Lookin good bud! I need to get to this stage of my own project to allow enough time for the crossover work. I'm getting more excited every week to hear everyone's designs. I'm especially interested to see how the horn loaded compression drivers do, since I've never messed with them before.
I see you went for the 90 uF polypropylene cap on the mid section, and used a 150 uF NPE cap for the woofer. Any reason you chose NPE for the woofer besides size / price? I'm still trying to learn when to make the trade-off between component cost and project sound. I know there's loads of opinion posts where folks try to compare NPE to poly caps, so I don't intend to interject one of those discussions here... just curious about your design process. Thanks in advance!

Be advised- if it's in the circuit, it's in the signal path. This is AC circuitry, and audiophools don't understand that all parts matter.

110 % correct.

Got the crossovers finalized and tested today, I ended up tweaking the lpad once I had components soldered in place on the board.
I increased R1 to 2 ohms and R3 to 5.6 to get response back to where I wanted it. Basic layout
And loaded up input and output leads
Woofer spade terminals
Mid push terminals
Binding post input leads
Thanks!

Javad, is this how your company builds high performance car parts ? Ben's comments matter because somehow people think that parallel parts in a crossover don't contribute to the sound. Everything in the circuit contributes. Your answer is a little arrogant.craigk

I'd like to politely ask we keep the thread on topic, really not looking to get into a superficial back and forth about semantics, I can safely say I am in agreement with what Ben said and stand behind my clarification.
Thanks,
Javad
