3D printed Speakers

Those speakers are amazing aren't they?!

I don't seen any issue in modifying them to work with another device though. I'm surprised there's so little discussion on these, Matt's really excelled himself on these.

The tutorial is great! I love EVERY video MAtt is producing.

Now I am really thinking of building a set of those. Has anyone already bought their pack? I wanna know how large the largest 3D files are for printing, as they look very big. My printable surface is 220x220x270 and I wanna know if I am able to print them myself.

These look amazing! And such a great tutorial. 

I want to go through with the build but I'm wondering if there is a way to drive these speakers with my built-in amp on my Denon AVR. I don't have pre-outs so building these with a built-in amp means I won't be able to drive them with my current set-up. I need a way to find a way to make them passive and build a crossover I think.

Does anyone have any ideas?

Matt has tuned them specifically using a DSP so a passive XOver won't work (well) nor likely fit in the limited space.

Back in the dark ages, I used to connect speaker outputs to Line inputs as the impedance is much higher so it's unlikely to break something. Or you could just put a small "dummy load" of about 16R across each speaker port and tap direct from that (in parallel) but be careful you make don't push the volume too high as or the dummy loads will generate magic smoke.

Hi all!

I downloaded the instructions for the speaker, but no words about the printing settings. Can anyone tell me them? 0.2mm or better? Any good advice for the tall objects?

Thank you very much!

I'm assuming PLA here but the plastic isn't entirely structural so 0.4mm should be fine. A larger bead and a slightly larger nozzle might help to as you're looking for something that will hold while the main bonding agent (the plaster/PVA mix) goes off. That's what gives these beasties their heft and finish isn't that important if you're applying veneer.

Best of luck, these are amazing from what I've heard. 

@marcdraco thank you very much!

also, can you help me with one more thing? How much plaster needed to how much pva mixture? What ratio is the water-pva mixture? 
 
thanks forwardly!

Hi @fankyzene!

I would also go with the advice from @marcdraco. I would recommend a rough fast print, since it is only providing a shell for the plaster and the outside will be sanded/covered anyway.

May I ask of you to check the STL files on how big they are in dimension? Will they fit on a Printarea of 22x22x27? Thanks!

Hi @photofreak126, Matt's machine looks like a common-or-garden Prusa the same plate size as (say) the Ender 3s and many other "budget" but not space-saver designs.

Matt tends to keep his designs within the budget of most hobbyists as opposed to some people I won't mention who assume that even people like me keep FLIR cameras just hanging around.

A FLIR is great for some repairs but I find a finger or even a nose is enough to detect localised overheating and the FLIRs are really only useful in very specific situations.

Hello! I bought your project and I'm going to repeat the speakers, could you post the speaker connection diagram of the ADAU board and the amplifier?

Hi. I also bought the project. I ordered all the parts, except for the Tang Band W3-1364SA. It is no longer available for sale. What else should I choose? I would not like to create the DSP configuration myself (I do not have that much time to learn it).

Edit / I bought Tang Band W3-2141

Good afternoon I printed and assembled the speakers completely as in the video, I made speakers with a tweeter, flashed them and turned on test songs, there is a rattling sound from the tweeter on some songs :((What can be done to remove them? Matt's firmware without tweeters works well, but taking into account that that in this case nothing is output to the tweeter at all!
