"Not myth. Fact. Put the driver in what we recommend and see how much power you can run on it before it reaches Xmax limits. Power handling is not only by Xmax limits. You can thermal a coil without it getting anywhere near Xmax limits with enough power. Again, for what our customers do to our subwoofers we have our recommended enclosures. And again, you can do whatever you want to. Our warranty extends to rated power and covers manufacturers defects, not abuse and/or large enclosures. I know many people (some are friends of mine) who run MUCH larger enclosures than what we recommend with very good results. They also know that if they cook the woofer it is their fault and not under warranty."
"Is Marty box a big risk ?"
maybe he is just tired, but the post is completely backwards in reasoning.
a larger enclosure is *more efficient* than a small enclosure, so the driver requires *less* power for any given spl.
in a large enclosure the voice coil will travel more for a given power as well, which provides greater cooling.
there is *less* risk of cooking a driver in a large enclosure because you don't need to apply a big eq to bring up the bottom end as you would typically do with a small sealed enclosure.
as we take it to mean, the elusive hoffman's iron law states that efficiency, extension, and size of a subwoofer are interrelated such that if you want a sub that play deep, and does so efficiently, it must be large. that is why the marty is large. because there was no compromise made to extension or sensitivity.
