They're in my Tang Band horn, Wolfhorn II.
The knee (low corner, Fc, or what have you) on the TB horn is just below 16Hz, while the SDX horn is at about 16.3Hz. Pretty close. Like I said, each horn is getting 350W. That's all they need to get good and loud in here.
The TB horn integrates rather well with the SDX one. It's more sensitive, so I had to pay attention to calibrating my levels, but other than that I set up my highpass for the SDX design (since those drivers are more sensitive to improper highpass) and let it rip. There's no way any of these drivers will bottom out - I'll run out of amp first.
