OK Mike answered your questions..Pretty much what i was going to say..But i personally like to keep the values closer together.. When working with 2 similar size caps it is easier to work with than one big one and one tiny one.. A 1uF cap is quite small..Also looks a lot better I think.No sonic difference that i can tell however.The L-pads are those big round things on the back of the black aluminum plate...

These are the L-pads I use https://www.madisoundspeakerstore.co...w-8-ohm-l-pad/.
