TWEETERS are optional, as the midtone driver + DSP sounds great on its own, but for the best quality a good budget tweeter is the SB Acoustics SB26STCN, which is my favourite overall due to its pricing, but a premium option is a Scanspeak D2608/913000 Tweeter. It has a bit more ‘sparkle’ and refinement, but this will ONLY be appreciated if the final speakers are given a signal from a high-quality output source like a dedicated DAC.
If you want to print the baffles, the recommended magnet size is 10mm diameter round neodymium magnets, with 5mm depth maximum.
Fixtures and fittings:
40pcs M3 threaded inserts (for the speaker drivers)
40pcs 3mm x 8mm countersunk m3 black screws (for the speaker drivers)
200pcs Self-tapping 2mm diameter screws, 10mm length max (build platform screws)
24pcs 3mm diameter self-tapping screws (amplifier screws, DSP chamber, midtone chamber base)
2x step-down voltage regulators, 5v output (for powering the DSP and fan)
2x 1000uf capacitor (add across the output of the regulator to reduce interference)
2x Power Adapters (100w ideally, each. A low cost option is old laptop power adapters)
1x roll of 16awg wire
Recommended glue is CT1 - it sticks to PLA well enough and doesn't set too quickly allowing the whole speaker to be screwed together before it begins to dry. This allows any spill over to be wiped away (use an old brush to get inside the air guide etc). Sets with some amout of flexibility. Readily availabe in the UK but not sure about equivalents for other territories. Visit the Forum or Discord server to see what the community recommends for each region.
SAFETY NOTES ON PLASTER OF PARIS: If you're stupid with it, it can be dangerous. NEVER put your hands/feet/whatever into plaster of paris EVER. It can suddenly set without warning, creating a lot of heat in the center, so you'll get burned or worse. Because of this never leave a batch of wet plaster of paris in reach of children or pets. Wearing a mask is recommended to not breathe in any dust, and goggles to stop it splashing into your eyes. Stay safe people!

It basically explains the design most companies go through to put out a product nowadays, but you can do your own at home if you have the time, skill and patience. Remember, the fact that you can customize your DSP means you can give it a different sound profile if you choose something else than flat. You could also slightly tweak things around to be able to fit other amps (within reason), meaning you could have the perfect speakers to last a really long time. Absolutely incredible.

It's the best case to do it like that if you want the amp not changing anything unexpected on the frequency band. Every amp acts kinda differently, and could end up with peaks and dips in the freq band. If you match the amp directly to the speaker and calibrate it at the end of the production steps, you make sure each of them sounds almost the same. you always have slighty difference with 2 speakers, if you dont buy matched pairs and even these matched pairs are not performing 100% the same, but as close as it is technically possible.

Wow. I am an engineer and have designed and built speakers using exactly the same tools that you have. I gave up on 3D printed enclosures though - did not think of the plaster of Paris method. So I used stacked plywood layers. Great idea. If I were to do something similar I would probably replace the two subwoofers with a single larger unit. Of course this would increase the footprint but reduce height. Probably no need for separate tweeter either with your choice of midrange (but I am old now and cannot hear high frequencies). Excellent and thorough design though - way more professional than anything else I have seen on youtube.

[@Fowly]

As an acoustic engineer, I must say that it is very impressive. The magnitude response is fantastic for the size ! I'd love to have those for my TV. Also, doing a three-way design by adding the tweeter isn't just for high frequency extension, it also yields better directivity. When the wavelength of a sound becomes bigger than the driver, it becomes omnidirectional. It makes the off-axis magnitude response quite inconsistent, which is bad because it can be heard from the reflections of the room. A three-way design minimizes that, so it has a superior soundstage !

[@erkkijaakkopetteri]

Being omnidirectional is not a bad thing and has nothing to do with adding a tweeter anyway - adding a tweeter does the opposite thing, preventing the larger full-range driver from beaming in higher frequencies. The bad thing is that it adds lobing and the driver spacing here looks particularly poor in that regard. A speaker being three-way is not intrinsically better in off-axis response, the main benefit compared to two-ways is decreased intermodulation distortion.

[@Fowly]

@@erkkijaakkopetteri I didn't say omnidirectional is bad, I said that if it is the case at some frequencies and not others, it will create an off-axis magnitude response that is different from the on-axis, thus making the soundstage wrong. I think that the driver spacing is fine here. This is a very slim enclosure where waveguides are out of the equation, so the vertical directivity will be poor no matter what, even with more optimized driver spacing. Plus, having the midrange driver at the top is a classic trick to lower the minimum listening distance. Because it is a relatively near-field listening setup, intermodulation distortion should not be a problem here if the drivers are half decent. Eventhough it's quite audible in test tones, it's actually very difficult to pick up when listening to music. Frequency response and directivity are by far the priority, so the more consistent dispersion of a three-way system is its main benefit in this scenario, especially without any waveguide.

[@erkkijaakkopetteri]

@@Fowly I mean, almost all speakers are omni at lowest frequencies and more directional at higher frequencies. It's not a problem and a speaker being three-way does nothing to solve what you're describing anyway. The enclosure being horizontally slim has little to do with the vertical directivity, that's no excuse for the driver spacing. Yes, mid at the top is good, but the spacing between the tweeter and the mid is objectively awful. IMD is definitely a problem in many two-way designs, near-field or not. It might be difficult to intentionally pick up but it is a significant thing. I agree that FR and directivity are more important, but once again, the speaker being three-way offers no fundamental improvement to directivity unless the two-way comparison is fundamentally flawed to begin with.

[@Fowly]

@@erkkijaakkopetteri Mid-drivers and tweeters also become omnidirectionnal in their lower frequencies, the effect is just lessened because of the baffle absorption. But, it is definitely a problem in crticical dispersion angles in the 45° to 90° range. A slim enclosure like that doesn't allow waveguides to be used. So, a three-way system helps a lot in that regard. I understand what you mean for the driver spacing, but I don't think that it would make an audible difference. Maybe the sweetspot could be closer, but regarding vertical dispersion, it will be poor no matter what. So if we're going for more precize optimizations like that, what should make an actual audible difference would be to put absorption panels on the ceiling 😅 And yes maybe IMD/MTD could be an actual audible artifact but in my experience, if the drivers are half decent, you really have to play the speaker very loud to hear it. Maybe loudness was priority for this project, it wasn't mentionned anyway.

[@erkkijaakkopetteri]

@@Fowly I think I see your point now, but can't agree. The TB subs require crossing low enough that the transition to the fullrange speaker is basically omni and thus smooth. Adding the tweeter makes things worse when it comes to a smooth directivity. In any case, if the tweeter flange plate was removed, it could be placed a lot closer to the mid, significantly reducing lobing.

This is insane! I came into this video expecting expensive tools and laser/waterjet cut wood, metals, and acrylics. Im shocked you made something that looks so traditionally crafted so easily and efficiently. All the prototyping that went into refining the design is very apparent.

[@TheCrash1983]

fuck yeah

[@buka9330]

Impressive design, however I encourage you to try using coaxial speakers (as a mid and high drivers). When sitting up close to the speakers it is important that the mid driver and the tweeter are aligned in phase at all listening positions. That requires the drivers to be as close to eachother as possible. Doing that will make the listening sweet spot larger. You could also try to put the tweeter and the mid driver in a single waveguide/horn. Or use a tweeter that can be crossed-over at lower frequencies, like the SB26ADC. Also^2 take a look at "constant directivity speakers". It's something Im trying to learn and build now. Hope that helped You, or whoever else who reads this.

[@lukebetterton]

Does having the drivers vertically separated rather than horizontally separated mean that the listening sweet spot is only being restricted vertically? So for example, if you were sat on the floor below the speakers they'd probably sound bad but if you're sat around the same height as them then you're probably fine anywhere in the room?

[@buka9330]

@@lukebetterton From my understanding, yes. If you keep your head level you could move left or right and still be in the sweet spot.

[@JxH]

Dipole Ribbon Tweeters were the best I've heard so far. Ultra realistic sound, like being there.

[@Fowly]

There's no way to achieve a magnitude response as good as that with a coaxial design in such a slim enclosure. Sure, the soundstage will be better, but the low end extension will be significantly lessened.

[@buka9330]

​@@Fowly My point is to keep the tang band subwoofers as they are but change the midrange driver and the tweeter for a coaxial woofer. My reasoning here is since bass sound waves are really long, few centimeters of distance between drivers won't really hurt the off-axis magnitude response in the bass region. (1/2 wave of 200Hz is 85cm in length)

Many printing enthusiasts these days have much larger printers, ( and I'm guessing you do as well ) so it is very thoughtful of you to focus on an entry level size machine to enable the largest possible audience to benefit. Your engineering skills are top shelf, and your attention to aesthetics as well is to be lauded. I'm just about to start printing a set of large floor-standing units I designed for my Modix Big60, with 10mm walls.

I used to make speaker boxes in the 80s using similar techniques with an equation, calculator, wood, saws, ports, filament, etc. I find this evolution and your video quite satisfying. Kudos to you sir, great video!

[@MEatRHIT2009]

I've made my own speakers and the only "complaint" I have here is the whole being astonished by 35Hz. It's impressive for a 3" driver for sure but you can easily get that in a good 5-6" midrange in a basic bass reflex box. I have two pairs of bookshelf speakers that dig into the 30s one with the Aurum Cantus AC-130MKII which by volume is probably actually smaller than this box though a bigger footprint, the other is a behemoth though with a ~7" Adire audio extremis 6.8 and that one I think hits upper 20s with good placement. Really cool design and video though.

Liquid putty or rubber or any other manner of viscous/thick setting liquids would probably work better than plaster for the chamber, essentially eliminating all ringing as it will be completely dead due to the energy absorbtion of the putty. Something that stays relatively plyable/liquid and sealing it in is how most speaker designers are doing "mass tuned damping" now. The mass of the rubber layer, along with its viscosity and resistance to energy transfer makes it perfect to eliminate ringing. It's how I made my huge subwoofer cabinets. Every panel is 2 layers thick, lined between with green goo and on the outer side with heavy rubber. No cabinet noise, even with huge 4 foot+ panel sections.

Would be really nice to see a passive crossover build for these. Many of us already have nice amps or home theater recievers that would drive a pair of these easily.
