Beston RT002A ribbon tweeter spike at 15k

[awdtalon21]

I am testing out the Beston RT002A ribbon tweeter in my speakers that I have put together. There is about a 4db spike at 15k. Do you think I should try a notch filter here, or could it be caused from the tweeter not being flush mounted yet. It is about a half inch flush from the baffle. This link of someone who has tested the tweeter also shows the spike.

The tweeter crossover is 3.3uf .10mh 10uf. I am kinda concerned of the slope of the tweeter. I wish it more around 24db.

Yes I will flush mount the tweeter but I have a feeling that will not fix anything.

A rise in the UHF (ultra-high-frequency) range makes me suspect the measurement mic.

Is your second attachment only the tweeter output?
Why is it running flat to below 400Hz?

Yes that is tweeter only. I dont understand your question, It should be flat right? It starts to drop off at 30hz.

If only the tweeter is in play, it should roll off somewhere above 1kHz, and be very far down by 400Hz.
I was wondering if you'd left a woofer playing or something.
