This is the schematic from my LRC. Note if you have older 5 ohm neo (that is what you have David) then you do not use 2 ohm 25W resistor in series with neo; schematic shows resistor with 2 ohm resistor.
Brian used a lot of Solen or Axon capacitors. I have no issues with the Dayton Audio 1% Metalized Polyproplene capacitors for larger values say a couple 20uF and then some smaller capacitors (all in parallel) to get your 54.4uF value, the Audyn are nice. Try to get close to shown value since you are not matching another speaker not as critical, but get close.
Custom value of inductors can be ordered from Meniscus Audio. They are reasonably priced and Meniscus throws in a couple pieces of candy (I like their style).
12 or 14 guage hook up wire for woofers, something mil spec stranded 19 strands, silver coated. 14 awg Analysis wire was an upgrade at $2.20/foot. For this application I would just get good Mil wire. Midrange hook-up wire, UL 1213, 18 AWG, 19 Strands, Silver-Coated Copper, TFE, Red (+), Red/Green (-) (or colors of your choosing). Tweeter hook-up wire, UL 1213, 20 AWG, 19 Strands, Silver-Coated Copper, TFE, Green (+), Blue (-) (or colors of your choosing). You can use 18 guage throughout for neo and tweet. eBay has some quality mil wire in short runs say 10 foot for reasonable cost.
Follow the point to point wiring per the schematic, hot glue your large components to cabinet and keep good physical separation of inductors. Double check your work and you are golden. Stuff some fiberglass insulation in cabinet and enjoy.
I replaced a fairly high end center channel with a VMPS LRC in my home theater, really nice upgrade. Goes substantially lower due to cabinet size, but the most substantial upgrade was dialog articulation due to the neo.
