I'm sure SH, for one, will have an answer for this.
Is there a method for a guy with normal audio components to produce a 1 watt signal so I can duplicate the industries standard method of measuring speaker efficiency.
Contacting the manufacturer is not an option, as I made em myself and I don't know!!
UNLESS: I do know the published sensitivity of each driver in the speaker, so would the result be an average of all the drivers?
Which brings up another question.
At what frequency does a manufacturer measure the sensitivity? If he measures at 40hz with a 10" driver in a 3-way, and that drivers sensitivity is 90Db, he will get a different result than measuring at 10Khz if the tweeters sensitivity is 93Db.
That said, he must be averaging right ? or does the passive crossover mess with this?
