1.5 to 2.5 db over at 10KHz will get you in the ball park.

Instead of speculating, here's the info:

According to the bias recommendations published by BASF, the bias for a JH-110 at 30 ips using 911 is 1.5 dB overbias @ 10K. If you wish to set it up for 15ips, bias it at 3.0db over.

hope this helps,
