Well I think I'm getting somewhere with this crossover design stuff. I started with X-over Pro and moved on up to LspCAD to simulate the crossover. Below is the schematic and response:
I started with a 2nd order APC design and customized it somewhat to get a steeper slope on the low-pass section of the bandpass network. I put Zobels on everything and L-pads on the tweeter and woofers, as you can see in the image.
A note about the tweeter output though...I'm not planning to use the RS28A in my final design. I plan to use the Vifa XT25 instead, which will eliminate the big dip in response above 10K.
One question I still have has to do with the component values for the Zobel filters. X-over Pro says one thing, but if I calculate them manually I get very different values. I'm not sure who to believe. What I have here in the schematic is the manually calculated values.
Does anyone see anything wrong with it?
Feel free to comment about it...
