I am looking to upgrade the x-overs on my 2.3tl's and was going to use all Dayton Metallized 1% Polypropylene. In some cases I will have to use two and piggyback to get exact values as can be seen in the pics. I am either going to use Dayton 20 ohm 10 watt non inductive resistors or Mills 20 ohm 12 watt non inductive resistor in place of the stock 22.5 ohm, I will use the Mills if it will make a big difference. I understand that you don't need the 750pF piggybacking the caps like on stock when you use good caps like these if thats correct? I put a picture of the unaltered and my proposed altered pic. Any thoughts advice would be appreciated.
