

That sounded great..better than some other ones they sell at the store

[@somethingshort01]

You only made 9, should have made 10! (Mine) awesome work dude. I enjoy watching your videos, keep learning, and keep teaching us.

[@CriticalTechReviews]

I want to see you do this but with larger drivers. The fabrication is absolutely exquisite (as it is with everything you do!), but it seems like overkill for such small speakers, even with a ported enclosure. I could be wrong though, maybe it does require that much airspace?

[@crazy8sdrums]

Those look tight! Great DIY project!

[@TheRattleSnake3145]

That method must use a butload of wood per box.

[@brettrobbins5182]

Well done there, ol’ Mark!

[@allofmeirl]

This is next level. I really like. Well done!

[@subspaceanomaly]

It would have made more sense to have the bottom plate removable than the front panel to avoid those screw holes. It would also have made more sense just to make it from square sheets rather than glueing all that mdf, or build with a few extra panels and reshape to get the curves

[@salvadorcisneros]

What's up mark that bluetooth setup is pretty cool bro keep up the great work...

[@djluvbite]

Well done mate!

[@chitresh6582]

Awesome job man Just add a handle for portability

[@fareedrakeib1288]

neat job , well done from what I could hear sounds pretty good man

[@J.ortegadesign]

Great build!

[@Wickstacular]

Nice build Mark! Going after Diamondboxx I see. ;)

[@SkyJUSTIN6]

Hey any idea on how to stop my widow rattling when it is up ive reduced 99% of rattle from my car but now im stuck on the window thanks for your informative videos anyway

[@bankal1442]

Great job man, really :)

[@buckbundy8642]

I like it. It’s awesome.

[@madmikesprops]

Super rad Marky Mark. I dig it. I have numerous uses for that blue tooth system and I plan on checking it out. Thanks for sharing that product brohammer. I plan on being a patreon supporter as soon as possible. Your videos are very helpful/inspiring. Keep slayin it.

[@Mrcaffinebean]

Would love to see more design details since its of course the most important part. What program is that? How did you determine the optimum volume and do the tuning? How did you match the curvature of the speaker flange?

[@CarAudioFabrication]

I'm a Mechanical Engineer. Design is in my genes.

[@blaineedwards6943]

You do great work

[@CarAudioFabrication]

Appreciate that thank you

[@jbkibs]

nice work! thanks for the info on the kits.

[@_PsychoFish_]

Amazing build! But I have one question: A lot of portable bluetooth speakers rather use passive radiators than bass reflex tubes (probably for splash resistance and size). Is there any particular reason you chose a port instead of passive radiators?

[@garyoog]

where can i buy one ?

[@dayngerkat6760]

When Mark at fab kitchen makes a speaker you know it’s going to have 3 qualities: 1 well built 2 good sound 3 classy. Could you make a durable portable Bluetooth speaker?

[@CarAudioFabrication]

Thanks! Thought about it, I would use acrylic and coat with duratex. Probably make it much smaller.

[@dayngerkat6760]

CarAudioFabrication I’d be interested in buying one. I live in Hawaii and need a good sounding, durable speaker to bring to bbqs on the beach 🤙

[@kyriacosdavis7781]

Do you sell the back plate that you design?

[@derrickcarter4127]

dude I love that bluethooth speaker I would like to have one

[@sallopez6676]

Always a class A design nice vid bro

[@PetreAdrian]

i think fully 3d printed full would have been easier - sooo much work - and would be interesting to see how it sounds fully 3d printed - still amazing finishing - how long did it took you to make one ?

[@CarAudioFabrication]

Too large for my 3d printer. Maybe for a much more high end machine.

[@shaunjay6040]

What are your thoughts on using a 3-way component system in an spl set up; would the components be loud enough or would one come out better using midrange speakers and super tweeters?

[@jasonastor4370]

Nice man. I always wanted to make one of theses!!!

[@ronjlwhite8058]

Sweet job on the build Mark. What are you doing with them now???

[@Cephalon_Shade]

Looks awesome!

[@johannessilalahi1178]

Good job

[@RG-nv3gw]

Nice build. How do you feel about walling off part of trunk to enhance bass and cut down air pressure that may add to trunk rattles... the sub box would be on the cabin side of the wall and air would travel through rear deck. I'm interested in your feedback

[@ahmedgerges3955]

very nice job ..

[@tamojitsaha1128]

I really liked this build. Great work! I would love to have subwoofer in this portable build. Do you have any suggestion ?

[@joseballin5141]

muito bom, sao sempre lindos os teus projetos, parabens.

[@orionthehunter9107]

Nice looking speaker. From my end it sounds great. Very crisp. For myself it's kind of large. Do you have anything that's maybe half the size that's loud clear and has some good low end?

[@kencohagen4967]

I love it, but where can you get the cabinets? I don't have the tools to build one.

[@michaeltenala2036]

Wow..I like it

[@ruikazane5123]

Next: a BoomBox?

[@daz5122]

X-Carve is cool.

[@ethanheaton8109]

That looks awesome keep it up man

[@CarAudioFabrication]

Thank you

[@arturodiaz4106]

What CNC machine do you use?

[@justlooking813]

I wish you showed the wiring work.

[@Harry1996]

send one to unbox therapy, he has heard almost every bt speaker needed to say if its good enough

[@ezequielparra1854]

Love it man

[@darksbacon5856]

I went with the 50*2 watt amp what would be the best full range speakers to go with it

[@JungYT]

What software is used for modeling?

[@jtuck6065]

Definitely would like to buy this setup if you offer it 👍🏻

[@Troy_Audi0]

DUUUUUUUUUUDE! your build is so much better than the demo ones they show on the PE site.. killer job

[@kid_rajah]

That’s actually not a bad sounding speaker. My question is what is your favorite material to use for the feet?

[@CarAudioFabrication]

I linked the ones I like in the description

[@kid_rajah]

The only thing I would have done differently is I would include a separate chamber for the internals and BT processor. It may not make that much of a difference but that’s just my perfectionism helping my ocd. Lol

[@DrGeta666]

the larger space will help with airflow, the amp isn't big but it will make heat and a small chamber holding the internals could overheat depending how small it is.

[@SRICHALPHA]

Is it possible to build a custom subwoofer box for a 2009-2014 Ford F150 SCREW specifically 2013, behind back bench seat? I'd like to know your thoughts. I've been struggling with the idea and it seems it's not possible according to forums

[@tjablaj]

Really beautiful Mark! I got a question for you, a little bit off topic thought: What cnc machine and cnc program do you use? I want to buy one cnc for myself since i got so many ideas in my head but i don't wanna buy anything for like 2000 dollars or some cheap crap, just something easy budget one to start with and to learn on since i have never use a cnc before. Would love to get some help! Thanks

[@drunkenbass6128]

Hey mark, what program did you use to design the box? Google sketch up?

[@bobkeller8383]

How much did these sell for?

[@welcometomychannelswelcome7261]

nice shape. great design I saw u had a lot of them. I assume u r going to sell them

[@JulioHernandez-wl1kc]

Any way i can purchase any of those back plates from you??

[@CarAudioFabrication]

Shoot me an email via the site

[@JulioHernandez-wl1kc]

CarAudioFabrication email sent. Thanks !!

[@RobRealistic]

I want one. How do I get one if these. How much?.

[@christianbernheim4505]

What is that 3d program you are using?

[@berniebadboll3571]

Anyone know this answear?

[@lewisochoa2761]

Nice build. It would have been nice if it was actually connected via Bluetooth though.

[@BIGTAGGART]

How much can I buy 1

[@frankherrera4044]

Awesome 👏🏽👏🏽👏🏽👏🏽👏🏽

[@JoseHernandez-tc1kl]

Wow that is cool.

[@davidfoster1151]

Excellent build! Not as if you need to be told though. I only feel compelled to comment because of the thumbs down and negative comments. I also have wanted to do something like this and in the past actually have. My build was way overkill in the amplifier which led to poor battery performance. A project like this takes a lot of design consideration and may require sacrifices in areas to accomplish the end result. It’s real easy to to be critical especially when you have limited real experience. I feel that is the case here. Everything about this build is top notch. This guy is an epitome of the new “maker”. He took an idea and set a goal. He then made that idea come to life through design in CAD, CNC,3D printing, and wood working. Oh...he also filmed it to spread the knowledge! So you delusional idiots should keep your comments to yourself. You only make yourself look ridiculous.

[@suzukiman650]

Did you make the speaker look like an upside down Wall-E head on purpose? lol

As a wrestlingfan, all I have to say is: "THIS IS AWESOME!"

[@cross_fire_]

I want one so bad

[@SlayerHawkX]

can i buy one!!

[@stanleymesje]

Are you gonna sell them?? WANT ONE! ♡__♡

[@mesharyhd7646]

What program you are using for 3D modeling?

[@CarAudioFabrication]

Fusion360

[@ryerye700]

I want one

[@richacevedo660]

which model CNC are you using?

[@jeffferguson378]

Looks like an X-Carve

[@satanas666reyna3]

So bad ass
