1) T/S params are the only way we have to closely predict the way a driver will react in a given situation. My problem is the standard of 1w/1m. How linear does the response stay at half or even full power? Most of us don't just run at 1w. 2) I was looking at the response graph between an Eminence delta12lf (56oz mag ,BL 14.1) and an Eminence omega pro12 (109oz mag and BL of 17.4) . The delta has a stronger bottom on the plot, I was thinking (correct me if im wrong) that the delta having the weaker mag and having less control over cone motion is what allows it to have a better response at low power on bottom but this is at 1w/1m. I would think that at some point the input power would "overpower" the magnets power to retain a linear response and I would think that it would not take much power to accomplish this as the mag is only 56oz. On the other hand the omega pro with a 109oz mag at 1w/1m the 1 watt would not be enough to generate enough power to put the cone into motion because of the heavy mag yielding a less than desirable plot. But at x amount of power that same mag would have much better control over the cone and things would heat up and "loosen up" actually yielding a better response than the delta 12 but only in a certain power range. Is this off base? 3) I realize that some of this also pertains to sensitivity and how it is derived. I was just thinking that a driver could specifically built to look good at the industry standard of 1w/1m when in reality that same driver under 1/4-1/2 power will have lost all control and that plot that looked really good has now gone to crap with the driver under load. 4) Do you find it hard to deal with that most pa's put out less bottom than your rig?
