Ported power handling

Is it true that the power handle of a sub in a correctly built ported box (above the port tuning frequency) will handle more power than a sealed enclosure above these same frequencies for the same sub (lets just say 22hz tunning frequency for giggles)???

Power handeling for subs is lower in ported enclosures. Power handeling is higher in sealed boxes.

Actually, both thermal and mechanical power handling is higher with a ported box. The reason ported is recommended when using lower power is simply because it is more efficient. At any point above tuning, a ported box will have more cone control than a sealed box, equalling less excursion and also having less distortion than a sealed box. The tuned frequency is the point of highest mechanical power handling, and excursion is kept to a minimum even though SPL rises at that frequency. That's the reason SPL competitors apply 10,000+ watts to a sub at tuning and get tons of SPL, with a sealed box and that much power you'd blow the cones straight out of the subs. Thermal power handling is higher with a ported box, too, since air is allowed to move in and out of the box, it helps keep the voice coil cooler.

Jeese I was off. Thanks Jon. I always thought power handeling was higher with sealed. I guess nobody explained it to me. Sorry for the crappy answer Brian.
