In the Thread: Phase plug for midbass
Post Subject: Radiation pattern, midbass?Posted by ulf on: 11/10/2006
Here is an image depicting the radiation pattern of the HF for a midbass with and without phase plug. The dotted line represents the HF output. This is not a measured response!
Here are a couple of pictures that may be amuzing. My girlfriend and the second pair of the horns in the first picture and the moulds in the second.
The horns are made of a mix of conctrete and steel fibres.
I said that they were tractrix which as you can see is not entirely true. Tractrixy would be better. They follow the tractrix equation with regard to area and length ratio but since they are rectangular it will not be a real tractrix. The rectangular shape was choosen to make them mate better to the floor.
Unfortunately my horns are still out in the garden. I need to do some renovation to the house before I can take them inside.
The first pair however is installed at my friends house and sounds amazing.
