I am building the NX Center crossover in the same way I built my Otica crossovers. I am using plexiglass as the base for mounting all the components. Drilling holes and running all the wiring shrink wrapped in black, over a black base. This way, you wont see the “mess” underneath. Looks very clean. I use 3M hemispherical rubber standoffs. Then on the black base use plastic chromed feet so there is no metal messing with the inductors. Looks metal, all plastic.
Initially I planned to use the supplied sonicaps and GR wire wound resistors with a foil inductor upgrade on the mid. I received all the parts and just couldnt help myself but to order “upgrades” for everything. The only thing I didnt customize was the large inductor for the lower woofers. A copper foil of that value would be the size of a basketball and cost a fortune. I looked into into it. Not worth it.
For the rest I had planned to use all hard to find miflex copper foil caps (miflex out of business) until I saw some of the values could not be sourced. I settled on mostly a complete Vcap ODAM nest of caps utilizing Deulund silver copper CAST hybrid bypass on the tweeter and miflex coppers on the mids. I used miflex coppers on the other smaller value caps as well. For the resistors I like the Path Audio resistors. I know Danny doesn't like them because they have metal ends. My personal choice only on those. I upgraded all the inductors to copper foil except the big woofer coil.
The major point of back and forth was using the provided tube connectors. I elected to go with pure copper binding posts. I know, I know, the higher mass copper might lose performance. I just like the flexibility and look and ease of installation that a solid copper post provides. My really nice, already ran through the wall, speaker cable utilizes bananas and this is just a simpler solution for me.
