If anybody would like to build a pair of these speakers, Scott Placke has generously offered to supply all the parts at the OEM price, which is slightly less than $300. You will need to call Scott at PE and tell him you want the RMAF Art Array "kit". There is no "kit", and the Art Arrays have nothing to do with the RMAF, but that's where I see Scott every year, and if you say "Fred's RMAF Art Array Kit" he'll know what you're talking about.
The 33uF electrolytic goes in the woofer zoebel, the 30uF and the 3uF metallized poly caps are paralleled to form the required 33uF in the tweeter circuit. The schematic also calls for a 1.2 ohm series resistor in the tweeter circuit, but I found the tweeter was too bright and substituted a 3 ohm. The 12.5 ohm is used instead of the 15 ohm in Pete's schematic - this value isn't critical. To keep things simple for Scott I request that you order this with no substitutions.
