Danny, you have mentioned and inferred that ribbon tweeters in an array behave differently than do cone woofers in the sense that the woofer's efficiency will increase the more drivers that are added and the ribbon tweeters don't.
Can you elaborate, or point me to where I can get a better understanding of this phenomenon?
I always thought you get ~3db extra SPL per watt (in their frequency range) for every driver you threw on the fire. Is this different behavior because;
- It is a line array?
- The driver is a planar?
- Of the frequency range?
My curiosity is so that I can better screen drivers without coming to you and saying, "How about this one?" 187 times.
For open baffles, I understand high QTS is good. The fellow that designed the Carver Amazings indicated the ratio between QTS and QMS linearity (whatever that means) is important. I know you say low efficiency is good, but if the old 3db per driver boost rule of thumb works for the woofers and the woofer is 80 db per watt, 16 woofers would make the efficiency 128db per watt, which is unlikely, but would require a very efficient tweeter if they didn't get any boost in multiples.
So as always, I am confused.
