Cut out the first panel for the enclosures.

Only to find out that I've bought enough materials to make only one.

Default Tractrix front horn build

Here is what I have so far with my front horn. No calcs, just playing around to figure out build technique and feasibility in foam core.

Whoa, nice job xrk! I was thinking of trying something like that but am intimidated by the side cuts to get the curvature.

Thanks Carlp,
I had no idea how to do it at first. So I made the tractrix profile gauge board (the smaller piece). I cut an approximate panel and curved and glued to gauge. Then projected a 45 deg cut straight from above by eye and traced intersection with pencil. Then it still took a ittle after the fact trimming to get the two segments to line up and make a seal. Definitely make a play prototype first to learn technique. It should work though.

Default Photos of Pair of FIB's w Soundclip

Details of Flatter is Better BIB build in the Terry Cain BIB thread. I thought since it is a foam core build, better to post final pix and sound clip here though.

They sound great and have the ability to fill the room with some nice bass. I like how they ended up looking too. I just need to decorate them now.
