Post Subject: Mid bass horn.Posted by Bill on: 4/26/2010

The actual first reflection of my horn is not from the side wall or floor but from the back wall. The horn is actually against the side wall and floor which gives it the configuration of a quarter horn with the side wall and floor acting as an extension of the horn itself, thus no first reflection. This allows the horn to reach deeper for its actual length and mouth, while cutting off the two most damaging first reflections. The back walls are lined with RPG diffusers which also have built-in absorption down to about 100 Hz., thus partially removing this reflection also. Directly over my head is a cage for an Electrohome 9500 LC projector with sound absorbing material which also mitigates the first reflection from the ceiling. Thus there shouldn't be much of a bounce wave compared to the direct sound for the listener.
