Read and understand specifications of speakers. Usually most low-frquency transducers can handle 25% of the nominal power in long term (for minutes) For example : 1200W AES & 2400W Peak means: average maximum power of: 300W However if you reach that 300W average the lifetime likely will drop seriously. Otherwise the testing methods defined lifetime suggest that need to survive only 8 hours of operation prior lifetime and parameters degrading.

Can you upload this photo in better quality?
What is the Preal? As P Re changes and Preal not(exmple 4000s-4500s and 5500s-6000s) than it has to be on different test signals. Was there some more description to this? What test signals are those? Isnt 225W of real power still not much for the speaker. At beginning its voice coil got like 220 deg C. For 225W on worst measured scenario temp was ~170 deg C. Or is 225W B&C recommendation for long lifetime? And whats the enclosure?

A pretty common sense result considering the thermal mass of each I would think. But interesting none the less. There seems to be a lot of discussion currently about voice coil temeprature sensing etc, I should hurry up and build the prototype I have been thinking of for years. Who am I kidding, another 5 years minimum.

It’s not BS. They clearly state the test conditions and that 2400w value is continuous program power. Peak is 4x AES. The issue lies with people not reading up or understanding the test conditions or measuring or designing boxes properly - it’s not just the woodwork, the preset and drive conditions are part of the whole. |

Yes, true - you have to read the small print. Problemn is that a lot of people don´t, then wonder why their speaker blew with 'just' 1k of heavily compressed/clipped waveform.

This post has become refreshing. Notice some Fane 400w 15's in the for sale section, proper loud and lovely with not much input. Maybe sensitivity in drivers will make a come back when they run out of bull?

Quite, I always love the look on peoples faces when I tell them that my mids are only 200w (Studio 12L's), it gets even better when I also tell them that they are set -3db to the rest of the system.

I have a feeling that this thread will be a looong one. Oh, did I interrupt you ? Please proceed with the discussion!

Yes they are exceedingly nice drivers. I'm sure seller will accept offers, if cash collection..

Wait, what? He's got a driver that has reversed its *own* phase after being overheated? How could that possibly work?
