It is not a secret the using a number of decoupling mechanisms between driver and baffle it is possible to change sound in resonance or amplitude department. However, if you guys insist that the tightening and loosening the screw has PHASE effects then let look at the problem deeper. If you remember in Macondo I use a positioning table with .01mm precision to position my MF channel.
I do insist that it make a big difference BUT I also insist that the axis must be paralleled. I presume that when we tightening or loosening a screw then we inflict a microscopic angling of the driver’s axis. This does nothing else then set driver very precisely in or out of time aliment. However, this super exact setting is applicable only for a signal point in space. This way I always advocate to keep the axis as parallel as possible and to use high calibration driver excursion positioning mechanisms, instead of the axis angling. I was taking about it many times, the picture below indicate the problems.
