goto recommends using their tweeter (e.g. SG160), and bringing in @ "5kHz (or more, depending on...)."
thus the lower crossover recommendations for the mid-high driver.

that said, I have listened to SG-370, with the top run wide open, and a ribbon crossed @ 10kHz, 1st order, and heard no signs of distress.
