Default Dynamic Power rating ???

Back in the 70's and earlier the manufacturers made some hefty power claims. Peak music power is one that comes to mind.

Well it is refreshing to see that a Canadian firm has resorted to using the term "Dynamic Power" in their advertisements of their somewhat overpriced under engineered product. What we won't resort to to sell the "goods"

Its just plain amazing to me that their 25 watt tube amplifier sounds as good if not better than someone elses 40 watt amplifier because of its Dynamic power capability.

If I'm not mistaken the FTC put the hold on the hot buzz words and claims of the 70's here in the states. Its too bad the Canadian government doesn't watch the claims by its manufacturers.

I realize this is about woofers but...

Quote from Klipsch:

"Dynamic power indicates the actual power this amplifier will deliver to the woofer under normal operating conditions. While the FTC power rating indicates power available on a continuous, long-term basis, subwoofers do not rely on that type of power. Instead, the amplifier is called upon to deliver large, short-term peaks of power to be able to support the wide dynamics required by today's digital music and movie formats. In addition to the required FTC power rating, we've provided the dynamic power rating as a better indication of the product's true performance."

FTC Rated Power: 105 watts continuous,
22-100Hz @ = 1% THD
Dynamic Power*: 440 watts @ = 1% THD

Gotta love that dynamic power.

the wide dynamics required by today's digital music and movie formats.
what's different between that and dynamic range of yesteryear?

That sounds more like Klipsch feeling the need to jump on the power means all bandwagon that only seems significant to the illiterate that chase big numbers instead of quality sound.
