Default My Single Fostex dual horn loaded design.

As soon as I get around to it I want to try out this design I came up with. The driver is a single Fostex 103EN. Will update if I go for it.

I still don't understand the design. Where does the driver go and where is the mouth or where are the mouths?

I'm guessing the high sound comes out at the front, due to the deflector in the corner and the bass comes out the bottom?

Hi there c: The dotted lines and solid lines do not seem to have the same meaning in the construction as in the drawing, so we can not see where you are heading in the next construction step. Will the large triangle on the right side, be dead space or connected somewhere as a resonant chamber? ...regards,Michael.

At this point it's a dead space chamber...... The front of the fostex will fire to the right and hit the 45 degree angle and shoot outwards from the top right corner of the design. The rear of the speaker will fire to the left hit the 45 degree board exit from under the front board and travel down the front baffle which is like a 3 sided horn. The dashed lines are hidden surfaces under the front board. I still need to cut the throat triangles and still mulling over what they should look like. They will be removable so I can try multiple different throat designs. My other vision is two fostexs magnet to magnet with the rear of them venting into the dead space chamber and the fronts firing to the left and right.

The whole reason for this design was to up the efficiency of the fostex by horn loading it, and also to combine the front and rear wave of the driver into the same space at the same time.

This is where I'm at now.

Ok I see now - the driver is mounted in top right corner on large panel and edges are sides. Should never waste space in a horn box - fold as needed to get more length as length = more bass gain.

Small taper magnifies bass, sharp taper magnifies highs, medium taper magnifies mid range. And yes I know length = more bass. that's why this design couples directly to the floor.
