Another iPhone horn speaker

Folded horn design. Effective horn length of around 16"-17". Print in two pieces, so, no support material is needed. The side piece is offset out 0.0025" in the grooves to accept the main piece. Use medium CA glue and clamp the two pieces together.

The pocket for the iPhone is huge ( 0.5" x 3.37"). Soft foam pieces can be put there to make better seal.

The sound is not bad. Better lows and not so bright. Good enough for me.

Have fun.
