Hi All
First post, so apologies if this is a stupid question.
Here is a tweeter I like the look of but it starts dropping off at 15k: https://www.morelhifi.com/wp-content/uploads/2019/12/ST1048.pdf
At 18k its about 88db which is what I'm aiming for
Is it possible to design a passive high-pass filter that leaves 15k onwards alone and just attenuate everything below 15k? I want to cross it over at 2k.
Cheers 🙂

Use an L pad on the tweeter, and bypass the series resistor with an appropriate value capacitor
(with a resistor in series with the capacitor if needed).
(with a resistor in series with the capacitor if needed).
I believe the term for the circuit described by Rayma is a 'passive low shelf filter'.
It is placed between the crossover components and the tweeter.

Yes, and if the tweeter's top end is too much, add a resistor directly in series with the capacitor.

Amazing, thank you.
Anyone used this tweeter before?
I like the high power handling and the fact you can buy them in matched pairs.
