Post Subject: The Ooopsiness in upperbass hornPosted by Romy the Cat on: 11/2/2007
Very cool, James, it would be very interesting if you put your ears into an investigation of “Ooopsy back chamber.” I was wondering about the A45 Lowther as well. The 125Hz midbass horns that you made, how big the input hole in there? The attempt to make the “Ooopsy back chamber” is very noble idea and I do not know a lot of people who did anything in this direction. After spending my unsuccessful efforts on the subject and come to a feeling that we should not necessarily should apply the algorithms and rules of musical instruments building (which I do not know personally) to the audio building. The Ooopy sound of string interments and the Ooopy sound of loudspeakers might derive from different means. I personally tend to feel at this point that Ooopsiness in loudspeakers is more upon the resonates of cones then upon it’s environment. The environment juts dumps the cones, still a cone should be able to crate the Ooopys… that the environment might embrace… Go figure…
Generally, as I discover recently the combination of back chamber attaching on a drive and increasing the damping factor from amps doe very-very well. Still, it is how my particular driver reacts to the things and other drivers might do different. I do not know what your Precision Devices PR107 is all about, can you post the data file? Also, one more thing. If you dive into the hunt for “Ooopsy back chamber” then try to listening your British Tannoy Red from 1960s. They do have some extremely interesting Ooopsiness that you might find worth to mimic with your upperbass horn.
