Not sure if someone has mentioned it, but as someone who has worked in a glass shop for around 5 years I've used A LOT of that weldon stuff. The best way to apply it is to actually put your parts together and then apply the weldon to the seam and let it wick in. You'll instantly see it starting to melt the acrylic together.
Ahhhh now this is a good tip, thank you! The applicator makes way more sense now
Really nice work 👍
I like this project so much, I might have to copy these. A diffusion dome or panel would be a good idea.
That is DEFINITELY the way to solvent weld, although for the best seams he really should have used UV cure glue to avoid microbubbles.
As an actual acrylic fabricator, 100% agree, it works by capillary action, like water it will flow into the gap
I came to say this as well... only way to do it.
Wire strippers at 13'27" - A little tip for you. When you strip the end of the wire, leave the excess insulation ON and use that between your fingertips to twist the strands, THEN pull it off. That way you don't get finger grease all over the strands and it makes the solder joint more reliable. Great video btw!
Yeah, or you could just, you know, not be a disgusting slob and wash your hands after you get done eating your jar of mayonnaise.
Also, those type of wire strippers are pretty trash in my experience. Get some Jokari or if you have a lot of money to waste some Knipex or Wiha ones. The Jokari cost me €12 and were well worth it. Great Scott! recommends them as well.
Wow, not sure how I didn't know that trick. You learn something new every day. Thank you for that comment. Whether he learns from it or not, I just did.
My Dad taught me this when I was a nipper. It also makes it much easier and quicker to twist the strands as you can just roll the insulation between your fingers.
You cannot make a speaker sound it's best in a cabinet without knowing the free air resonance, and the same goes for the port size/shape/type.
The acrylic probably resonates, the woofers are rather nonlinear, there's a lot of problems with the built. Nonetheless, it looks like a fun project.
I don't think good sound is his priority.
my point EXACTLY!!! without knowing that you are just fooling around in the dark!
The C-Note MT kit has the cabinet panel dimensions laid out for you - figuring out the interior dimensions from the MDF plans is pretty trivial. The crossovers and ports are part of the kit too.
I suspect the mismatch in resonances between the hardwood and the acrylic might actually help his sound out, but I'm not sure. I do wish his skyline diffuser was down at listening level where it's supposed to be though 19:02. That's not just decoration...
This is a kit wiseguy
can we talk about how cool the post mortem aspect of these videos are? like no one else does that, and its really helpful to see how to improve something.
It's a good outlet for me because I always find 10 different ways I could've done a project better by actually building it. Designing is one thing, but going hands on makes things a lot more clear
@@ZacBuilds yeah i just finished my first project, and it had so many ups and downs so it was literally a roller coaster of happiness and sadness while making it lol.
Yes, I totally agree. I had stumbled upon a few Zac Builds videos, but was never compelled to subscribe. (No offense, I am more of the long-time Adafruit customer, "RIP Philips Hue & Govee" type than I am the "tear the guts out of a Philips Hue" type.) However, it was the Post Mortem aspect of the videos that finally earned my Subscription.
+1 for the post mortem! "Lessons Learned" is essential for everything from fabrication to car repair to gardening to IT because if you don't do that, you'll never be able to improve on future designs. This is a perfect example: Now you know you need to measure ... well, "everything" so that you don't have to cut away wood to make room for LED or crossover assemblies should you ever decide to do another speaker project. And I have an idea for another project. Make a set of speakers similar to the old "Magnaplanar" ones that don't need "box-shaped" enclosures, resulting in speakers about as thick as a framed painting. That would be truly space-saving, and I'm sure you could figure out a way to go completely bonkers with the LED rigging!
"Turn this wasted space into something functional"
Dude...that space is functional and far from wasted. It's necessary to create good sound.
Seeing someone wearing PPE when it's probably not necessary is very relieving with so many makers not using it when it really should be used. Major kudos.
12:45 however, when grinding PBC material, you must wear a respirator (or hold your breath). You don't want those glass fibers in your lungs.
@@daveahlman1 Ever so true grasshopper.
The reason the applicator looks like a needle is because you actually push the acrylic together and use the needle to apply the Weldon to the corners. Because it's so thin, the Weldon actually seeps into the corner and spreads itself out. You can look up people build aquarium tanks :)
Underrated comment. Just think of the soldiers' lives who could be saved if we made tanks out of acrylic. It's like permanent camo...and if they can travel under water, that's even better for those sneak attacks!
As an audiophile, you don't have to have the best quality. Sometimes it's about making yourself and your setup happy. Just because I wouldn't do doesn't mean you can't.
Yep!
Too many people wast money on fancy hardware and psychological cables just to use their set up at 1/4 the power in a non treated room not even respecting speakers positionning requirements.
@@simonrano8072 Yep. The rest of us think "That sounds nice" and then just enjoy the music.
While drinking the wine that we bought with the money we saved by using ordinary mains cable to connect our speakers. 😁
Aw a semi non recovered audioperv let’s there be subjectivity, how cute!
You're not an audiophile. You made a sensible, reasonable comment. Audiophiles don't do that. Perhaps you're a recovering audiophile?
Dude's running out of desk space, dude's also having 150 inch TV on his desk.😂
It's also less than an inch thick and set at the very rear edge of my desk with a custom made mount.
I would mount that monitor to the wall.
@@photonfartsqueeze6694 yea just screw it into the windows behind it 🤯🤯
The cool thing about TH-cam instructional videos is that you can see and avoid all the mistakes made before giving it a go on your own.
And if desk space is at a premium, make panel speakers and hang them on the wall.
Part of the problem imho with videos on speaker building on youtube is that they always show the build process. And never the design process or talking about why they do something. Actually building the box is usually the easy thing to do.
I absolutely love when we make mistakes in making furniture or stuff like this, moments like this truly show how adaptable a person is, improvise, adapt, overcome🤣
I really appreciate how your content has evolved, it's nice to see you make items for yourself that you actually use. Keep it up!
Thanks man, I appreciate you being with me long enough to see the change! It sometimes gets tough finding stuff to make I actually need/want, the house is starting to get pretty full 😂
Oh dear, this is an "audiophile's" torture! Even I feel mildly infuriated, but I really enjoyed the aesthetic! The last "I'd like to incorporate more things within the speaker", tho, was the final nail in the coffin, like a stab in my chest when i thought triggering was done 🤣
Keep up the good work!❤🔥
Pretty much this. I'm not an audiophile but if we're going to take the time to build speakers we may as well do it properly. I'm still not sure why he needs to save space on a giant, empty desk.
@@alphaforce6998 well, my guess is "clean-desk aesthetic", which i Also enjoy! That said, one can use newer speaker technologies such as hard shell and mechanical bass drivers to shrink their size! Introducing lighting and other AC and/or PWM power sources within a noise-sensitive piece of equipment is generally considered a bad practice
What give me the more pain is to see the cheap rca cables used to connect the speakers ... i don't even want to see the amp.
The video is all trolling. Not just audiophiles, but really it's designed to drive mildly negative engagement from a variety of domain enthusiasts (cabinet builders, expert makers, LED lighting fans, etc.) while pretending to be maker-ey / tinker-ey enough to elicit a warm fuzzy counter argument from people with less of a clue of how they've been manipulated by the fast talk method. Most people trying CA glue the first time on acrylic are in for a bad time when it frosts splotchy and ugly, when other adhesives work. "Oh look I forgot about the crossover!" is just as fake as any other reality TV bit. It just goes on and on with trolling.
Even the initial premise is bs. People who value desk real estate put their monitors on adjustable mounts and speakers either wall mounted or on other elevated platforms, leaving the desk space clear for other uses. Heck the old school PC Hifi Logitech Z-560s had stands that pivoted into wall mounts 22 years ago and probably sound better.
@aaronb1138 I've never seen this channel before but you nailed it. It's genius really. Imagine how many algorithms this guy is in!
Something you can do with acrylic to get it fogged/frosted is using an orbital sander with a medium high grit 180-200 and going over the surface of the acrylic. This is a diy approach and can be used if you accidentally nick one of the surfaces and don’t want to restart.
Awesome project and amazing results! I made an acrylic speaker a while back and I'm still working to get rid of the rattling, glad that wasn't a problem in this build!
I absolutely love the dual purpose with the lighting as well. That thinner acrylic probably isn't the best for sound, but there are trade-offs in design. If you think they sound good, that is all that matters!
Really like that Zac doesn't edit out his mistakes along the way! It's super realistic and actually very valuable to learn from!
Those speakers look absolutely amazing. I have always loved the idea of people building their own speakers for that personal touch but this is a pair I haven't seen with lights be used like that. Very nice work.
Hi Zac! I do appreciate the Idea behind the build, as well as the quality of the work. You do however have some technical issues of varying degree.
First of all, you NEED some kind of dampening material in the cabinets, I realize that it might interfere with the lighting idea.. But there's pretty fluffy white poly filling that does the job just fine. The reason behind this is to absorb the back wave from the driver. Not doing this will result in pretty iffy resonance issues as it 'bounces' off the rear panel.
Second, A baffle that thick with a small midrange driver should have the rear of the cutout rounded or chamfered on the back side to help the driver 'breathe'. This can otherwise impact the midrange response. Depending on driver and baffle thickness, this might be an issue. It's good practice to just do it and be safe.
Third, Plexi as a material is fine actually.. Honestly most common materials are fine if it's structurally sound and thick enough, as long as it has proper bracing/support. These do not have proper support and are too thin though. So, you'll likely have resonance issues there as well. Your hardwood is fine, nothing wrong with it.
Otherwise, great job on the build and keep doing things! If you for some reason decide to do more audio things, feel free to reach out.
The number of comments on this video stating he did it wrong are baffling yours is the first I've seen with genuine advice. I have seen speaker cabinets with void space and no dampening but this space's volume and surfaces are specially designed to act as wave guides for each individual driver. This from my limited knowledge seems very complex to design around but definitely does seem to improve sound quality based on the speakers I've seen that implement them.
@@jackmarshall2496 Thank you! I try to offer sound advice and constructive criticism. I was speaking about his design mostly. But in general.. you cannot get away from some kind of damping behind the a driver covering the midrange unless it's.. open baffle or sealed back drivers. There are other creative solutions with varying degrees of success. The main thing is that the rear wave needs to be addressed, how is less important.
For speakers only covering bass, it's another story and not necessarily needed. :)
I heard you talk about this on the podcast.
It turned out really nice. I like how you integrate technology with woodworking. your channel seems to have a taste of DIY Perks with a strong focus on walnut instead of aluminium - which I like.
Walnut over everything!
@@ZacBuilds stainless for me. Aluminum for the jobs that aren't terribly needing in aesthetics. Normal steel if I'm either on a budget or doing something indoors in a dry room. House fires just aren't my thing.
I have maple floors and I regret it. 'can't trust a medium income set of renters to not damage it whenever I leave.
> Your speakers are a waste of space
> Makes same size speakers that sound worse.
The end product looks so clean. Well done
Thanks Andre!
Those look very nice and seem to be a good design.
A couple ideas: 1) you could have used heat to bend the acrylic into a squared-off-u-shape and eliminated the Weldon 2) although it would eliminate light from the top, you could have made the top wood (leaving the sides acrylic and eliminated any seams) and incorporated wireless charging pads in the top of each speaker.
with that particular glue the pieces to be glued are first moved into the final position so when the glue is introduced to the joint it spreads evenly via capillary action
Where has this guy been my whole life and how many skills does he have? The best mix of tech and DIY I didn’t know I needed.
The less you know, the happier you are. This guy is really happy.
LOL
Fantastic idea and a beautiful finished product! They look awesome!
Thank you! Cheers!
I love the space saving feature above all else in this build. Very clever, I have a similar setup with a custom made soundbar and these same Philips Hue lights and I wish we had this video a few months back, I probably would have tried integrating the lights for a big fat behind the screen defuse ambiance.
Very cool 😎 they look great
Now you're giving me ideas! I just moved and need to redo my media center. Maybe I'll try and work some LEDs into my big wide center channel.... 🤔
Now this I have to see. With an ambilight like setup built into it, it could be great 😃
I am very happy too, this speaker make inspiration for more project to the future.
another great video from one of my favorite channels! You're an inspiration Zac!
Those look amazing! I might have to make some when I upgrade my desk setup!
Get some foam circles that you put between the midrange and the cabinet when you screw it in (unless already applied to the speaker)
Great video as always Zac! Keep up the amazing work!
At first I thought based on the title that you were going to do DML type DIY speakers and wall mount them, but these are pretty cool too even if they don't exactly save any space :)
Came here for this. How is this saving space, really?
Nice looks and ideas for the future😊
Thanks for sharing
They look amazing, great idea to add the lights inside 👍🏻
I just built a desktop organizer/soudbar with 2 4" drivers and 1 5" sub. It's 7" tall, 7" deep and runs the lenght of my desk to make the speaker volumes work. It looks gorgeous since it's made from walnut.
In this exciting episode, Zac sort of plans out something awesome without planning ahead somehow, again.
I'm messing with you bro, beautiful work as always.
I love this channel man it's fun watching wood work.
Cool. Looks like it was a fun project. Thanks for the video.
That looks very nice! Would be cool if you could make the lighting inside react to the sound they are playing
They actually can! The only catch is you have to use Spotify as it's the only app that integrates with philips hue. I don't use Spotify tho :(
This was one of, if not, the best build I have watched from you! Fantastic job! All of the tools you have at your disposal is honestly a jealousy point, but oh well, lol. Not too late to print a diffuser (half moon) in clear petg and add it I would think. Great job!
18:27 "They are only 40 watts". The 'watts' don't say how loud a speaker can play. There are horn-systems out there that will provide rock-concert volume with only 20 watts or so. It's the level of efficiency that can give you a hint (a speaker with 85dB will get not the half as loud as a speaker with 95 dB when provided with the same input power). These Speakers actually turned out pretty nice. Much better than i've expected in the beginning. Well done.
I've noticed this. I had a Dali Spektor 1 and a Bill Fitzmaurice Omnitop 12 connected to the same system and I had to turn the perceived volume up 3 times as high to get the Dali to be as loud as the Omnitop 12. The Dali sounded nicer (at least without the EQ module) but small bookshelf speakers with 4" woofers will suck down power to make them loud compared to a 12" and 1" compression driver.
Those speakers are Sweeeet! Nice! Inspired to try it myself
They look awesome, great work man!
I'm in love with that workshop
You can achieve the same effect of slightly "melting" / gluing acrylic using acetone. Also super glue works quite well.
The whole thing can be solved by building supports that allow the speakers to be mounted outside of the desk
I've gotta save this video somehow because I LOVE the idea of building ambient lighting into the speakers like that :D
Zac absolutely beautiful design there. Can't wait to see more videos soon my friend. Keep up the great craftsmanship and hard work my friend. Keep making. God bless.
Thanks man! Hope you're doing well and making yourself! Cheers.
What a wonderful concept! With the frosting, it almost looks as if there is fog inside 🌫️
Beautiful design, great job!
Thanks Bailey!
I wonder if everything will go as smooth if you just bend the acrylic with heat to avoid making them miters & using the weld-on stuff. It would definitely be seamless. But then you would need to round over to match the curves of the corner bend 🤔.
I'm actually working on a portable boombox as well and ordered my BT large ammo speaker kit Friday from Parts Express. My version also includes frosted acrylic AND walnut. No bending though as I'm doing something different & do not require much
Nice! Great looking build. I’m a repeat customer of PartsExpress so I’m pretty well versed with their stuff. I think the Woofer/Tweeter placement looks fantastic on the Walnut and the lighting aspect is really great. I’m going to build a set of those too. Really nicely done.
Okay so I’m just so angry that I’m just now finding your channel cause I love tech and love wood working. And your the perfect middle ground.
For future speakers, consider using a Dayton Audio KAB amplifier with DSP. You can eliminate the passive crossovers along with the associated downsides. Each driver will get its own tuned amplifier and you can order mounting and control hardware. To save desktop space in my own setup, I bought some ART RM5 studio monitors. They are especially thin powered speakers with VESA mounting holes. I removed the stands and attached monitor arms to each, so that they are completely off the desk and positioned perfectly to the sides of my monitor.
Any recommendations about a budget-priced CNC?
Keep up the great content!
Love the build! Awesome result!! The soldering skills on the other hand... 🤣
Love the look of these speakers, they so unique wish i had them to match with my bedroom studio❤🔥
dude those are BEAUTIFUL lots of inspiration here
The cross over board you've used is similar to perfboard or solderable breadboard. Two common types are padboard and stripboard
When those lights came on >>>>>>>>>>>❤
"I'm constantly running out of desk space" says the man with a totally clean 9ft desk.
Very nice build, I plan to build some as well but my goal will be to have the face at an angle (facing a little bit up) since I'll use them as monitor stand for side monitors
Zac, from one Canadian bother to another, love your work. Keep it up.
Thanks man! I'll do my best 😃
The reason the applicator is a needle is so that you bring you seams together than run the needle along that inside corner and liquid is so thin it permeates into joint.
"I am constantly running out of desk space"
Looks to me like you have plenty. You should see my desk.
from what I recall weldon is basically a solvent that melts the plastic. it would have been easier to hold the joint together then put the adhesive in the joint. it then melts the plastic together. you cant use it in the way like you would other glues. thats why its so thin.
Good call!
All solvent welding relies on introducing precise amounts of the solvent to parts already fitted together with sufficient gap to allow capillary action to draw the solvent through the join. Then after sufficient time for softening of the surface, mild pressure is applied to force them together and as the solvent fully evaporates over time you have a fully fused 'welded' joint.
Those little 12 volt drivers are no joke. I built an entire deck with one of 'em.
Add a way to adjust the light brightness unless you did and I missed it would be nice if you could make them as bright as lamps
looks great, Dude!!
Thanks buddy :)
Those Irwin wire strippers are the bomb! I've been using them for a year or so and will never go back to stripping wires using the old-school wire strippers.
I’ve had fully acrylic subwoofer enclosures in the 90’s to early 2000’s they sounded great
Excellent piece!
One note which probably didn't impact this build - CA glue can fog acrylic.
I like the idea but I noticed some aesthetics you maybe missed. I would have channeled the mid range driver a bit further to ad a cover plate over. (Which may be in your next video for a speaker grill.) I would chamfer the three edges on the front so more elegant styling would really make the build stand out. Maybe print a signature on the back and clear coat the front and back with matte clear finish.
I built lights underneath my speaker stand (the platform where the speakers sit on) instead. Just some CCT COB led strips connected to hue with a gledopto controller. Does the job, different type of illumination though. Just a thought for people who don't want to make new speakers. Very cool idea though!
As a desktop speaker you may not get into this situation, but ideally you don’t want the sides of your speakers to vibrate. At louder volumes and at certain frequencies you my introduce distortion from the thin and low mass sides. An acrylic rod say 1” diameter could be glued in the center of the panels as side bracing to help mitigate this.
this is interesting, finally a cnc based speaker box..
If I was the one doing these, I'd have done heat-bent acrylic. Love the execution and the end result though, real good stuff.
Great results. They look expensive 🙂
If anyone wants to do DIY custom speakers keep in mind you can cut the driver holes with a router and a circle jig. It's kind of a pain but you can cut really nice accurate circles. My DIY speakers have overlapping drivers and that's how I cut them. The left and right speakers look identical.
has to be cabinet resonances with thin walls no bracing and no insulation. Creative build none the less.
Do you think a piece of foam/stuffing glued to the back port wall would help the sound a little without blocking the lighting effect? Maybe a couple of inches thick to absorb soundwaves and with the edges tapered away from the acrylic.
It would help for sure
Do you think you'll ever sell the cnc plans for this build? I would love to replicate this but instead of the acrylic panels just using some mdf.
Yes, it's 100% something I'm working on. I need to set up the infrastructure to do it and that's the main road block, but I'm in talks with a web developer.
funnily enough i scavenged speakers out of an old soundbar which had a absolutely drenched board. took this old 250watt PA system amp and ive been running the 50/60 watt 6 inch sub as a primary (hoping to find and scavange a second one with a ported box) with two small like 4 by 2 inch rectangle speakers which are about 25-30 watts each for this odd combination of deep low and decent highs. Very good work!
You could add tiny balls to increase the surface area.
Also, you want mm accuracy because it changes the sound (you can use acoustic simulation models)
clamp your parts then add the weldon to the seam, capilary action will cause it to flow into the seam.
also, squeeze your applicator bottle and a SLIGHT constant release of pressure keeps it from dripping when you turn it upside-down.
the insulator material raised the speakers a perfect amount to install some LEDs underneath!
Awesome as always man!!!
Thanks Craig! Appreciate the support brother!
Funny note on using solid stock to make boxes. I've tried it myself. One box is square, the other has twisted. So if the bases are pushed together, one if facing straight forward, the other is a few degrees to the left. Stayed sealed, so meh whatever :-)
No copyright music is the best Channel
How will the lights work when you get the dampening material in the speakers?
It looks like the only desk space you save was from putting your lights inside the speakers. In fact, it almost looks like your new speakers have the same or slightly larger footprint as the speakers you replaced.
Okay these look so good!!
Thanks for watching Soph 😘
I like the idea of incorporating desk hogging components into the speakers. However, I feel like you would benefit greatly from lifting the speakers off of the desk with some stands. I have my speakers mounted on a hacked together combination of $30 computer screen stands and speaker wall mounting brackets. It works beautifully. I can move my speakers side to side and rotate them in and out on the fly. The biggest drawbacks are that height adjustment is a complicated process, there is no way to slide the speakers forwards and back, and the speakers don't like to stay perfectly level on this stand. I need to revise this idea to make it easier to move them around and make them perfectly level. But still, I'm very happy with this solution even with the small drawbacks. My speakers are just floating above my desk, not wasting space, and I didn't have to drill holes in the wall.
Same, I have my speakers lifted onto some monitor arms (The type with the clamp and the bar that goes straight up). Now they take up no desk space plus they're at ear level.
With the goal being to save space, I thought using stands was such an obvious choice - I was so suprised when he didn't!
18:28 the speaker kind of looks like a time door from Loki. That’s fire.
While the crossover perf board was a bit oversized, by mounting the inductor coils can be mounted sideways on it's rim, about an inch of the board could be removed. The caps could likewise be mounted on end, standing up.
As to the acrylic sheets: on previous speaker that used them (Your 3D Printer is Now Obsolete), the acrylic rattled against the wood. If thicker panels were used, say 3/8 or even 1/2", there would be no obvious rattling. Another way to cease the rattle would be to use hex socket countersunk screws (black would match, brass would be cool) at two points to lock the panels down. BTW, that speaker design is more properly called a transmission line, known for complex construction but accurate sound.
I am wondering why a simple rabbet wasn't used on the front and back panels, instead of planing it down to fit the slot on the base?
I wonder what servicing them would be like considering the all glue approach to assembly. I suppose your hand could fit in where the driver comes out
