Default Measuring tweeter FR without a highpass filter

I want to measure the raw in-box frequency response of my Seas 27TBFC/G and Vifa XG18. I would like to do this using a 170 ms long burst of pink noise at 2.83 volts, with a cutoff frequency of 100hz. The woofer will not be a problem, but I'm not sure about the tweeter. Can the tweeter handle this test without a filter? Should I raise the cut off pink noise frequency to avoid damage?

The only issue I see is room resonances influencing the results.

I will be taking gated measurements, so room reflections will not affect the frequency response. I need 170ms because that is the shortest measurement I can take in Arta. Only the first 6ms will be used.

Yes, provided your conditions there should be no problem.
