Oblate spheroid 3D printed near field speaker

[arunvenkats]

Hi Folks,

I am building a 3D printed oblate spheroid desktop speaker for a 3" full range driver (Fountek FE85 3"). Based on Thiele parameters, the design is a 1.9L ported system. Would love to hear feedback and suggestions before I commit to the print. That's a long 1 day 12 hours print per speaker! The goal is to have a high quality near field speaker for low and medium volume listening. Need very good mid and highs. Good bass (only 3") is a plus which I hope to get through the ported design.

Some background: I recently built a proper 3 way system (with MDF) from scratch and I was very happy with it. It had exceeded all my expectations. I have a 3D printer and I wanted to experiment with builds which could only be done with 3D printing and hoping to get a really good desktop, near-field listening pair. My first choice was to build a spiral transmission line speaker but I could not find any 1"or 2" drivers here. Anything bigger, my printer won't accommodate the size. So I moved on to try a teardrop speaker. But again for a 3" speaker the size was uncomfortable. Ended up trying to build an oblate spheroid speaker now.

Arun

Looks lovely . For ideas on installtion or isolation, do check out the Eclipse TD series speakers.

You can look for used/old harman kardon soundsticks which are having very good 1" line array drivers or Bose tiny cubes and reuse the drivers for experiment if they found suitable...
