Acoustic Loading Optimized Final Generation Horns – ALOV2

Most readers of my blog should already be familiar with the special optimization technique for my acoustic loading horns which I have called Acoustic Loading Optimized (ALO) horns. The main focus is to get very good acoustic loading horns together with excellent and even directivity control. Almost all horns that are based solely on acoustic loading optimized profile fail in this regard because they more or less strongly focus the sound toward high frequencies.

Over the past years, I have learned a lot about acoustic horns and have continuously developed and significantly improved my inventions in this field. The results are my final generation acoustic horns, which I will be presenting in detail in the near future. The first step is the presentation of the improvement of the ALO procedure to ALOV2.

The Mysterious World of the Karlson Tube – Part II

In the first article about the original Kalrson tube, I was able to develop the BEM models and investigate the acoustic properties of this special type of horn/waveguide. I made no secret of the fact that I particularly disliked the directivity control. A few days ago, I had an exciting idea about how to modify the Karlson tube to achieve better results. The implementation wasn’t that complicated, and in the end I was quite surprised at how good the results were.
