I agree with the last poster that the SPEED of mechanical vibration EVACUATION is an important issue. I also agree that the MATERIAL used for the cone is important. I also would add that the SHAPE of the cone is important. When one employs proficient VIBRATION ISOLATION in the system A PRIORI it’s much easier to differentiate among all of the myriad types of cones, footers, and all the various materials and shapes of CONES. In the interest of saving everyone a lot of time and effort and expense I offer the following ranking for a number of audio cones, in DESCENDING order of sound improvement. For the experimental among you try cones points up or two cones points down and one or two cones points up. This experiment should illustrate the diode nature of cones.
