[QUOTE="hispls, post: 8403053, member: 614752"] There's plenty of people who will buy the "best" just for the sake of having "the best" and pricetag is not an issue or the higher the better to make them feel elite. When your build is hitting 170's most of those are 4 or fewer drivers and the subs are a small portion of the cost even if they were 4500$ a whack. Look at the price of Critical Mass equipment... there's also a company that sells 1000$ RCA cables and 100$ a foot speaker wire. There's a company that sells 8$ ice cubes. 4" coil is not needed for thermal reasons for 3 second burps period. There's guys running 40KW worth of amps to the '05 Shocker Sig and the failures were only outgassing in the coils (which was fixed by a thicker former). Even in those applications 3" coil (and a thin one at that) is adequate for holding a 3 second tone. As far as "gaining" from larger ceramic motors it is very marginal going larger than what has already been out there. The only purpose of 4" coils IMO is to stroke the ego of the people using them so that they can run more power for the sake of running more power. All things being equal you lose efficiency making the coil larger and the gap wider to accommodate coils that'll hold 3KW continuous power and you wind up in a scenario where it just takes you twice as much power to get to the same output... but you can brag about how much power you run. Any big-boy subwoofer should have a big impedance spike. This is not dependent on magnet materials. How many subs have you run impedance sweep graphs on? Your use of the term "power compression" makes no sense here either, care to elaborate? [/QUOTE]
