[QUOTE="THATpurpleKUSH, post: 8731933, member: 615398"] This is a factually incorrect and complete ignorant statement. When a driver's suspension loosens after break in, an inherent effect of the suspension softening is in fact a drop in fs. The amount that fs changes depends on the driver and materials used to build it. This change can be further backed up with equipment that can measure tsp data like the Klippel or Dayton DATS system by completing a before and after measurement of ts parameters. That being said, manufacturer listed tsp data is rarely accurate and often manipulated by the manufacturer's marketing department. Often listed specs are an average from the production run. The only true way to know is by physically measuring the data with a Klippel, DATS or other reputable accurate method. edit: further example using a Blaupunkt GBW801 pre break on the left and post break in on the right. Break in consisted of playing 25hz free air on roughly 25% power handling for 10 mins. Note the roughly 14% drop in fs after break in, I still wouldn't call the #'s 100% accurate due to the vas measuring method needed for the DATSv2 but there's enough data there that I would call close enough to make analysis.
