Dear folks,
this is my first post on Visaton forum. Excuse me for writing in English, my German is terrible, mostly relying on Google translate.
I believe this project is interesting in many ways so I wanted to share it with you. It was inspired by Pacto F.A.S.T. project but differs in many details. I was not happy with FR 58 driver solution because of it's inferior dinamic range and not with B 80 either because of it's price. Another full driver came to my mind, the one I used a lot in different small speakers: SC 8 N. It provides decent performance, both technical and sound wise. And is reasonably priced. Bass driver is, of course, incredible small but powerful W 130 X driver.
Since I do lot of 3D printing and produced couple of successful speaker boxes, I decided to print this more ambitious project. I redesigned two publicly available designs published on Thingiverse: Nautilus shaped shell: https:/www.thingiverse.com/thing:2398816 and pear shaped BR "box": https:/www.thingiverse.com/thing:2249300. I have increased the shell size by 4% in order to fit SC 8 N and enlarged the "pear" by 80% in X and Y axis, more in Z axis in order to get 15 liter volume and long BR tube, providing 36 Hz tuned box.
Missing here is 15 cm tall stand that raises the whole thing above the floor.
Here is the crossover:
and BoxSim simulated frequency response:
I have named the project in German in order to show my appreciation to what Visaton is providing us: great and affordable drivers and great free BoxSim software!
Hoping the real speaker will perform equally good as this prediction! Fortunately enough, I have my own test lab capable of measuring all the characteristics so I can tailor later the crossover.
I have already printed the "Nautilus shells" and stands, going to print the rest in the following couple of days.
