SLA Pro High pass crossover

I just want to verify that the high pass crossover is the same for the 2, 4, and 6 tweeter options in the SLA Pro. Is that correct? Same circuit for all?

Thank you

Yep....I only see one option in my plans....

Everyone seems to be out of the Dayton 4 ohm resistors. Is a 3.9 or 4.3ohm an option or should I just hunt down a 4ohm resistor?

Within 10% is fine. I would think a 3.9 was better than a 4.3 though, closer anyway.

4.3 is better, as the purpose of that resistor is to set the minimum impedance load the amp can see at very high frequencies, where the capacitive nature of piezos causes their impedance to be very low, approaching a dead short.
