What causes this vibration is the movement of the speaker cone causing compression and rarification(sp?) in the air around it. Round cones give a relatively equal movement of air from all points of the cone. Because 6x9's have the oval shape, the outside edges that have less surface area move smaller amounts of air than the inner area with larger surface area. The difference in the sound waves that project from the different areas cause acoustical issues.</p></blockquote><p></p>
