Then look to add the ribbon at least at 5khz and above as that is the lowest freq at which a reasonably priced ribbon can withstand the signal at high levels corresponding to what the T 1D tweeter can do.
In this case, I would go for a 1st order symmetrical XO (passive or active) anywhere in the 5-8 khz range, depending on the power handling of the ribbon you are looking for within that XO range. The other option (what I do right now) is to apply the ribbon for the top half of the top octave without a low pass on the midrange (T 1D tweeter in your case)... That allows more coherence while obtaining the ribbon's fine high frequency extension, and puts down the dreaded "head in a vise" problem of high frequency crossovers. The high pass range in this case would be 12-18 khz, 1st order.
