It´s time to post my newest work. I built a pair of Loudspeakers with a high WAF ( wife acceptance factor , best: very small, no cost and very good sound) ;-) , for my dining room. So i took a 3,5 inch high end speaker and built a transmissionline box from 3/4 inch MDF. The camfer is 1/2 inch 30 degree for a better omnidirectional angle. The Box is about 35 inches high, 6,5 inches wide and 9 inch deep. The veneer is caucasian walnut burl, the lighter stripe is poplar burl and the back side is french quiltet figured walnut. I couldnt decide what bookmatch was nicer, so i build 1 box left and 1 right bookmatched. It´s the same veneer what i used for my cabinet restauration. To work with this poplar veneer was very difficult, because after the press it was very flat and straight but when i aplied the glue, it warped like wild. So i have a few cracks in, what i had to fill. The finish is just a few layers of shellac. Everybody who hears this small speakers is amazed how good they sound and what a good bass they have.

The speaker is a Visaton B80 ( a German loudspeaker company). The Transmisionline is a specially calculated folded horn inside the box wich goes in this case from big to small to the opening. I have the sources and plans (but in german) and can email them, if anybody want them.

These look really nice! Are there grills for the speakers? Are you concerned about them getting damaged?

No there are no grills, because they influence the sound in a bad way. My kids are 2,5 and 6 and it is JUST a thing of education.!!!!!! Thats why the speakers are flush mounted with the surface and the camfer is important.

I’ve built many speaker systems and the simplest design usually sound the best (not that your design was simple from a woodworking standpoint). That’s some very impressive work!!!

What driver did you use?
