Serial Crossover Network for VOT 515-8G / 2445J / 2405H

[Dominique]

Hi,
This is my first post on this forum.

I present an experimental crossover to you which gives unexpected results on my system : All the loudspeakers seem to be only one!

Fc : 640 Hz, 7 300 Hz
Did somebody already test it? What do you think about it?

I re-draw your schematic in my circuit simulation. Please take a look if there is any error from your circuit.

Hi CauYem,
Please consider that :
- All connecting points (inputs and loudspeakers) are "+" and "-" but not "input" and "ground".
- All the loudspeakers are actualy series connected.
- As you know, "JBL 2445J" is 16 Ohm and "JBL 2445H" is 8 Ohm.

You'd better to re-draw my schematic in your simulation tool.


On the trace below, the yellow (not easy to see at 1.0V) is the sum (green+red+blue)
