Hi Wayne,

I've been thinking about your corner horn design, and the
one thing that's been bugging me is that as designed, the sound
waves are being focused into a corner, then reflecting past each
other to be sent into the room around the sides of the cabinet.
Can you comment on placing a wedge in the corner as a reflector?

I've attempted a top view ascii version below. Assume everything
is at 45/90 degrees and the point of the wedge would be against
the baffle board.

Thx, Chris

OK, so the ascii art and html aren't compatable... hrumph.
It looked good in my xterm. :^)

What you have to do is hard-code all of the spacing. Or include a line-art drawing of your idea. I suggest GIMP.

Put the image file somewhere that Apache can find it, and stick it in your post.

Peace,

Maybe this will work better...

This wedge is a good idea, but surprisingly, you'll find that it doesn't make a noticeable difference. I used this exact sort of reflector in early prototypes and for the same reason you suggested - It would appear to direct on-axis sounds better. But I found no difference when I installed such a wedge.

Check out John Sheerin's wave mapping animation. It shows the movement of a wavefront past reflectors such as these.
