Yes, it is possible. I suggest having a look at the datasheet for the chip that's in your amp, or the sheet for the amp itself, to see what sort of filter you've got. Once you've got the filter type and component values, the calculations themselves aren't too hard.
I am yoursing a T-amp now. but i am making amp 9 from 41hz. What values do i need, the impedans of the speakers is 3 ohm.

The rising top end may be due to an inductive impedance component of the ribbons interacting with the output filter of the amplifier. Try to flatten it with a RC series network at the output of the class D amplifier, with R in the range of 3 ohms and C in the range of 5uF. Most class-D designs expect a purely resistive load in the upper two octaves.
maybe your right Eva. this is the impedans of the ribbon.
