There are Two new drivers by Audio Nirvana available.
there's a new 8" AlNiCo full ranger, and a 15"!
While I wouldn't call the 15 a Full range driver, the specs state an Fs of 27Hz topping at 14K, with a Qts of .48 there's several things that come to mind where this might be fun, though the cone mass seems a little high... the possibility for dynamics with this kind of driver...... Crossed to your favorite tweeter at 10K....
Just an FYI. Since I'm currently economically disadvantaged, I'll just have to dream a while.
