Pair Backloaded Horns + Single AMT-1
Parallel FE126 = 3.6Ohm
ESS claims to use a 800hz, 3rd order crossover. Let’s investigate what capcitor and inductors we can actually get, and calculate where the x-over point ends up using parts I can find.
Lets pick out some components….
- L1 = Jantzen .5mH 18AWG $7.98
- L2 = Jantzen 1.1mH 18AWG $11.48
- L3 = Jantzen 0.37mH 18AWG $7.29
- C1 = 40uF 250v $11.98
- C2 = 2x60uF 250V $20.48
- C3 = 75uF 250V $22.98
Let’s proceed to set this up though, let’s model these values in software and see where the x-over point is…
Looks like it hits 806hz at these components, good enough for me.
Update:11-19-19 The Heil has arrived. After some deliberation, constructing a dedicated passive crossover for this setup is inflexible, and given the consideration that I am unlikely to stick with ‘The Horns’ for much longer, I am better served moving to a solution that I can re-use in the next speaker I use. Active digital crossover inbound, and another amplifier.
