RE: Don I Have A Question For You.




Hey tubeguy1954,

Your questions were:

1) Have you ever used back-loaded horns?
2) Are the front horns more sonically pleasing or correct?
3) What driver/cabinet types are you using below your Oris horns?
4) Where did you get those beautiful metal stands that are holding your Oris horns & what did they cost for a pair?

#1. No, I have never used back loaded horns. The only reason for that is that I have some experience with front loaded horns, and I have found them to be easy to understand and sonically pleasing in many ways. Other than that I have a half baked theory that back loaded horns could cause some timing or phase problems as a result of the delay of the back wave in relation to the front wave because of the time it takes the back wave to travel the length of the horn before being emitted. I don't know if this theory has any validity or not.

#2. Having no experience with back loaded horns I am not qualified to say.

#3. Below the Oris/AER I am using a Bill Fitzmaurice designed HT Tuba folded corner horn subwoofers driven by Dayton Audio RSS390HF-4 15" Reference HF Subwoofer 4 Ohm. The crossover is nominally 160Hz with high pass and low pass slopes of 96dB/octave accomplished with a DEQX HDP-3. The DEQX also allows the AER drivers and Dayton subwoofer drivers to be time aligned as though the acoustic centers of the drivers were within less than 1/8" of each other instead of the 16+ ft. that actually physically separate them. I am very pleased with the HT Tuba subs, but I do not know if I would be as pleased with running them up to 160Hz if I were using crossovers with more typical 18 or 24dB/octave slopes.

#4. If you are referring to the black powder coated aluminum rods and bands which directly support the Oris horns that is a product sold by BD Design, the source of the Oris horns. I don't remember the price. If instead you are referring to the entire wood, brass and aluminum stands they are something I designed and made for myself. The truncated pyramid box on the bottom is filled with sand as part of a vibration dampening system I invented. With the exception of threaded fasteners all of the brass parts were made from scrap brass I picked up at a scrap metal yard. My visual paradigm for the stands was movie maker's or book illustrator's concepts of Victorian or Edwardian era science fiction apparatus such as H.G. Wells time machine or devices aboard Captain Nemo's Nautilus. A member of this asylum has since taught me that style is now called steam punk.

Thank you very much for the compliment.

The picture below will perhaps help the above text be more understandable.

I dream of an America where a chicken can cross the road without having it's motives questioned.
