I have reprinted a lot of the horn in the uv filament and made a small spacer for the mids.
I redesigned the base and siliconed it all together.
It sounds much nicer and can go a lot louder without distorting. I also managed to get people to carry the relatively delicate horn into a squat in Manchester without breaking it haha Had a lot of compliments around how it sounds spacer: |

I did some measuring of this and the mid only went down to 500hz rather than 350hz I think I have made the rear chamber for the mid drivers too small, going to redesign them and make them a bit larger to see what happens.
I also think I have got the mid drivers a bit too close to the baffle, I am going to make the front chamber a bit bigger as well. I measured this in my living room so definitely needs taking with a pinch of salt

For 3D printing i would recommend CNC-Speedform AG in germany.
They have very very cheap and fast delivery 3D prints in SLS. https://www.cnc-ag.de/nl/ If you want to print cheap in SLA i can recommend VRT Proto in Netherlands http://www.vrt.nl/

[QUOTE = imortal] Finalmente terminei o protótipo
Parte dela está colada com fita adesiva porque eu não coloquei todos os parafusos e quebrei parte haha. [/CITAR]
Todos funcionam a partir de 12v. Vou refazer a fiação e colocar em algo haha Vou mover as portas de baixo mais para a borda, isso foi o mais próximo que eu poderia chegar com elas sendo um cÃrculo. Eu irei com eles sendo um slot ou triângulo. Eu potencialmente tentarei tornar as portas intermediárias maiores também, depois de fazer algumas medições. Minha interface de áudio quebrou, então está atualmente com a Thomann, então não posso fazer nenhuma medição até que eu a tenha de volta, infelizmente. Good night, could you help me to develop a SH? |

I have finally finished the prototype
Some of it is taped together because I didn't put all the bolts in and snapped part of it haha.
All run from 12v. I will redo the wiring and put it in something haha I am going to move the bass ports more towards the edge, this was as close as I could get with them being a circle. I will either go with them being a slot or triangle. I will potentially try making the mid ports larger as well after taking some measurements. My audio interface broke so is currently with Thomann so can't take any measurements until I get it back unfortunately. |

it's supposed to have a dip - helps filter out harmonic distortion. maybe make your bass taps a bit smaller and have them as close the corners as possible. mid taps possibly too small.
