The Klipsch sub that was mentioned has 650w with an amplifier that is capable of 2400w bursts. This is equivalent to quoting max power.
It's interesting that Klipsch says that their 15" sub with a 15" PR has more surface area than a 21" conventional subwoofer.
In reply to:
The RSW-15 surpasses the performance of a conventional 21" single-driver subwoofer through intelligent engineering. Pairing a heart-throbbing 15" rear-firing Cerametallicā?¢ active driver with a 3-inch voice coil and 30-pound motor assembly with a 15" front-firing passive radiator gives you more surface area than a 21" subwoofer in a much smaller footprint.
It almost seams like they think that a PR should count as an active radiating surface rather than a resonator. This would be equivalent to counting port area to driver size. I am ashamed of Klipsch for such blatant misinformation.
