Default Want to build a TH, don't know what to do next.

I got a pair of old pioneer 3-way 8 inch (20cm) speakers, want to try to make TH with one of them measured t/s parameters are:
Thiele-Small parameters:

Fs = 60.32 Hz
Re = 3.80 ohms[dc]
Le = 1110.11 uH
L2 = 15544.16 uH
R2 = 15.30 ohms
Qt = 0.19
Qes = 0.20
Qms = 5.72
Mms = 31.15 grams
Rms = 2.062644 kg/s
Cms = 0.000224 m/N
Vas = 30.98 liters
Sd= 314.16 cm^2
Bl = 15.094156 Tm
ETA = 3.32 %
Lp(2.83V/1m) = 100.55 dB

Added Mass Method:
Added mass = 9.80 grams
Diameter= 20.00 cm
I have entered parameters in hornresp, set Vrc, Lrc, Vtc, Atc to 0 and in tools>driver arrangement set it to TH. Can someone tell me, step by step, what should I be doing next?
